Left 4 Dead includes achievements for Steamworks and Xbox LIVE. There are 73 achievements in all for the PC version of Left 4 Dead, but only 65 for the Xbox 360 version; the Outbreak achievement is not in the Xbox 360 version of the game and Survival Pack on Xbox 360 adds no new achievement due to technically being only a patch, not a DLC. There are currently 70 achievements for the PC version of Left 4 Dead 2 (one of which can no longer be earned) and 65 achievements for the Xbox 360 version.

  • Survival Pack adds 7 new achievements to Left 4 Dead for the PC version only.
  • Crash Course adds 10 new achievements to Left 4 Dead.
  • The Passing adds 10 new achievements to Left 4 Dead 2.
  • The Sacrifice adds 5 new achievements to both Left 4 Dead and Left 4 Dead 2, and for the Xbox 360 and PC as well as Mac.
  • The Cold Stream update currently adds 2 new achievements to Left 4 Dead 2 called Stream Crosser and Connecting Fight, although the latter achievement is actually keyed to the conversion of the Dead Air campaign in Left 4 Dead 2. As a reward for 60,000 players earning the Connecting Fight achievement, Valve released the beta version of the Blood Harvest campaign for Left 4 Dead 2.
  • A special holiday-themed achievement, called Valve Gift Grab 2011 - L4D2, was added to the PC version of Left 4 Dead 2 for a limited time in late December 2011.
  • The achievement Good Guy Nick tells you to survive a campaign with free weekend players

Note: Since the Crash Course update, achievements cannot be earned with cheats turned on (sv_cheats = 1). However, one way is to play on Versus mode with everyone helping each other to get achievements.

Left 4 Dead Edit

Campaign Edit

L4d no mercy MERCY KILLER (15G)
Survive the No Mercy campaign.
  • This can be acquired by surviving the campaign on any difficulty.
  • "Mercy killing" is another term for euthanasia.



L4d achievement survive garage CRASH-PROOF (15G)
Survive the Crash Course Campaign.
  • This can be acquired by completing the campaign on any difficulty.
  • Crash-Proof is a play on the term "bulletproof."



L4d death toll TOLL COLLECTOR (15G)
Survive the Death Toll Campaign.
  • This can be acquired by completing the campaign on any difficulty.
  • A toll collector is someone who collects a toll that must be paid for using a bridge, ferry, or other tolled transportation.
  • This is also a reference to Charon, who collected a toll from those trying to cross the river Styx in the underworld.
  • It may also be a reference to the bell that tolls in the Church level.



L4d dead air DEAD BARON (15G)
Survive the Dead Air campaign.
  • This can be acquired by completing the campaign on any difficulty.
  • This achievement's name is a parody of the Red Baron.



L4d blood harvest GRIM REAPER (15G)
Survive the Blood Harvest campaign.
  • This can be acquired by completing the campaign on any difficulty.
  • The Grim Reaper is the mythological physical embodiment of death, who is often portrayed with a scythe (a traditional farming tool).


SurvivorEdit

L4d drag and drop DRAG AND DROP (20G)
Rescue a Survivor from a Smoker's tongue before they take damage.
  • This requires you to shoot a Smoker who has grabbed a player. It takes until the Smoker drags the character directly to the Smoker before the Smoker can deal damage.
  • Just as the Survivor is grabbed by Smoker quickly melee the Survivor or shoot the Smoker
  • Smokers inflict dragging damage in Versus mode, it is easier to achieve this in the other modes.
  • The achievement title is a reference to a term used in computing that is the action of selecting a virtual object by "grabbing" it and moving it to a different location or onto another virtual object.



L4d brain salad BRAIN SALAD (15G)
Make 100 headshot kills.
  • Aim high when firing into Infected crowds with a shotgun, pick off Infected from a distance if they haven't noticed you yet, and remember that crouching improves accuracy with most guns. Even if you're not trying to get this achievement, you'll probably get it after a while of playing the game normally.
  • A successful headshot with any weapon will kill a Common Infected on any difficulty, so feel free to use Pistols.
  • This is easiest to achieve during The Town. Simply use the Hunting Rifle and pick off wandering infected from atop the roof. If you go back into the building, chances are, a few will respawn (or hidden ones will show themselves). Since you're almost literally inside the saferoom, you have unlimited ammo. Just be aware, doing this for too long will provoke a Horde attack.
  • The achievement title may be reference to Emerson, Lake & Palmer's 4th studio album Brain Salad Surgery which is considered a "masterpiece" by their fans.



L4d tongue twister TONGUE TWISTER (20G)
Kill a Smoker who has grabbed you with his tongue.
  • You MUST shoot the Smoker as soon as it grabs you. You have roughly a second to kill the Smoker.
  • If the Smoker grabs you by its tongue, quickly turn and shoot him. Assault Rifle or Hunting Rifle is preferred due to their long range. If you wait long enough you will be constricted and won't be able to kill him.
  • Use of the 180 flip could help one to quickly face the smoker constricting them from behind.
  • A tongue-twister is a phrase that is difficult to say.



L4d pyrotechnician PYROTECHNICIAN (20G)
Blow up 20 Infected in a single explosion.
  • Throw a pipe bomb when you see a large horde approaching, such as a panic event. Also throw a Pipe bomb if you enter a large area filled with idle Infected.
  • You can fulfill this achievement either by throwing a pipe bomb or by blowing up explosives. This achievement should be attempted in finales or Crescendo Event, as at those times there are a lot of Infected in large groups. A perfect instance to do this is the start of Dead Air where there is a Pipe bomb on the table. All you need to do is pick it up and throw it over the wall at the Infected without opening the door.
  • A pyrotechnician is someone who specializes in the handling of explosives, usually for entertainment purposes.
  • It is possible to get this Achievement by blowing up a Propane Tank . It is easier done by shooting a gas can that will blow up the Propane Tank because it is difficult to spot during a Horde. This can be easily achieved in The Lighthouse on the Street that leads to the Gate.



L4d blind luck BLIND LUCK (20G)
You or another Survivor take no damage after being vomited on by a Boomer.
  • While you or another Survivor is covered in bile, throw a Pipe bomb to lure away most of the Infected. This should leave you with a good chance of receiving no damage.
  • Try to be vomited in a room with a single entry. That way you and your teammates can cover the entrance easier. The preferred weapons are the Auto Shotgun and the Assault Rifle. Try not to hit your teammates during the attack. You can also try throwing a Pipe bomb. Note that the time you count as being "vomited on" is sightly longer than the time your screen is covered in bile, so the safest option is to wait until you get the achievement notification.
  • If only one or two people have been slimed, they should move to the back of the room/closet. The horde will only attack them, and being at the back will give the team more time to thin the Infected numbers. Aside from that, employ standard turtling tactics (Survivors in the front crouch, shoot, and melee, and Survivors in the back fire over them). If you're slimed and don't know what you're aiming at, melee spam.
  • Blind luck is a term for a favorable outcome when the affected party had little opportunity to affect the outcome. Here, blind refers to the Survivors' visions being blurred by the vomit.



L4d my bodyguard MY BODYGUARD (15G)
Protect any Survivor from an attacking Infected 50 times.
  • Whenever you shoot an Infected attacking another person, a message will pop up saying you just protected that person. You must do this 50 times. This is gained by using melee or shooting to get Hunters and Smokers off Survivors, or shooting a Common Infected that is attacking an unaware Survivor in the back.
  • Watch your teammates' backs excessively when a horde is attacking. You can get this achievement just by playing long enough.
  • You can still protect your teammates while incapacitated. Simply fire your Pistol(s) from the ground.
  • Protecting a Survivor from a Special Infected while incapacitated will also earn you the achievement 'Ground Cover' in the process.
  • The achievement title is likely a reference to the 1980 film of the same name.



L4d tankbusters TANKBUSTERS (20G)
Kill a Tank without it dealing any damage to a Survivor.
  • ALWAYS keep your distance from the Tank. As long as your health is high enough, you can easily outrun him, but don't let him get too close.
  • Set the Tank on fire at your own peril. Fire will kill him within 30 seconds, but it will also make him MUCH faster (outside of versus).
  • When running backwards and firing at the Tank, make sure you know where you're going. If you get stuck on the scenery and it's coming after you, you're probably screwed.
  • If the Tank is about to throw rubble in your direction, take cover unless you're sure you can pull off the zigzag method (i.e. running in one direction, then the opposite direction right after he throws the concrete). You can destroy thrown rubble by shooting it, but this is also unreliable without practice.
  • Best done in a campaign on easy with human players (AI's make no effort to avoid the Tank's thrown rocks.) When a Tank attacks, run away from it while focusing all fire on it. Tanks on easy will die in a matter of moments from concentrated gunfire.
  • Your health needs to be 40% or above to outrun the Tank. Try to be in an open space when faced with a Tank. If the Tank charges at you, run backwards as fast as you can but don't get separated from your teammates. If the Tank picks up some rubble, change your position. Try to engage the Tank with medium to long range weapon such as assault rifles. Nothing drops a Tank faster than Auto Shotguns at shorter ranges, but only use one if you're a competent backpedaler. Getting stuck on scenery or a wall while the Tank is coming for you means screwing up the achievement for everyone.
  • The achievement title may be a reference to the movie Ghostbusters.
  • This achievement is ludicrously easy on easy difficulty, where the Tank can be killed with only a focus fire from 3-4 Submachine Gun magazines.
  • "Tankbuster" is military slang for an anti-tank weapon.



L4d no smoking section NO SMOKING SECTION (15G)
Kill 10 Smokers as they are pulling helpless Survivors.
  • You must shoot a Smoker to the death while it is actually dragging the Survivor, and before the Survivor is dragged into an obstacle or the Smoker itself.
  • "No Smoking Section" refers to an area in a public location, such as a restaurant, where smoking tobacco is not permitted.



L4d hero closet HERO CLOSET (10G)
Rescue a Survivor trapped in a closet.
  • This is an easy achievement to get. Once a Survivor dies, they will respawn in a closet. This happens after 1 minute, and after the rest of the Survivors move a certain distance from the dead body. Once the Survivor respawns, they will call out. They will have an orange outline while in a closet. Once found, open the closet to save them. This doesn't work if your teammate does it; you have to be the one to open the door.



L4d hunter punter HUNTER PUNTER (10G)
Shove a Hunter off of a pinned and helpless Survivor.
  • You must free a pinned Survivor by using melee to hit the Hunter off him or her. You don't need to kill the Hunter, just melee him away.



L4d 101 cremations 101 CREMATIONS (20G)
Set 101 Infected on fire.
  • Using molotovs or gas cans is the only way to gain this achievement. You must light 101 Infected on fire. Throw a Molotov in the path of a charging Horde to light them all on fire.
  • To set Infected on fire, you must throw a Molotov cocktail at them or light a gas can when they are near it. A gas can is recommended because of its large area of effect and longer burn. During a Panic Event, Crescendo Event, or a finale, throw the Molotov where the Infected are coming from, or in a central area, and you should get this achievement. Note that this is a cumulative achievement, which means that every time you burn an Infected, it adds up. You don't need to burn all 101 at once.
  • It is recommended to do this on Dead Air, in the first chapter. At the beginning there is always a big crowd behind the door and there are always four pipe bombs and four Molotov. First throw a Molotov in the greenhouse, then a pipe bomb in the flame. All Infected will run into the flames and that will count for the achievement.
  • This achievement's name is a parody of 101 Dalmatians.



