Rage

Rage is a first-person shooter set in the not-too-distant future after an asteroid impacts Earth, leaving a ravaged world behind. You emerge into this vast wasteland to discover humanity working to rebuild itself against such forces as raider gangs, mutants, and the Authority – an oppressive government regime that has a special interest in you in particular.

On August 23, 2029, the asteroid 99942 Apophis collides with Earth, destroying human civilization and turning the world into a wasteland. Survivors come together to form settlements around oases and other practical or habitable locations, while the wastes are plagued by various bandits clans, and mutants, who attack all normal humans in a voracious horde.
