If this was real, it propally be the Hardest game mode. A mix between Ultra Realism and Last Man on Earth.
Rules: You only get one chance to get one chance to get away from being incaptitated per Chapter. No team mates to help you. There are no outlines around anything. No HUD to check your ammo and health. But if you complete a Campaign, You are Legend.
Tagline: You are Legend.