L4d towering inferno TOWERING INFERNO (10G)
Light a Tank on fire with a molotov
  • During most finales you will fight a Tank. Simply set it alight by either throwing a Molotov in its path, or shooting a gas can near it. This is easier to do in campaign; A.I. Tanks will do nothing to avoid a Molotov fire and will gladly charge right through it.
  • In the starting safe room of the No Mercy finale, there will be a Molotov. At least one Tank will spawn during a finale, although there are usually two. Simply throw the Molotov when the Tank is in a good position and the achievement will be earned. Try to throw a Molotov at him when he's climbing up something or throwing concrete.
  • The Towering Inferno is a movie about a skyscraper being set on fire.



L4d achievement tank explosion stun TANK STUMBLE (20G)
Stun a Tank with an explosion in the Crash Course campaign.
  • Pipe Bombs or a Propane tank will cause a Tank to stumble around, and doing so will unlock the achievement.
  • This achievement reuses the image from the Ground Cover achievement.
  • Shooting a Boomer next to a Tank will also stumble it but it is unknown if this counts toward the achievement.



L4d witch hunter WITCH HUNTER (20G)
Kill a Witch without any Survivor taking damage from her.
  • If you get the Cr0wnd achievement, then you will also get this achievement. Focus on that achievement if you want both.
  • Startle a Witch from a distance and have everyone focus fire on her. If you do, she will likely die before reaching you.
  • Real life witch-hunters are still active to this day in some countries, but they peaked in activity between 1480 to 1700.



L4d ground cover GROUND COVER (30G)
Save another Survivor from a Special Infected while on the ground.
  • While on the ground, you must kill a Hunter or Smoker who has pinned someone, or kill a Special Infected who is in close enough proximity to another Survivor to count as protecting them. It is possible, though unlikely, to get this achievement by scoring the killing shot on a Tank.
  • Usually after being incapacitated, another Survivor will attempt to lift you back to your feet. It is very common that, while the Survivor is pulling you up, he or she may be pounced by a Hunter or pulled by a Smoker. As soon as you see this happen, begin blasting the Hunter or Smoker with your Pistol. The Special Infected will go down faster than you think, and the achievement will be yours. The reason this is not too easily earned is due to a small luck factor that affects it. This is because the chances of another Survivor being pounced or dragged is quite slim if you are in a group of good players. It happens often in Versus, since the Infected will focus on your teammate while he's helping you.
  • Another way to get this achievement is to throw a Molotov at your feet a few seconds before a Hunter pounces you. (Make sure it's actually targeting you and not another Survivor, or you'll just waste health.) The fire damage coupled with the Hunter mauling you should be enough to incapacitate you, and as long as no other Survivors interfere, the flames should kill the Hunter before you're killed, ironically giving you the achievement for saving yourself.



L4d spinal tap SPINAL TAP (10G)
Kill an Infected with a single blow from behind.
  • When things are quiet, simply approach an Infected that has not yet noticed you and melee it in the back.
  • It is easier to attain this achievement in buildings and rooms where the Infected have a tendency to face the wall, leaving their backs open to an easy melee attack and subsequent kill.
  • An easy way to get this is to start on the Tunnel and head into the offices next to the saferoom. 2 or 3 Infected are almost always facing the wall in these rooms.
  • If a Survivor has been swarmed by a horde, run up to the swarm and melee the Infected in the back.
  • A spinal tap is a real life medical procedure to collect cerebrospinal fluids, which can aid in various diagnoses.
  • Spinal Tap is also a fictional band, subject of the 1984 mockumentary This Is Spinal Tap.
  • It is also the name of one of the Medic's taunts in Team Fortress 2.



L4d dead stop DEAD STOP (10G)
Punch a Hunter as he is pouncing.
  • You must melee a Hunter as he is flying through the air.
  • Getting this achievement is a combination of luck and timing. Hit melee the instant before a pouncing Hunter reaches you.
  • It is possible, yet very hard and very lucky, to get this achievement while blinded by Boomer bile.



L4d burn the witch BURN THE WITCH (10G)
Light a Witch with a molotov.
  • Note that setting a Witch on fire will make her come after you, even if you didn't startle her. Normally, Witches leave after killing whoever startled them, but setting them on fire after they've killed their victim will send them into another frenzy. Therefore, attempt this achievement with care.
  • Simply throw a Molotov at a Witch as she is on the ground. Be ready, however, as she will still attack you while on fire.
  • She is more difficult to trick when on fire, so avoiding her is far more difficult.
  • She will, however, move slower when on fire, allowing you to run away without her catching up.
  • A burning Witch will only last for 15 seconds before dying.
  • Note: This can also be achieved by lighting a Witch on fire with a gas can.
  • This achievement is a reference to the Salem witch trials and witch-hunting in general.
  • The achievement title may be a reference to the film Monty Python and the Holy Grail in which is a scene where a group of villagers attempt to execute a woman for being a witch, despite the fact that the crowd has dressed her up and is falsely accusing her. The throng are introduced in the scene shouting "Burn the witch!"
  • The achievement title may also reference a 2006 single of the same name by the band Queens of the Stone Age.
  • This achievement shares it's name with an achievement in the Xbox 360 game, Banjo-Kazooie: Nuts 'n' Bolts where the player must fire a laser at the main antagonist of the game, who is a witch.



L4d noone left behind NO-ONE LEFT BEHIND (20G)
Beat a campaign with all 4 Survivors.
  • This can be acquired on any campaign on any difficulty. During the finale, all four Survivors must get into the rescue vehicle.
  • This achievement may be a reference to the movie Blackhawk Down.
  • Due to the nature of its finale, this achievement cannot be earned on The Sacrifice.
  • Possibly a reference to No Child Left Behind.



L4d achievement win versus garage SMASH HIT (25G)
Win a Versus campaign of Crash Course.
  • This is unlocked by simply winning any round of a Versus campaign in Crash Course.
  • This achievement is broken or glitched on the Xbox 360 and will only unlock if playing a versus game on a local server (see Crash Course notes section for information on forcing a versus game into a local server).



L4d jump shot JUMP SHOT (20G)
Headshot a Hunter while he's leaping.
  • Grab an Assault Rifle or Auto Shotgun, crouch down and fire full auto at the Hunter as it jumps toward you.
  • A jump shot is a basketball move, where you shoot the ball after you jump into the air. Here it's a play on that term: They jump, you shoot.
  • This achievement re-uses the picture on Dead Stop.
  • It's possible to earn this achievement without killing the Hunter as you only have to headshot it, not kill it.



L4d clean kill CLEAN KILL (10G)
Shove a Boomer and then kill him without him splashing on anyone.
  • This will usually require an open space. Melee the Boomer, retreat while he's stunned and shoot him. Note that meleeing the same Boomer too many times will make it explode all over you.
  • A clean kill is a term used by hunters and shooters to refer to a kill that was done with one hit and resulted in little blood being spilled.
  • It seems difficult to get this achievement in Campaign mode. Playing in Single Player grants this achievement easily.



L4d achievement repower generator QUICK POWER (25G)
Restart the generator within 30 seconds of it shutting off in the Crash Course campaign.
  • This is acquired in the Crash Course Campaign, when the generator shuts off. Turning it on within 30 seconds will unlock this achievement.



L4d dead giveaway DEAD GIVEAWAY (10G)
Heal a fellow Survivor when your own health is below 10.
  • This can be frustrating to get in Single Player, as usually if your health falls below half, a Survivor Bot will heal you.
  • If you play with the Survivor Bots and you don't want them to heal you, select your first aid kit in your inventory. Having pill health and no permanent health will also count.



L4d helping hand HELPING HAND (20G)
Revive 50 incapacitated Survivors.
  • You only have to help Survivors onto their feet 50 times. You do NOT have to heal them.
  • Helping up Survivors incapacitated due to friendly fire still counts towards this achievement, even if your friendly fire caused them to be incapacitated. This can be easily abused to gain the achievement in single player mode.



L4d back 2 help BACK 2 HELP (20G)
Leave a safe room to save an incapacitated teammate and bring them back safely.
  • Can be done on any difficulty except easy by downing a team mate while in the safe room, then helping them up as they are incapacitated outside of the room. (Note: This seems to have changed. Your ally must be downed by an Infected for this achievement to count).
  • Also note that the achievement does not pop until the rescued survivor enters the safe room.



L4d pharm assist PHARM-ASSIST (20G)
Give pain pills to 10 Survivors.
  • Simply give your Pain pills to 10 Survivors. They must use the pills for it to count toward the achievement.



L4d field medic FIELD MEDIC (20G)
Heal 25 Survivors with a first aid kit.
  • Self-explanatory. You can easily get this achievement in single player by starting a game, doing friendly fire damage to a teammate, and healing them.
  • If you really want to cheat, play through the first level of a campaign on Easy, take as little damage as possible, and make it to the saferoom. Ideally, your whole team will have first-aid kits. Now, switch the difficulty to normal or higher, shoot your teammates, and heal them with the full stock of first-aid kits. After that, restart the level, rinse, repeat.



L4d cr0wned CR0WND (30G)
Kill a Witch with a single headshot.
  • Cr0wn simply means to kill a Witch without startling her. Because of this you can get cr0wned using the hunting rifle, contrary to popular belief. A shot to the head using the hunting rifle causes her to stumble, but she won't be startled until the stumble wears off. This gives you roughly 3 or 4 seconds to run over to her and melee her while shooting her. She will not be startled during all of this if you don't give her the chance to and you can get the achievement. See also: Modern Way To Kill Witch 2009
  • Sneak up right behind a Witch. She will not attack right away and slowly get up. Aim the shotgun right at her head. When she stands up and is about to be startled, shoot her right in the head. You will have some time to aim before she becomes startled, but don't take too long.
  • Don't go for this achievement if you are actually trying to beat the campaign. Play on single-player for the exclusive reason of earning this achievement. That way, you won't have to worry about screwing up.
  • With some luck, the Witch may spawn within sight and range of a mounted gun. With a little more luck, you can Cr0wn her by firing upon her with that mounted gun.
  • This achievement's name is a pun, but the basis of the pun is disputed. Some feel it is a combination of "crone" and "0wnd", other say it is a "1337" form of crowned.
  • An easy way to get this achievement, is to turn off your flashlight, sneak up behind the Witch and aim to the back of her head. As she is getting up (after looking up at you) shoot her in the back of the head, when she takes her eyes off of you, and turns back around, before she gets up.
  • Crouching can also improve accuracy, if using a shotgun. Try to follow her head as she starts to stand up, or aim for her chin. If you're not very good or are inexperienced at cr0wning, shoot more than once, just to make sure.



