In the year 2135, a man known as "Ark Survivor" awakes from cryogenic preservation; he finds that 106 years ago a meteor struck the earth, killing innumerable people and mutating many others into violent abominations.
A meteor called Apophis strikes the earth, wiping out most of the population. The remaining survivors form camps and small towns, along with various bandit camps. When the meteor hit, it had a lethal amount of Feltrite on it, that fiddled with the D.N.A of some people, turning them into monsters.—mattga1
Anticipating the meteor strike, members of the population were buried in chambers and kept in stasis using technology that will aid you in your game play. You enter the game newly emerged from one such chamber to find proto-societies in existence and an evil organization intending to rule over everything and seeing you as a direct threat.
