The third part of a post-apocalyptic action-shooter set in the midst of an alien invasion. Most humans and animals have already been wiped off the planet, the ecosystem has been altered to suit the needs of the aliens, and the air has been made unbreathable for most earth creatures, including humans. You start off as one of the many humans taken prisoner by the aliens. They will brainwash you and turn you into a mindless soldier to fight against your own kind. Your mission: Escape and survive!