L4d zombie genocidest ZOMBIE GENOCIDEST (20G)
Kill 53,595 Infected.
  • Play the game for a long enough time and you'll eventually get this one.
  • A quicker way to do this Achievement is to play through a finale as normal and then when the rescue vehicle arrives stay and hold out until you die while killing as many Infected as you can. It's best doing it in a glitches spot where the Infected cannot get you such as the "Jesus room," which is still unpatched on the 360 version.
  • This is a reference to the game Dead Rising, in which if you kill 53,594 zombies, it grants the "Zombie Genocider" achievement; Frank West, the player, has killed, down to a man, the entire population of Willamette. In order to outdo Dead Rising, Valve included this achievement and added one more to the kill count. "Genocidest" functions as a play on words: going from the comparative suffix "er" (of Genocider) to the superlative suffix "est" emphasizes Valve's one-upmanship.
  • This number is referenced in a set of safe house graffiti in the No Mercy campaign, with different inscriptions claiming 40, 50, 120 and finally "53,595!!!" zombie kills. This one in particular is underscored by the declaration: "LIES!!!"
  • Any kills done in split screen by a guest also adds to your kill count.
  • This achievement was later referenced by the game Prototype, which requires the player to kill 53,596 Infected in order to obtain the "Trail of Corpses" achievement.
  • In the Crash Course DLC, the achievement, 'The Littlest Genocide' also references this achievement, but with only 1/10 of the zombies required.
  • The easiest way to get this, is by going to The Terminal in the Dead Air campaign on expert, opening the door, and walking out, then back in to wait for the hordes that spawn after a bit.



L4d man vs tank MAN VS TANK (30G)
Single-handedly kill a Tank.
  • Best done on easy single-player. Listen for the sounds of a Tank growling before the he actually attacks. Turn on your subtitles to help. When you hear the Tank, change the difficulty to expert and kill your AI companions to prevent interference. Change the difficulty back to easy and take on the Tank. With a Tier 2 weapon, a Survivor on his own won't have too much trouble taking the Tank down.
  • Set him on fire, don't let anyone shoot him, and just run away until he burns.
  • This achievement is a reference to the Unknown Rebel. It may also be a reference to the TV show Man vs. Wild.
  • During the finale of The Sacrifice, the player sacrificing themselves may get this achievement. It is unknown whether it is a glitch or if intended by Valve, seeing as Bill took on three Tanks shortly before his death in The Sacrifice comic.
  • Despite the name of the achievement, it is possible to get it while playing as Zoey, who is not a man.



L4d achievement 5359 infected garage THE LITTLEST GENOCIDE (25G)
Kill 5,359 Infected in the Crash Course campaign.
  • This is unlocked by killing 5,359 Infected within the two maps of the Crash Course campaign.
  • This is an obvious reference to the Zombie Genocidest achievement.
  • This achievement requires only 1/10 of the zombies required in the Zombie Genocidest, but it has a larger reward.



L4d untouchables UNTOUCHABLES (30G)
No Survivors take damage after contacting the rescue vehicle.
  • There are map-specific glitches which can help with this achievement. See the finale pages to get more tactics.
  • A good way to get this achievement on the Xbox 360 is to go to the finale on the Dead Air campaign and stand in the back of the map on the left corner. The bots should take care of all Infected, leaving the human player(s) completely safe. This doesn't work on the PC version.
  • The achievement takes into account only your telemetry. Therefore if you join a nearly-finished game where the Survivors only need to get in the escape vehicle and no one takes damage you will still get the achievement. Furthermore, the game doesn't track your stats, including damage, when you're idle; as soon as the finale starts, hit Esc and select Take a Break. Now wait until the finale is over and almost everyone are in/next to the escape vehicle, then re-enter the game.
  • If a Survivor takes pain pills, the temporary health reduction will count as damage and prevent the achievement from being earned.



L4d red mist RED MIST (20G)
Kill 1000 Infected with a mounted machine gun.
  • In finales & Crescendo Event, there is usually a mounted Minigun. Use it as frequently as possible.
  • There are miniguns at each finale except for Blood Harvest, along with certain crescendo events. These are the first crescendo event in No Mercy, and the third crescendo event in Death Toll. Use these miniguns enough and you will gain this achievement. A somewhat useful trick is to throw a pipe bomb in front of the line of sight of the minigun and kill the infected that gather.
  • "Red mist" a term for a cloud of blood.


Full Campaign AchievementsEdit

L4d stomach upset STOMACH UPSET (20G)
All Survivors complete a campaign without being vomited on.
  • This is a combination of luck and skill.
  • Always hit nothing but melee if you hear a Boomer. All it takes is one trigger-happy Survivor to ruin it for everyone.
  • The name of this achievement is a play on the term "upset stomach", a term often used to describe nausea, which is a common cause of vomiting.
  • It is highly likely that restarting a campaign in-game instead of the lobby will count as one large campaign, frustratingly nullifying the achievement.



L4d saftey first SAFETY FIRST (30G)
Play an entire campaign with no Survivors taking friendly fire damage.
  • Although friendly fire does not cause damage on easy, it still registers as friendly fire and the achievement will not be unlocked.
  • When a Survivor is surrounded, allow him to help himself, or use melees to assist him.
  • This can be easily done on a campaign where the other three players are bots, because they won't cause friendly-fire damage from firearms. However a bot can cause friendly fire damage if one accidentally sets off a gas can or propane tank next to the player. So just as long as you avoid hitting the bots, and stand clear of explosive items, you'll get the achievement.
  • This can also be done by 4 players meleeing through the entire campaign, although it is impossible to deal with the Tank head-on in this way.
  • An alternative way is to play through a Single Player campaign in Easy, then melee through the entire campaign.
  • The image of the achievement might be a hint to use the Hunting Rifle as it is more precise than the other full auto weapons and has less chance of hitting another Survivor.
  • While it is very rare, bots do have the ability to have a stray bullet hit a gas can or propane tank and the explosion will hurt you and count as friendly fire. Destroy the items preemptively or move them so the bots can't shoot it by mistake.



L4d do not disturb DO NOT DISTURB (20G)
Sneak past all Witches in a campaign without disturbing one.
  • This only requires you to get through ONE campaign without startling a Witch. Simply listen for the signs on a Witch. Cr0wning her will not count as startling her. Only when it says "x has startled the Witch" will it count against the achievement. If she is directly in your way, have one-two people run by her at a time.
  • Play on Easy. There will be some instances where a Witch is literally sitting IN a doorway you must pass through, and cr0wning will be necessary. Cr0wning is obviously easiest to do on easy.



L4d zombicidal maniac ZOMBICIDAL MANIAC (30G)
Survive any campaign on Expert.
  • "Simply" survive one campaign on expert to get these achievements.
  • Only the Survivors who make it to the rescue vehicle will get this achievement.



L4d stand tall STAND TALL (20G)
Survive a campaign without being incapacitated.
  • This can be done on any difficulty, so play on Easy if you're specifically going for this one. It's very doable in single player, but having a good human-controlled team practically makes this achievement guaranteed.
  • Avoid attacking Witches, as they can cause instant incapacitation and will ruin your chances of getting this achievement.
  • Heal when you fall below 60 health just in case things take a turn for the worse. More health is better then low health and being caught.



L4d what are you trying to prove WHAT ARE YOU TRYING TO PROVE? (35G)
Survive all campaigns on Expert.
  • "Simply" complete all the campaigns on expert to get this achievement.
  • A 'cheat' for this is to play campaign online with more than 2 Players at least and then do Chapters 1-4 on a campaign on Easy; then when you're at the finale, don't open the saferoom door and vote to return to lobby and change the chapter of the campaign you were doing to the Finale and the difficulty to Expert and then you only need to finish the finale on expert and not the whole Campaign.
  • This may also be an easter egg to Valve's popular game, Half-Life 2, where the antagonist Wallace Breen asks the silent protagonist Gordon Freeman, "What are you trying to prove?", since the player must go through many hardships to survive.



L4d unbreakable UNBREAKABLE (30G)
Finish a campaign without being healed by a first aid kit.
  • Being healed by another Survivor counts as being healed.
  • Note that you CAN consume pain pills.
  • If you attempt this with AI players who then try to heal you, in order to cancel this, select a First aid kit you have in your inventory, otherwise there is no way to stop the AI from healing you. However, you will have to constantly stop and do this, every few moments. It is generally a much better idea to do the achievement with human players and on lower difficulties.
  • If you are playing an online campaign, going idle before the heal process completes will allow you to be healed, but won't count against the achievement. This way, you can be healed and still get Unbreakable.
  • If you have low health and you are near the end of the level you can have a human partner kill you so you come back with 50 health (if you die in a safehouse all your supplies will carry over to the next level as long as they are IN the safehouse).
  • If you are at the finale and are incapped, as long as you don't die before everyone else reaches the Rescue vehicle, the achievement is still unlocked.
  • The achievement's name may be a reference to the film Unbreakable staring Bruce Willis playing the role of a man who never requires medical treatment due to self-healing powers.



L4d nothing special NOTHING SPECIAL (30G)
Survive a campaign with no Survivors taking damage from Special Infected.
  • Special Infected are usually very tenacious, so use your weapons with equal tenacity.
  • It is possible to do this on Versus Mode, just gather up a group of friends and when playing as Infected, do not harm the Survivors in any way. Unless there has been an update this has been confirmed to work on Crash Course in Versus. It is possible that it would work on other campaigns but Crash Course is much easier to complete as it is only 2 chapters.
  • Killing oneself in order to restart a chapter will not reset the status of this achievement. The campaign must be done from lobby to finale with no Special Infected damage taken.
  • Witches don't count as Special Infected for this achievement.
  • An easy way to get this achievement (only works on 360 Version) is to play campaign online with recommended of 1-3 other players and then do Chapters 1-4 on a campaign on any difficulty (Easy difficulty recommended) and when at the Finale don't open the safe room door (or it'll mess it up) and have everyone vote to return to lobby. When at the lobby the Host of the room changes the Chapter of the campaign you were doing to the Finale. Then when the game is started; this is when you can't take damage from Special Infected; so basically its only surviving the campaign on the Finale without any Survivors taking damage from Special Infected and not the whole campaign.
  • Another way to achieve this on the Xbox 360 is to get to the Runway Finale on Dead Air on Easy difficulty. Have the Survivors use two Assault Rifles and two Auto Shotguns (thus, the player should play as Zoey so her Bot AI doesn't use the Hunting Rifle). Clear all of the Infected, and stock up before activating the rescue. Run past the large aircraft parked in front of the C-130 Hercules plane, all the way until you are touching what appears to be police line tape. From there, the horde will primarily come from in front of the Survivors but have spawned from behind the tape as well as down the broken aircraft shaft to the right. Special Infected will spawn while on the tape but will not engage or advance to the Survivors with the exception of the Tank until you make your run back to the C130 during the escape. The first Tank will usually get stuck on the opposite side of the large aircraft making it an easy and relatively effortless target to down. The second Tank will come from just to the right of the large aircaft over a nearby truck. Keep in mind this tank will throw chunks of earth before reaching the Survivors. This method helps earn NOTHING SPECIAL and UNTOUCHABLES Achievements simultaneously. It may take several tries to accomplish this. As of 5 January 2011 the glitches in this method has not been patched.



L4d akimbo assassin AKIMBO ASSASSIN (30G)
Survive an entire campaign using only pistols.
  • You may use single or dual pistols. You can use environmental advantages but you cannot use primary weapons or the minigun.
  • In order to prevent accidental firing of a primary weapon, do not pick one up. This is especially useful after using a First aid kit, consuming pain pills, or being revived, as after these actions have finished, you automatically revert to selecting your primary weapon which could lead to accidental firing, especially during intense situations.
  • Molotovs and Pipe bombs can be used.
  • Use pistols to your advantage since when crouching they have very high accuracy and which they can take out Smokers or Boomers from quite a distance away.
  • When you are forced to fight a Tank or a Witch, let the bots take care of them. Stay out of the way and avoid engaging them, as the pistols are not powerful against either of them if they close in.
  • Although its original meaning is starkly different, dual wielding is sometimes called akimbo style.
  • An easy way to get this Achievement is to play through No Mercy on easy and stay low when a Tank spawns.
  • When playing online, make sure your team doesn't mind before you attempt this achievement. It's just common courtesy (and it will probably keep you from being kicked).
  • Another way to get this is to go on Single Player Mode and do it. AI primary fire will not mess up you getting this achievement. Only YOU have to survive the campaign only using pistols, not AI.
  • Grabbing a Primary Weapon, even if you never fire it, will result in you not getting the Achievement.


