An apocalyptic action shooter set in the midst of an alien invasion. Most humans and animals have already been wiped off the planet, the eco system has been altered to suit the needs of the aliens, and the air has been made unbreathable for most earth creatures, including humans. Few humans are still alive. They are scattered, hiding in underground shelters and their fight for survival is a hopeless one. Desperate needs call for desperate measures, which could bring even more destruction.
Your mission: Survival.
