An epic bug hunt featuring a unique blend of co-op play and squad-level tactics. With your friends, form a squad of four distinct IAF Marine classes. Plan your attack using an unlockable arsenal of weapons with countless loadout configurations against a wide variety of aliens. Blaze your way through an overrun, off-world colony, eradicating the alien infestation in environments ranging from the icy planet's surface, to a subterranean lava-flooded mining facility.
Probably one of the best alien oriented games I've played. I'd suggest getting friends to play this game with you though considering the lack of people on servers and the AI on the bots are horrendous. All in all this game is very entertaining and very difficult.