Versus ModeEdit

L4d double jump DOUBLE JUMP (20G)
Pounce two different Survivors in one life as a Hunter.
  • This is down mostly to the eventual lucky opportunity of being a Survivor using their melee attack to get you off a Survivor. You then need to get away without being killed. It works the best to wait for the Survivors to get separated; and then pounce on the lone one. As soon as they're dead, flee to avoid the other Survivors. The next time you pounce, you will get the achievement.
  • You can also pounce on a Survivor in a group and hope to be punted off without being shot to death afterward. Then simply step back and pounce again.
  • A double jump is a common skill in many video games, it allows a person to jump in the air.



L4d achievement cause x pounce damage JUMPIN' JACK SMASH (25G)
Pounce a Survivor for 25 points of damage in the Crash Course campaign.
  • Getting a 25 can sometimes prove difficult, however sticking to high places is the best place. Remember that the Hunter arcs in flight, so aim a little higher.
  • This is a reference to the song Jumpin' Jack Flash by The Rolling Stones.
  • This is a broken or glitched achievement on the Xbox 360 and will only unlock if playing a versus game on a local server (See Crash Course Campaign wikia page for information on forcing game into local server).
  • Easy way to do this, set up versus friends only with two controllers and bots (guest should be a survivor) and force game onto a local server. Grab the second controller and using the shot gun, incap and kill the three survivor bots. In front of the nose of the downed helicopter, there is a guardrail that looks almost like a border for the "safe area". Position the Survivor on the opposite side of the guardrail from the downed helicopter and towards the beginning of the guardrail. As an infected, you should start out as a smoker, run into the line of sight of the survivor and then switch controllers and kill the smoker. You will then spawn as a boomer and need to repeat what you have just done. You should now spawn as a hunter. Climb up to the roof of the warehouse behind the tail of the helicopter. There should be a chimney/smokestack that overlooks the "safe area." Climb on top and crouch. This next part will take some practice and correct judging. Since you are on the high ground, you want to set up the jump in order to land directly on the survivor at that height. If you aim directly at the survivor and jump, you'll come up short. You have to aim at a spot above a survivor. You should be aiming a little high than the skyline of the city off in the distance. If you arc it correctly, you should cause 25 points of damage and unlock the achievement.



L4d chain smoker CHAIN SMOKER (20G)
Constrict two Survivors in one life as a Smoker.
  • The strategy is largely the same as double jump. You need to hold on to the Survivors long enough to cause damage.
  • Stay on the rooftops. When someone is freed, back away from the roof edges to avoid gunfire. When the Survivors forget about you, constrict someone again.
  • A chain smoker is a person that has a habit of smoking multiple cigarettes in succession, usually one right after the other.



L4d big drag BIG DRAG (20G)
Drag a Survivor 100 feet with your tongue as a Smoker.
  • Spawn behind the group and nab the Survivor in the back. Eventually you will get lucky enough to have the Survivors not notice, and you will survive long enough to get the achievement.
  • This can also easily be done by hiding among the trees in the first section of Blood Harvest, as you will rarely be spotted before you grab a Survivor and long distances are abundant.
  • Pull a survivor right into a pipe bomb. The explosion will do good damage to your victim and also add distance to the pull.
  • Big Drag is a play on words, referring to both the act of dragging a survivor, and taking a drag from a cigarette.



L4d achievement drag biled survivor SLIPPERY PULL (25G)
Smoker pull a bile-covered Survivor until you hold him during Crash Course.
  • Once a Boomer pukes on any Survivor, simply pull him with your tongue and the achievement will unlock.
  • This Achievement is broken or glitched on the Xbox 360 and cannot be unlocked if playing on a dedicated server. It can be unlocked offline via system link or online using a local server (see Crash Course notes section for directions on forcing a versus game into a local server).
    • NOTE: Using system link is extremely difficult and not recommended.



L4d dead wreckening DEAD WRECKENING (20G)
Dole out 5000 total Survivor damage as a Special Infected.
  • Simply play versus long enough and you're bound to get it.
  • This achievement is a reference to the vehicle used in Land of the Dead by the mercenaries in the film. The vehicle's name was Dead Reckoning.
  • A way to get the Achievement faster is when you get the chance to play as a Tank try and bash out as much from the Survivors and try and incapacitate them and then go for the rest of them and you should get 25 damage per punch as a Tank.
  • The achievement title is a play on the term dead reckoning, which is a process for estimating the value of a variable quantity by using a previous value and adding any changes. It is commonly used in navigation for estimating one's position.



L4d barf bagged BARF BAGGED (20G)
Cover four Survivors with Boomer bile at once.
  • Exploding on Survivors doesn't count. You must vomit on all 4 in one attack.
  • Vomit on all four of the Survivors at once. If even one is missed, you will not get the achievement. One of the most important things to remember when trying to get this achievement is "location, location, location". If the Survivors are huddled into one corner, go for it.
  • Remember that if the Survivors are huddled too close, it will be tricky to hit the ones at the back of the group. Another tactic to avoid this situation is to look for an opportunity to ambush the Survivors when they are very slightly spread out, and spraying them all with bile in one horizontal motion.
  • A "barf bag" is a slang term for the air sickness bags provided on most airlines, intended for passengers that get sick during the flight to vomit into.



L4d all 4 dead ALL 4 DEAD (30G)
Incapacitate or kill all four Survivors in one life as a Tank.
  • This is down to your individual tactics.
  • Getting hit by a car instantly incapacitates a Survivor. If you can knock a car down a narrow hallway as all four Survivors are together, you can knock them all out in a single hit.
  • This achievement tends to be easier to get in the beginning of a campaign when the Survivors have only the pump shotgun and submachine gun, as they do much less damage to a Tank than the auto-shotgun, assault rifle, or hunting rifle that tend to be found later in a campaign, but obviously this depends on what items are spawned by the AI Director and in what location. Just keep playing Versus, hope you get to become a Tank early in the game, and just keep attacking and you can earn this achievement.
  • Although it's something that can be frowned upon normally, you can "steal" kills from team mates who have constricted or pounced players that are not yet incapacitated.
  • Note that as the Tank it is you that needs to incapacitate each survivor to earn this achievement, if you incapacitate three Survivors and a team mate incapacitates the last one you do NOT receive this achievement.
  • Likely a play on the phrase "One for all, and all for one." Could also be a reference to the game's title.



L4d lamb 2 slaughter LAMB 2 SLAUGHTER (20G)
As an Infected, incapacitate a Survivor who has entered and left a safe room.
  • This is down to your individual tactics.
  • It is possible that pouncing a Survivor as Hunter just as they close the door can earn you this achievement.
  • One of the easiest ways to do this is to wait outside the door after someone decided to go Rambo and run to the safe room without their teammates.
  • Another way to do this is use a Smoker to drag a Survivor out of the safe room and incapacitate him/her. You may have to choose a Survivor low on health to incapacitate him/her before other Survivors come.



L4d 20 car pile-up 20 CAR PILE-UP (20G)
As a Tank hit 20 Survivors with a car in the Crash Course campaign.
  • This achievement is cumulative, so it is not all in one game. The best place to get this will be the parking lot with the alarmed cars.
  • Dumpsters also affect the progress of this achievement.
  • On the Xbox 360: Hitting Survivors with a car does not count towards the achievement when playing on a local server. You must play on a dedicated server in order to receive credit. Interestingly, this is exactly opposite of the numerous broken versus achievements for Crash Course.
  • With a recent update, which restored lost achievement progress to players, many players received this achievement despite not having completed the requirements. The Crash Course campaign need not have even been downloaded for this to happen.



L4d achievement wipe all after truck TRUCK STOP (35G)
Your team wipes all Survivors after the escape vehicle has opened in Crash Course.
  • Simply incapacitate all the (remaining) Survivors after the escape vehicle appears in the Crash Course campaign. Probably easiest by being the Tank that spawns when the vehicle has arrived.



L4d achievement incapacitate 3 in 5 sec WIPEFEST (35G)
Your team incapacitates three Survivors within five seconds in the Crash Course campaign.
  • To earn this achievement you or your team 'simply' need to incapacitate 3 Survivors within 5 seconds of each other. The easiest way of achieving this is having a Tank incapacitate multiple Survivors in one go by hitting a car/forklift/object at them.
  • You must be one of the 3 Infected players incapacitating a Survivor player to be awarded the achievement.
  • You can get this achievement as a survivor using the following scenario (This is confirmed to work). Set up a versus friends-only game hosted on a local server using two controllers and bots (See Crash Course Campaign wikia page for explanation on forcing game into local server). Make sure the 2nd player guest is a survivor, and primary account is an infected. After the game has loaded, do not spawn as an infected. Using the second controller, do not leave the safe area. Grab the shot gun and shoot a survivor bot until they start to heal themselves. When a bot starts to heal him or herself, repeat the process with a different bot until all three bots have used their health packs. Now, shoot each survivor until their health is just above the point of incapacitation. Now, all you have to do is shoot the three bots and incap them all within 5 seconds and the achievement unlocks for the host account.


PC Exclusive PC only Edit

Survival ModeEdit

None of the Survival Achievements are present in the Xbox 360 version of the game since it is a free DLC.

L4d bronze mettle BRONZE METTLE
Earn a Bronze medal in Survival mode on any official level.
  • It is a pun on the word "medal" and "mettle".



L4d silver bullets SILVER BULLETS
Earn a Silver medal in Survival mode on any official level.
  • A common myth is that silver bullets are effective in slaying werewolves. Less common myths are that silver bullets will also kill or highly damage vampires and zombies.



L4d violence is golden VIOLENCE IS GOLDEN
Earn a Gold medal in Survival mode on any official level.
  • A play on words of the term "silence is golden."



L4d distinguished survivor DISTINGUISHED SURVIVOR
Earn at least a Bronze medal on every official Survival level.



L4d heroic survivor HEROIC SURVIVOR
Earn at least a Silver medal on every official Survival level.



L4d legendary survivor LEGENDARY SURVIVOR
Earn a Gold medal on every official Survival level.



L4D last stand LAST STAND
Complete one round of Survival on The Last Stand.


MiscellaneousEdit

Achievements that don't fit anywhere else.

L4d outbreak OUTBREAK
Catch a rare strain of infection, then pass it on to someone else.
  • This is unlocked by being vomited on by a player-controlled Boomer who already has this achievement, while in Versus
  • This achievement originated from Boomers controlled by Valve developer players.


Left 4 Dead 2Edit

CampaignEdit

Price chopper PRICE CHOPPER (20G)
Survive the Dead Center campaign.
  • This can be acquired by completing the campaign on any difficulty.
  • "Price Chopper" refers to the setting of the campaign (in a mall) and the use of newly introduced close combat weapons.
  • "Price Chopper" is also the name of two grocery store chains in the United States. One is headquartered in upstate New York, and the other is headquartered in Kansas City.



Torch-Bearer TORCH BEARER (20G)
Survive The Passing campaign.
  • This can be acquired by completing the campaign on any difficulty.
  • "Torch Bearer" refers to a legacy being passed on (a.k.a. "passing the torch"); the original four Survivors' journey may very well have come to an end, which coincided with the new Survivors meeting them and continuing on their own journey.



Midnight rider MIDNIGHT RIDER (20G)
Survive the Dark Carnival campaign.
  • This can be acquired by completing the campaign on any difficulty.
  • The achievement name is a reference both to the term "midnight rider" (a person who visits an amusement park late at night) and to the fictional in-game band, The Midnight Riders.
  • The achievement, as well as the band's name, is more likely a reference to the Greg Allman song, "Midnight Rider," as the song can be fairly easily interpreted as about someone running from some fate the singer is afraid of. The obvious parallel to the Survivor position in the game setting is perfect.



Ragin cajun RAGIN' CAJUN (20G)
Survive the Swamp Fever campaign.
  • This can be acquired by completing the campaign on any difficulty.
  • Cajun refers to both an ethnic group and cuisine that are common in the area in which the game is set.
  • Ragin' Cajun is a common pun in the Deep South. There is a restaurant chain called the Ragin' Cajun, and several sports teams. James Carville, chief campaign strategist for the Clinton campaign of '92, was nicknamed the Ragin' Cajun.



Weatherman WEATHERMAN (20G)
Survive the Hard Rain campaign.
  • This can be acquired by completing the campaign on any difficulty.
  • This campaign features torrential rain and extreme weather resulting from an approaching hurricane.



Bridge burner BRIDGE BURNER (20G)
Survive The Parish campaign.
  • This can be acquired by completing the campaign on any difficulty.
  • The campaign finale involves the Survivors crossing a two-level bridge being bombed by F-18 Hornets.



Streamcrosser STREAM CROSSER (20G)
Survive the Cold Stream campaign.
  • Currently only available for the PC version.
  • This can be acquired by completing the campaign on any difficulty.
  • In practice, it is actually awarded for playtesting the beta version of Cold Stream.


SurvivorEdit

Still something to prove STILL SOMETHING TO PROVE (35G)
Survive all campaigns on Expert.
  • The name is a reference to the Left 4 Dead achievement What Are You Trying To Prove?, which also involved surviving all the campaigns on Expert.
  • Beating Expert in a DLC campaign does not count.
  • Surviving a campaign on Realism Mode with Expert difficulty adds to the count of this achievement. (ex. you're 0/5 on this achievement and you survive a campaign on Realism Mode with Expert would make this 1/5).
  • Beating the mutation mode Last Man on Earth on Expert will give you this achievement. With surround sound and good coordination, you should be able to beat campaigns in average of about 30 minutes each.
  • Can be completed in less time through the "Room for One" mutation; note, you do not have to be the one who gets on the rescue vehicle in order to gain credit for this achievement, all that matters is that you are not dead nor incapacitated.
  • Gib Fest is a great Mutation for getting this Achievement and it is made much easier by playing alone with three Bots as they cannot deal friendly fire damage to you. Plus they have faster reaction times when spotting Infected along with notable sight. Always try to avoid Witches and keep an Adrenaline shot at all times for fighting the Tank, which is much easier to kill than you would expect with the M60s.
  • When trying to get this achievement with a Mutation, remember that you first need to start a normal game on Expert difficulty, then quit and launch the Mutation through the console(see the Mutations article for details). The Expert difficulty will then "carry over" from the previous game. Running the Mutation on non-Expert and then changing the difficulty in-game will NOT count.



The real deal THE REAL DEAL (35G)
Survive a campaign on Expert skill with Realism mode enabled.
  • Dead Center is probably the easiest way to get this achievement, since it is (more or less) the shortest. Expect a hell of a time with the mall and the gas can finale, though.
  • Contrary to popular belief, the white auras around the gas cans still show up in the Realism finale of Dead Center. They do, of course, vanish when your teammates pick them up, but the yellow auras will appear when the gas can is dropped.
  • If the Scavenge mode finale puts you off, Hard Rain may be another option as there are no gauntlet crescendo events. Yet another possibility is Swamp Fever, which also doesn't contain gauntlet crescendo events; however, the second wave at the Finale consists of two Tanks. Swamp Fever is also better choice if you play with bots, because it's hard to keep them alive in the Sugar Mill.
  • A very easy way to get this, is to skip to the finale (assuming it's Dead Center), leave the game and let your teammates do the finale and when they only have one gas can left, tell them to change difficulty to Expert, and join the game, run to the vehicle and you should get it. Why this is because it says to "survive" Expert Realism, you finished it, aka: survived to the end even if it was a short time (tip: save Bile bombs to use while the player is joining the game, and to protect Survivor Bots). Also it seems this only works on the Xbox 360 version of the game.
  • An even easier way to get the achievement is to kick the special infected with console commands if you created the server. This, however, is unfair and could take the fun out of the game. You have to type "kick [name of special infected]" without the "", for example: "kick tank". There is no need for "sv_cheats 1".



Confedaracy of crunches CONFEDERACY OF CRUNCHES (30G)
Finish a campaign using only melee weapons.
  • Refers to the book A Confederacy of Dunces by John Kennedy Toole which also takes place in New Orleans.
  • Shooting a Pistol while incapacitated stops you from getting this achievement.
  • Using the Heavy Machine Gun, Pipe bombs, Bile bombs and Molotovs does not count against this achievement.
  • The Passing is probably the best campaign for this achievement, since it's the shortest and three extra Survivor Bots will help you during the finale.
  • You can also start in Single Player on Easy and only pick up a melee weapon. The bots are allowed to shoot with any guns.
  • It is also possible to earn this by joining in after the AI has shot any amount of rounds.



Head honcho HEAD HONCHO (15G)
Decapitate 200 Infected with a melee weapon.
  • When using the melee weapon, aim around the height of Common Infected head to decapitate them and count toward this achievement.
  • Using the Crowbar may also work as it may decapitate Common Infected's head, but mostly takes only part of the head off, not all of it.
  • The Frying Pan and Nightstick cannot be used to earn this achievement as they can't decapitate Common Infected.
  • Using the Chainsaw can also earn this achievement but is quite difficult, as its attacking speed is too high, and the only area that counts is on the neck.
  • Despite the achievement's description, it is still possible to achieve it with gore disabled.



Club dead CLUB DEAD (15G)
Use every melee weapon to kill Common Infected.



Chain of command CHAIN OF COMMAND (15G)
Kill 100 Common Infected with the chainsaw.
  • You can get a lot of credit towards this during gauntlet events, particularly the one at the end of The Barns.
  • Make sure your team knows that you're planning to go nuts with a Chainsaw if you're not playing on Easy. It can be a very sloppy weapon, resulting in lots of friendly fire.
  • The name is a reference to a military term describing ranks tied in with the pun of Chainsaw.



Tank burger TANK BURGER (30G)
Kill a Tank with melee weapons.
  • The Tank can only take melee damage for this to count, for anybody; no one can shoot or burn it otherwise the achievement will not be obtained.
  • This is easier to do if your entire team uses melee and at least one person has a Chainsaw.
  • As long as the Tank is killed using only melee weapons, every Survivor gets this achievement, regardless of if they dealt any damage to the Tank or not. It is possible (although rare) for three AI Survivors to melee a Tank to death by themselves, giving the player the achievement for no effort.
  • As a rescue vehicle arrives in any finale, kill the AI and hit the Tank once then jump on the rescue vehicle. The Tank dies automatically and it counts as your kill.
  • This is likely to be a glitch, but if the Tank is completely avoided (which is unlikely, except in the Bridge Finale), no damage or only melee damage is done, when the Survivors escape/reach the safe room, all players who haven't yet will get this achievement. It has been confirmed on the Xbox 360, and it unlocks right when the rescue vehicle is leaving. But make sure the AI Survivors are dead, or incapacitated far away and can't see the Tank.
  • The title is a reference to the restaurant chain in the Left 4 Dead world, Burger Tank (More likely the act of beating a tank with melee weapons would "tenderize" it to look like a hamburger).
  • It is easiest to obtain on the Mutations Chainsaw Massacre and Four Swordsmen.
  • Not obtainable through the TAAANNNKK!! mutation.



Shock jock SHOCK JOCK (30G)
Revive 10 dead Survivors with the defibrillator.
  • If you want to get this achievement quickly, play the first chapter of Dead Center and find at least one Defibrillator (obviously, it's easier to get more if you have human team members). Play the level normally until you reach the safe room, then switch the difficulty to Expert and let at least one of your team members die, then switch back to Easy, clear out the Infected, and defibrillate away. From there, you can get someone else killed if you had more than one Defibrillator, or restart the chapter to do it again.
    • This may also be easier playing the Bleed Out mode of Mutation since only Defibrillators spawn and deaths are rather common.
    • Note that reviving the same person more than once in a single session won't count toward the achievement. Restart the chapter before getting the same Survivor killed again.
    • There tends to be a larger number of defibrillators in Hard Rain than other campaigns, making it a good choice for earning this achievement quickly.
    • Killing a Survivor and then using the Defibrillator on them does not count towards the score. The Infected have to do it for you.
      • Having a Survivor bleed out after you incapacitate them, however, does not count as you killing the Survivor.
      • Pushing an AI survivor into a fire (such as near the end of Dead Center's "Hotel") and then defibrillating them does count as achievement progress, this also works for "The Quick and the Dead".
    • If the Survivor falls to their death or dies from fall damage it still counts.
  • Shock jock is a slang term used to describe a type of radio broadcaster or disc jockey who entertains listeners or attracts attention using humor and/or melodramatic exaggeration that a notable portion of the listening audience may find offensive.



The quick and the dead THE QUICK AND THE DEAD (30G)
Revive 10 incapacitated Survivors while under the speed-boosting effects of adrenaline.
  • Simply take any Adrenaline Shot you see and save it for an incapacitated Survivor.
    • Incapping a Survivor then reviving them while under the adrenaline's effect does not count toward the achievement.
    • Pulling a Survivor from a ledge will count. Start Hard Rain's Sugar Mill or Mill Escape, and get to the top of the empty building (just before/after the plantation), and make sure you have at least one Adrenaline Shot. The Survivors can just walk towards the precipice, and with adrenaline, lift them up.
    • Another easy method of achieving this is to do Mall Atrium on Survival and continually let someone drop on a high ledge. If done right you can get about three revives with one Adrenaline shot.
    • Pushing a Survivor Bot into a fire (such as near the end of Dead Center's "Hotel") and then reviving them does count as achievement progress, this also works for "Shock Jock".
  • "The Quick and the Dead" is a phrase from the King James version of the Bible, and has been the title of several movies.



Armory of one ARMORY OF ONE (15G)
Deploy an ammo upgrade and have your team use it.
  • Find an ammo upgrade and deploy it some where near the Survivors and hopefully they should notice but if there are troubles with it, go on single player and do it with the bots as they should all pick up the upgrade after it is deployed.
  • Armory of One is a pun on the US Army slogan "An Army of One".



Burning sensation BURNING SENSATION (15G)
Ignite 50 Common Infected with incendiary ammo.
  • This can easily be earned by combining incendiary ammo with a shotgun (preferably an Auto Shotgun) during a horde. Because of the wide spread, it ignites them instantly.
  • This is painfully easy when you combine a M60 with the upgrade, especially in the Mutation Gib Fest, as it gives you 150 bullets (assuming you haven't wasted any of it yet or are in Gib Fest). This means that you can miss on average two of every three shots and still get this in one playthrough.



Dismemberment plan DISMEMBERMENT PLAN (20G)
Kill 15 Infected with a single grenade launcher blast.
  • This achievement can be earned by throwing a Pipe bomb or a Bile bomb on the ground during a horde and simply shooting in the middle.



Septic tank SEPTIC TANK (15G)
Use a bile bomb on a Tank.
  • Self-explanatory. You usually have to be pretty close to the Tank to reliably hit it with a Bile bomb, so be ready to act fast.
  • The Bile Bomb has to hit the Tank directly, hitting the ground, walls, or other Infected does not count.
  • A septic tank is a sewage-disposal container, usually positioned below ground, in which a continuous flow of waste material is decomposed by anaerobic bacteria.



Crass menagerie CRASS MENAGERIE (20G)
Kill one of each Uncommon Infected.
  • It is not required to kill a Riot Infected in The Parish, despite being portrayed in the achievement image.
  • The achievement title is a reference to the play The Glass Menagerie by Tennessee Williams, which is set in New Orleans.
  • You do not have to kill Jimmy Gibbs Jr. infected to earn this achievement.



Dead in the water DEAD IN THE WATER (20G)
Kill 10 swampy Mudmen while they are in the water.
  • If you toss a Pipe bomb into the water during a horde, you will get a lot of progress to this achievement at once.
  • The achievement title is a nautical term used to describe a vessel that can no longer function or move. It is often applied metaphorically to describe anything with a similar circumstance of immobility.



Robbed zombie ROBBED ZOMBIE (15G)
Collect 10 vials of Boomer vomit from infected CEDA agents you have killed.
  • This achievement can be harder than it may sound, considering CEDA Worker Infected have only a 5% chance of spawning, only one in ten of those will have a Bile bomb, and they only spawn in The Hotel and The Streets.
  • You do not need to actually kill the CEDA Worker Infected, just pick up the Bile bomb he drops and use it for it to count towards this achievement.
  • The name is a reference to the musician and horror filmmaker, Rob Zombie.
  • An easy way to get this if you have a bile bomb (assuming you have killed some towards the achievement) simply throw one away, then pick up the next.



Cl0wnd CL0WND (15G)
Honk the noses of 10 Clowns.
  • The name is a reference to the Left 4 Dead achievement CR0WND.
  • Melee shoving a Clown Infected in the face will honk its nose.
  • You can hit the same Clown Infected more than once for progress towards this achievement.
  • In the German and French descriptions for this achievement, for unknown reasons, it's told to KILL 10 Clowns, but you still have to honk the nose.



Fried piper FRIED PIPER (15G)
Using a Molotov, burn a Clown leading at least 10 Common Infected.
  • During a horde, throw a molotov into the groups of swarming infected; odds are there's at least one Clown in there.
  • Fried Piper is a play on the legend of the Pied Piper.



Level a charge LEVEL A CHARGE (15G)
Kill a Charger with a melee weapon while they are charging.
  • The Charger has 600 HP, and a melee hit does 300, so someone will need to shoot the charger a few times for this to be done properly.
  • This is a hard achievement to earn naturally. Ask your team to let you walk in the front, and to shoot a few bullets at all Chargers but not enough to kill them, in order for you to be able to melee them when they charge. It is almost impossible to get this achievement with bots, as they will either shoot the Charger too little or too much for you to kill him while he charges.
  • The Last Man on Earth mutation is the perfect opportunity to earn this achievement. Just kill any other special infected and you'll be facing the charger alone with no bots, teammates or common infected to get in your way.
  • To level a charge means to accuse someone of some crime or misdeed.



Acid reflex ACID REFLEX (15G)
Kill a Spitter before she is able to spit.
  • It is easy to spot Spitters from far away because of their neon green drool. Spitters almost always run for cover as soon as you spot them, so crouch for improved accuracy and fire quickly. Remember that you can shoot through most thin walls, so if a Spitter ducks into a doorway, spray the wall in front of it with lead.
  • Shares name with a Half-Life 2: Episode 2 achievement. The achievement title is a play on the term "acid reflux", which itself is a colloquial name for Gastroesophageal reflux disease (GERD). GERD is a condition in which the stomach contents (food or liquid) leak backwards from the stomach into the esophagus, causing heartburn and other symptoms.
  • Killing a Spitter that hasn't used their primary attack in Versus Mode will count towards this achievement.
  • Over 80.6% of the players on Steam have this achievement, like Drag and Drop. It is thus the most common achievement according to Steam statistics.



A ride denied A RIDE DENIED (15G)
Kill a Jockey within 2 seconds of it jumping on a Survivor.
  • It is easiest to shoot the Jockey with an Tier 2 shotgun to deal the most damage.



Stache whacker STACHE WHACKER (15G)
Prove you are faster than Moustachio.
  • You must get a total score of 42 on the Whack-A-Mole game in Dark Carnival, which is in the 4th level.
    • Every player who whacks at least one Moustachio will get the achievement. Doing this will trigger a horde.
  • This can be done in Survival.
  • The score is possibly referring to the title of the game, Left 4 Dead 2.
    • Or it is a reference to 42 in Hitchhiker's Guide to the Galaxy, in which the number 42 is the answer to the ultimate question of life, the universe, and everything.



Gong show GONG SHOW (15G)
Prove you are stronger than Moustachio.
  • You must use an Adrenaline Shot and a melee weapon on the Strong Man game in Dark Carnival's fourth section. Be ready to fight a horde right afterwards.
    • It does not matter what melee weapon you choose to execute this achievement.
  • This can be done in Versus.
  • A Tank can hit the pad and successfully break the gong. You won't get the achievement for breaking the gong that way.
  • The Gong Show was an American television program from the 1970s in which marginally-talented contestants performed various stage acts that were then judged by a panel of D-List celebrities from the era. If a contestant was particularly bad, the act would be interrupted by someone on the panel banging a huge gong behind them on the set.

This may also be a play on words "Gun Show" where a person who has muscles flexes. This can be inferenced from having to be "stronger", and strong people usually have muscles.



Guardin gnome GUARDIN' GNOME (30G)
Rescue Gnome Chompski from the Carnival.
  • The title is a play on the words "Garden Gnome".
  • "Gnome Chompski" is a play on the name of the political writer "Noam Chomsky".
  • The gnome can be found on the shooting gallery in the second chapter of Dark Carnival. Push the button and score 750 points by shooting the targets. The box to the left of the gallery will open and the gnome can be picked up. From now on, you have to carry him through the entire campaign and carry him to the rescue helicopter with you, holding on to the Gnome until the closing cutscene.
  • The Achievement is a reference to Half-Life 2: Episode 2's achievement "Little Rocket Man". The player had to carry the gnome from the first level to the last level of the game and fire it into space by putting it into a rocket.
    • The Gnome uses the same model and textures as in Half-Life 2: Episode 2, with only slight changes on bump-maps and the size of the model itself.
  • Even Survivors who don't make it onto the helicopter will get this achievement as long as the gnome and at least one Survivor escape.
  • Sometimes the gnome just disappears or falls through doors. So make sure you keep an eye on it.
  • Even if you drop the Gnome in the very middle of the tracks on the Roller Coaster Crescendo, it will sometimes fall through.
  • A good strategy is to toss Gnome Chompski over the fence near where you start the Roller Coaster. This way, you can run the majority of the roller coaster unencumbered, and come back to retrieve him after you've stopped the alarm.
  • This achievement is actually quite easy to obtain via the "Last Gnome on Earth" Mutation. One can even start the game at "The Concert" on Easy and the achievement will be unlocked when the survivors escape with the gnome.



Wing and a prayer WING AND A PRAYER (30G)
Defend yourself at the crashed airliner without taking damage.
  • To do this achievement, start in Swamp Fever chapter 2, Swamp. Grab an automatic weapon from the safehouse. Next, go through the level, make sure you pick up a few throwables on the way. When you get to the crashed aircraft, trigger the event and dash back to the area with the shed and the campfire. There is almost always an ammo pack there. All the Infected, including the Special variety, will spawn in front of the plane, letting the Survivors all focus on one direction. In this sense, one can simply throw a Molotov or the like and watch all the zombies run directly into the fire.
  • An alternative method would be to camp in an area just to the right, slightly behind, the plane. It takes Infected a while to get to the Survivors, and some don't even make it. Just throw bile or a Molotov ahead, and if you need extra protection, have someone stand ahead and take care of Infected that could cause problems (Such as Chargers and Spitters) and draw the full attention of Commons towards them.
  • This is NOT a party achievement. To be more specific, the only person whose health must not decrease during the event is the person attempting to get the achievement. Using adrenaline or pills will make this achievement impossible, as the health lost over time counts as damage. Taking friendly fire - even if no change shows in the health bar - will also stop you from getting this achievement.
  • By far the easiest method to complete this in single player is, in fact, to stay inside the plane. Arm yourself with a melee weapon, and preferably a bile bomb or pipe bomb, then simply trigger the door and walk "down" the plane (towards where the tail would be, with the emergency door on your left) and slip in to the left behind the last row of seats you are able to get behind. The infected will not come in behind you, and the AI Survivors will take all the heat off of you. Alternately, go towards the forward part of the middle section and use the C-shaped hole where the window seat is missing from the forward row, and focus your attention forward. However, Spitters can cause damage if they spit in the correct area, and a Smoker might ensnare you behind the plane.
  • An easy way to get this achievement on the Xbox is to simply use two controllers. Leave the player who is trying to get the achievement in the safe room while the other player goes and activates the event. As long as you stay inside the safe room and be sure not to take any damage, you will get the achievement.



Sob story SOB STORY (30G)
Navigate the sugar mill and reach the safe room without killing any Witches.
  • Keeping your flashlight off during the entire time spent in the sugar mill and being more alert than usual goes a long way. Back off immediately into the direction you came from if a Witch starts to growl; this is often enough to avoid fighting them. Note that you CAN use Boomer bile to kill Witches and still get this achievement - you just need to be far enough in order for a Witch not to register that you have attacked her. You can't, however, get enough bile to kill all the Witches discreetly on the level, so be prepared to sneak in order to get this achievement.
  • If you disturb a Witch, it is still possible to receive this achievement. This can be accomplished as long as the Witch isn't killed. Generally, this means allowing her to kill the disturber, though driving her off with heavy fire works too. Everyone who enters the safe room will receive this achievement upon entry. Grab a defibrillator, and return to revive your team mate, since Witches cannot be driven off reliably on any difficulty.
  • A pretty easy way to get this achievement (Requires Cold Stream DLC) is to choose the mutation "Last Man on Earth" and start directly at the Sugar Mill on Easy. Bots won't be startling Witches and Common Infected won't spawn, making the level (almost) a walk in the park aside from the occasional Special infected and again, the Witches.
  • A sob story is a sad tale, especially one intended to elicit sympathy for the teller.



Violence in silence VIOLENCE IN SILENCE (30G)
Navigate the impound lot and reach the cemetery safe room without tripping any alarms.
  • The achievement can be obtained, even if teammates trigger the alarm
  • This achievement is best done by using melee weapons only in the impound lot and with human players. If you don't have any human players, kick the bots by using console command "kick [name of bot]" (X360 players will have to grin and bear it or kill off the bots).
  • This can also be easily obtained through the "Last Man on Earth" mutation, as since no bots are present (nor Common Infected), accidental alarm-sounding is highly unlikely.
  • Having a Tank spawn in the impound lot can actually be a blessing in disguise; the Tank may punch the cars with alarms out of the way while you and your teammates retreat to the sewer, therefore avoiding the cars from incapping you.
  • The name of this achievement may be a reference to the Depeche Mode song "Enjoy the Silence" with its lyrics "Words like violence break the silence...".



Bridge over troubled slaughter BRIDGE OVER TREBLED SLAUGHTER (30G)
Cross the bridge finale in less than three minutes.
  • This is reference to the Simon and Garfunkel song "Bridge Over Troubled Water".
  • Trebled means "three times", referring to the number of minutes you have to cross the bridge.
  • Try to keep left: Infected tend to bunch up near this area, giving you less need to shoot aimlessly.
  • The best loadout to get this achievement would be a melee weapon and an automatic weapon such as a Tier 2 rifle or shotgun.
  • Note that this achievement requires the ending to trigger in under 3 minutes from the start of the bridge finale. Killing off any bots is advised.
  • In order to make it in time, you'll have to skip the Tank. Have him distracted by the cars, take adrenaline, and rush over the tanker, across the last strip of bridge, and onto the chopper.
  • If you start the finale on Expert, kill the bots, then switch to Easy and you can complete this achievement alone without worrying about slower teammates holding you back.
  • This can also be obtained even easier through the "Last Man on Earth" Mutation. Since only Special Infected spawn and no cumbersome AI players follow, keeping left and constantly running will mean the Tank is the only problematic encounter (who can be easily out-ran through use of a Molotov and Adrenaline).
  • Another good way to earn this achievement is by playing the Room for One Mutation, even in single player. Although Common Infected will spawn, the AI bots will help you, killing from behind (no friendly fire!) any Common and Special Infected (with smaller spawn rate than Last Man on Earth) that harass you. As you don't need to wait for them (they will probably stop to kill a Spitter or the Tank), you can calmly leave them behind and get the achievement.



Fore FORE! (25G)
Knock off the heads of 18 infected with the golf club.
  • The name of this achievement is a reference to the word commonly called out when swinging a club to alert people to watch out for the golf ball.
  • The 18 headshots required references the number of holes in a standard golf course.



Til-it-goes-click TIL IT GOES CLICK (20G)
Using the M60, kill 25 infected without letting go of the trigger.
  • An easy way to get this is by using the M60 in The Sewer Crescendo. At the last tunnel (before you reach the ladder to the safe room), a Horde will always spawn, and is perfectly lined up for you to mow down.
  • Another way to get this is to play a survival map on any level of The Passing, as an M60 will always spawn, and you can easily mow down the never ending Hordes.
  • It can also be used in conjunction with a Bile Bomb to attract a horde of Infected, and you can simply mow them down.
  • Contrary to the name of the achievement, you do not have to hold the trigger 'til it goes click' to get it, unless you happen to run out of ammo around the same time that you obtain the achievement.
  • It is easy to obtain this achievement while playing the Gib Fest Mutation. As the M60 has unlimited ammo, simply hold down the trigger indefinitly until 25 Infected are killed.
  • This achievement refers to a line spoken by John Turturro's character in the movie The Big Lebowski: "I'll take it [the gun] away from you, stick it up your ass and pull the f***ing trigger till it goes 'click'."



Killing-Them-Swiftly-To-This-Song KILLING THEM SWIFTLY TO THIS SONG (20G)
Play the new Midnight Riders song on a jukebox.
  • Alludes to the 70s hit song "Killing Me Softly With His Song" originally sung by Roberta Flack and covered in 1996 by The Fugees.
  • One of the jukebox can be found on the Final Stage of The Passing on the ground floor of the House where the original Survivors snipe from.



Kite-Like-a-Man 2 KITE LIKE A MAN (30G)
Kill a tank only with damage from the original Survivors.
  • "Kiting" is a common MMORPG tactic in which a player holds the attention of a boss and proceeds to run away without the intention of escaping, similar to running from a Tank, but staying close enough to keep it from switching targets.
  • The title 'Kite Like A Man' is a play on words with the term 'fight like a man'.
  • This achievement is possible in single player, although it somewhat relies on luck. If you and the bots are far from the generator and a Tank spawns there, the original Survivors may be able to kill it, as Louis can quickly kill it with his Heavy Machine Gun. This is more easily done, however, with three other human players, or by killing any bots.
  • A simple way to do this (even on single player) is to wait at the bridge (after the generator has already been activated) until a tank spawns. As soon as you have an indication that it has spawned, run to the car before any of the Left 4 Dead 2 Survivors can shoot it. Once the ending is triggered, it should give you the achievment, even if the originals haven't killed it yet. This is because the Tank dies automatically upon ending the campaign.
  • If you are unsure of whether or not a tank will spawn, simply kick all other bots on the team and tell all human survivors to cease fire, then take out a melee weapon and hide near Louis. Wait out the horde until the Tank arrives. He usually will spawn either very far away, or behind the fence. Either way it will take him a long time to reach you. Staying near Louis means that you have the strongest of the Left 4 Dead survivor-mounted weapon on your side, and on easy will shred the tank in no time. If the tank does close the gap, circle around the building to buy you some time and to let the bots whittle his health down.
  • The Lone Gunman mutation might be the best opportunity to earn this achievement, as there are no other teammates to damage the tank and boomers are the only special infected.
  • Another simple way is when a Tank comes and then hide at the second floor of the house with the bar and jukebox. Make sure it is at a far distance or else if it is near, the 3 original survivors won't have all the time to kill it and then it can easily go through the door.



Grave-Robber GRAVE ROBBER (25G)
Collect 10 items dropped by a Fallen Survivor.



Cache-Grab CACHE GRAB (20G)
Open 5 foot lockers.
  • There are Foot Lockers scattered throughout The Passing that contain a cache of unlimited items. Simply be the first one to open them.
  • The achievement title is a play on the phrase "cash grab" which is a derogatory term for a cheap, substandard quality product produced simply to make money.


Adversarial ModesEdit

VersusEdit

0456c61b83feb90ce2a2d0765b1ecf8671396085 CONNECTING FIGHT (??G)
Play a Realism Versus game on Dead Air from start to finish.
  • This achievement can be earned by playing a whole game of Realism Versus without quitting the game, win or lose. You must play the game starting from the lobby, not merely joining in during the first round.
  • The prerequisite needed to earn this achievement addresses the issue of rage quitting, an action in online games where a player quits the game prematurely, mainly due to losing. This achievement encourages people to not quit before the game has ended.
  • The title refers to the very simliar sounding term "connecting flight" which is when a person flies to one location and takes another plane to another location, connecting the flight. This also refers to how both teams in Versus switch sides as they play, thus, connecting to a different "flight".
  • Valve states that they will release a beta version of Blood Harvest for Left 4 Dead 2 if at least 60,000 players earn this achievement.


SurvivorsEdit

Heart warmer HEARTWARMER (20G)
In a Versus round, leave the safe room to defibrillate a dead teammate.
  • This cannot be earned if a human Survivor kills a player outside of the safe room, run in and out, and then revive them. An infected player needs to kill the Survivor.
  • Throughout levels, always try and take a defibrillator, and if possible near the safe room (if there is no horde and your team is doing well), send out your teammate with the lowest health to die at the the hands of the infected, run in and out and defib him/her.
  • According to Guinness World Records Gamer's Edition 2012 only a mere 2% of players that have purchased Left 4 Dead 2 have obtained this achievement.



Strength in numbers STRENGTH IN NUMBERS (15G)
Form a team and beat an enemy team in 4v4 Versus or Scavenge.
  • Since team games are unpopular and lobbies are much quicker to use, you will probably have to organize a game with friends.



Gift-grab-2011 VALVE GIFT GRAB 2011 - L4D2 (N/AG)
Collect three gifts dropped by Special Infected in Versus Mode.
  • These gifts were dropped by random Special Infected during the holiday sales on Steam that ran through the last several weeks of December 2011 and December 2012. This achievement can not be obtained outside of holiday times, and was only available on the PC and Mac versions of the game for the duration of the holiday sale. This achievement was one of many that were introduced to various games on Steam as part of the promo for the sale and, in December 2011, like most of these achievements, gave a piece of coal or a coupon to each player who achieved it.



Nick achieve GOOD GUY NICK - L4D2 (N/AG)
Play in a campaign with free-to-play players from beginning to end.
  • Only available during any period where the game is Free to Play, such as the Halloween season on Steam that ran through the last couple of weeks in October 2012, and the Independence Day season that lasted through the weekend of the Fourth of July in 2013. This achievement could only be obtained on the PC, Mac, and Linux versions for the duration of those weekends.


InfectedEdit

Qualified ride QUALIFIED RIDE (15G)
As the Jockey, ride a Survivor for more than 12 seconds.
  • You need to attack a Survivor that is in good health (has a green aura) in order to be able to ride for more than 12 seconds. It is also necessary to ride someone separated from the rest of the Survivors, in order to make sure your ride is not cut short. Scavenge games often have separated Survivors and are ideal to earn this achievement.
  • On The Highway, wait till about 3 Survivors jump down the hill, then pounce on the fourth and ride him back into the motel. There will be nothing the other Survivors can do about it. Alternatively, jump on the first survivor down the hill and steer him far away. It will take some time for the others to reach him, which will usually give you enough time to obtain this achievement.
  • The name of this achievement refers to bull riding.



Back on the saddle BACK IN THE SADDLE (15G)
As the Jockey, ride the Survivors twice in a single life.
  • An easy way to do this is to wait until a Survivor is in red or can be incapacitated quckly i.e. low health and pounce that Survivor. Down them and run and hide for cover from the rescuing teammates. Once you can pounce again, attack any Survivor and you will unlock it.
  • The Mutation Riding my survivor is an excellent game to get this achievement as all 4 infected players are jockeys.
  • "Back in the Saddle" is also the name of a song by the band Aerosmith.



Rode hard put away wet RODE HARD, PUT AWAY WET (20G)
As the Jockey, ride a Survivor and steer them into a Spitter's acid patch.
  • This achievement is easily obtained with coordination from a Spitter player. You do not actually have to steer a Survivor into the acid; it is enough if a Spitter spits at you. Either way is fine; making this achievement easy.
  • Shares name with a Team Fortress 2 achievement.
  • There is a glitch that allows this achievement to be done if you drive your victim into a molotov fire. (Not tested on PC.)
  • This achievement cannot be earned if your target was already in Spitter acid, unless you take them out of the acid and then back in.
  • The name of the achievement is a regional expression to describe someone who looks haggard or worn-out; it originally was said of horses.



Great expectorations GREAT EXPECTORATIONS (15G)
As the Spitter, hit every Survivor with a single acid patch.
  • If the Survivors are cornered or are in a tight area, attempt to spit at them. This achievement will NOT unlock if they aren't hit with a single hit; they must all be standing in the acid pool when it forms.
  • Despite showing up in the in-game achievement list as "Great Expectorations", the pop-up box that appears when you earn the achievement and the "X achieved Left 4 Dead 2:" messages in the Steam Community window both list this achievement as "Spit Happens".
  • An expectoration is the act of spitting up sputum.
  • "Great Expectations" is a novel by Charles Dickens.



A spittle help from my friends A SPITTLE HELP FROM MY FRIENDS (15G)
As the Spitter, spit on a Survivor being choked by a Smoker.
  • The achievement title is likely a reference to the song With a Little Help from My Friends by The Beatles.
  • This achievement is very simple: During Versus or Scavenge, spit at someone grabbed by a Smoker and the achievement is yours.
  • If a Smoker tongues a Survivor while standing on a ledge higher than its target, the Survivor will be suspended in midair just above the ground. In this position, a Survivor will still take damage from an acid puddle, and the achievement will still unlock.
  • If you are standing next to a choked Survivor and die without spitting, the acid from your dead body will count towards the achievement.
  • This achievement may take a few seconds to register after spitting on the victim.



Scattering ram SCATTERING RAM (20G)
As the Charger, bowl through the entire enemy team in a single charge.
  • The name is an obvious pun of the term "battering ram".
  • A good place to do this is in the gauntlet event at the end of The Park. Once all the Survivors have climbed to the top of the scaffolding, climb up after them. They have no room to dodge and you should charge through all of them to the end of the platform (also earning Long Distance Carrier in the process).
  • Another good spot is in the sewers area on the next chapter; If you charge successfully any survivor down there has virtually no where to run.
  • A third spot is at the immediate beginning of Dead Center, the Hotel; if the Survivors decide to shoot at CI through the first door, you can spawn in the starting area, jump down and ram into them, hopefully they will be bunched up enough to do this.
  • Another good way to earn this achievement is to play the final level of the Dead Center campaign. When the Survivors enter the elevator, you can spawn on the ground floor and ram them all when the elevator doors open.
  • It is also possible to earn this achievement on servers modded for 8v8; only 4 Survivors need to be hit in order to unlock.



Meat tenderizer MEAT TENDERIZER (20G)
As the Charger, grab a Survivor and smash them into the ground for a solid 15 seconds.
  • This is easiest to do during a Scavenge match on the last standing Survivor. The time sent pounding while the scoreboard is showing counts toward the achievement.
  • An odd thing in the achievement picture is that the Charger's left arm is his bulky one as opposed to his normal right arm.
  • A meat tenderizer refers to either a kitchen utensil or a chemical used for tenderizing meat.



Long distance carrier LONG DISTANCE CARRIER (15G)
As the Charger, grab a Survivor and carry them over 80 feet.
  • As in a telephone company.
  • Falls count toward the distance, charging someone off the balconies in Dead Center will earn you this.
    • Another good spot to get this achievement is on the Rooftop Finale of No Mercy. If you charge off the roof, taking a survivor with you, you will usually unlock the achievement before you hit the ground and die.
    • The Sugar Mill building on Hard Rain works too, when they must turn the elevator on, and it does more then 80 feet (as long as you don't hit pipes or the building).



Wedding-Crasher WEDDING CRASHER (30G)
As the Charger, grab a Survivor and crash them through 8 chairs at the wedding.
  • The chairs must be standing and untouched to count towards the achievement.
  • You must charge from a sufficient distance lest the chairs stop your charge.
  • The name 'Wedding Crasher' refers to a person who shows up at a wedding uninvited for various reasons ranging from free food to flirting with the bridesmaids.
  • The reason that this achievement is so difficult is because human players are aware you will try to charge them at the wedding to get this achievement, therefore they will take extra caution to you and most likely avoid you and the chairs, so it is probably best to sneak up behind a bot lingering around the chairs or wait for the Versus Co-Op Mutation to be released, because Versus Co-Op is where up to four players will be controlling the Special Infected instead of the Survivors, and the Survivor bots most likely will be preoccupied with the Wedding Witch. Use the Wedding Witch as a distraction, spawn behind them and charge one of them into eight chairs.


Scavenge ModeEdit

Hunting party HUNTING PARTY (15G)
Win a game of Scavenge.



Gas guzzler GAS GUZZLER (20G)
Collect 100 gas cans in Scavenge.
  • An easy way to earn this is the communicate with your team and ask them if you can pour the gas in the generator/car.
  • This is obviously a cumulative achievement, since you can only get 16 gas cans in a single round of Scavenge, you can only obtain a total of 90 gas can in a match of scavenge and only if you are playing 5 rounds.
  • Coach is holding a gas can in the picture, although it looks like Louis.
  • Gas-guzzler commonly refers to a vehicle that consumes fuel inefficiently.



Cache and carry CACHE AND CARRY (20G)
Collect 15 gas cans in a single Scavenge round.
  • You do not have to collect them all; if your team scores 15 cans, everyone on the team earns the achievement.
  • The name is a reference to the "Cash and Carry" policy employed by the United States during the WWII era.



Scavenge hunt SCAVENGE HUNT (15G)
Stop the enemy team from collecting any gas cans during a Scavenge round.
  • Best done on a team with 2 or 3 bots as bots won't pick up or even pour the gas cans.
  • Having a good Spitter helps a lot, since spitting on gas cans that have been picked up (with a yellow outline) destroys them, and Survivors can't pour fuel if the ground is covered in acid. As a Spitter, hide near the generator (preferably above) and spit down whenever a Survivor with a gas can gets close to the generator. Ideally, a teammate (Hunter, Jockey, Charger, or Smoker) should also strike at that moment to make the Survivor drop his/her gas can into the acid.
  • This is a reference to the game of searching for items on a list called a 'Scavenger Hunt.'



Fuel crisis FUEL CRISIS (15G)
Make a Survivor drop a gas can during overtime.
  • Simply attack a survivor holding a gas can in overtime.
  • This may be a reference to the high gas prices in the economy.



Gas shortage GAS SHORTAGE (20G)
Cause 25 gas can drops as a Special Infected.
  • Only Hunters, Smokers, Jockeys, and Chargers can cause gas can drops directly (by pinning a Survivor). The Spitter and Boomer have to incapacitate to cause a drop. Tank punches will also cause a gas can drop in the Dead Center finale, but Tanks are not available in Scavenge.
  • This achievement is cumulative and does not need to be done in one game (although technically it could be).



Port-of-Scavenge PORT OF SCAVENGE (30G)
Play 5 full games of Scavenge on The Port.


Survival ModeEdit

Beat the rush BEAT THE RUSH (15G)
In a Survival round, get a medal only using melee weapons.
  • This is easy to achieve - both with human and bot players. Just pick your favourite melee weapon and use no other weapon (not even a pistol if you are downed). You can still use pipe bombs, bile bombs and molotovs. Holding out for 4 minutes is enough to earn this achievement, and your teammates can still use guns.
  • Keep in mind that you have to earn a NEW medal. That means if you lasted for 4 minutes on one map and attempt to get this achievement on the same map, you must earn a silver medal using only melee weapons to obtain this achievement.
  • Unfortunately, this achievement can be permanently locked for some users, as if you earn all of the medals without getting it, as there are no other medals to earn. Though through the use of custom maps that enable Survival mode, it would still be possible to still get this achievement.


MutationsEdit

Mutant-Overloard MUTANT OVERLORD (30G)
Play 6 Mutations.
  • Before July 24, 2012, this achievement would have taken a minimum of four weeks to unlock if you start on a Thursday because you have to play five different Mutations, an old mutation would return for an encore week every four weeks, and then the permanently added Realism Versus could also be played.
  • You do NOT have to actually play through the rounds, all you have to do is join and start the round, to make progress.
  • The achievement can also be earned by using the developer console. By typing map <map file name> mutation# you can start a map with any mutation you want and it will count as achievement progress. You have to replace # with a number for a specific mutation. A list of all mutations you can play can be found here.

  • Getting this achievement awards you with a Gnome Chompski prop for your Xbox Live avatar.
  • Should unlock along with Mutant Overlord.
  • This avatar award used to take a minimum of 4 weeks to unlock, but as of 7/24/12, the Mutations can be cycled through manually and played in quick succession. Since you do not actually have to play the chapter for the Mutation to count, this can now be earned in about 10 minutes. However, game doesn't register Community Mutations on the counter (it counts only one of them), so you may need to load up more than 6 for it to finally unlock.


Left 4 Dead and Left 4 Dead 2Edit

The SacrificeEdit

Supreme sacrifice SUPREME SACRIFICE (50G)
Complete "The Sacrifice".
  • In Left 4 Dead only the person who sacrificed themselves gets the achievement. In Left 4 Dead 2 all players get the achievement.



Killbill KILL BILL (50G)
Have Bill sacrifice himself for the team.
  • This Achievement shares its name with a movie.
  • This is the only Achievement which requires a specific Survivor.
  • This Achievement was probably made to encourage Players to copy Valve and sacrifice Bill. Alternatively, it could also have been made to help it fit with the Storyline in The Passing.
  • In Left 4 Dead the achievement is only obtained by the player who plays as Bill and successfully sacrifices themself. In Left 4 Dead 2 the achievement will be obtained by everyone on the team if the sacrifice is made by Bill.



Chaos generator CHAOS GENERATOR (50G)
Have all three generators running at once in The Sacrifice finale.
  • To accomplish this, get two other players, and then situate everyone near a generator and start them at the same time. If done quickly enough, the achievement will unlock.
  • Every time a generator is started, a Tank will spawn, so be prepared to fight with three Tanks if you want this achievement (Unless you quit the game right after earning the achievement).
  • This achievement will not unlock simply if all three have been started and are running at the same time - all three need to be started simultaneously.
  • This achievement is broken or glitched on the Xbox 360 and will only unlock if playing a game on a local server or via system link (see Crash Course notes section for directions on forcing a game into a local server).



Barrel rolled BARREL ROLLED (50G)
Kill a Special Infected with an exploding barrel.
  • The name most likely comes from a phrase spoken by Peppy Hare from the Nintendo 64 game, Star Fox 64, where he tells the player to "do a barrel roll", a phrase that has become a popular meme on the Internet.
  • The achievement is recorded in favour of flame damage and not by the explosion itself.
  • This achievement is easier to obtain in Left 4 Dead 2 instead of Left 4 Dead, since Chargers can be easily lured into charging into the barrels, and a single explosion should be able to kill it without the bots interfering. It can be similarly done with Hunters, however it is more risky and if you get pounced the hunter will likely be killed by your teammates or bots.
  • Flu Season mutation possibly gives you most opportunities to earn this achievement, since Boomers and Spitters spawn all the time and it's only the matter of luring them next to a barrel.



Sacrifizzle SACRIFIZZLE (50G)
As a Special Infected, incap someone who is trying to sacrifice themselves.
  • In Left 4 Dead 2 you will not take control of a Tank; instead, you will still have to choose your own spawn point in ghost mode. This can make things both easier and harder: you don't have to move all the way to the generator, but you still have to spawn, and you need an Infected that can incap a Survivor.
  • The Survivor doesn't have to be starting the generator - he or she only needs to jump off the bridge.
  • Be aware of AI controlled Tanks, as sometimes they can accidentally kill you when you're trying to grab a Survivor (or even after you grabbed him/her).
  • In Left 4 Dead you'll always take control of a newly spawned Tank. Use this for your advantage. Be quick, however: if the Survivors reacts fast, you might not even be able to get to them.
  • Note, that you only have to deal the incapacitating hit.
  • This achievement was previously glitched for the Xbox 360 version of Left 4 Dead, making it unobtainable. However, this achievement was later patched in an update to the Xbox version and became obtainable, although it remains partially glitched as it will not unlock on dedicated servers; it will only unlock on local servers or system link games (see Crash Course notes section for directions on forcing a versus game into a local server).
