Like this month's exceptional Left 4 Dead, Colonial Marines is a four-player co-op game centred around survival: you're constantly under attack and the environments you move through are frequently hiding your enemy. However, whereas Left 4 Dead pitches you into the middle of a nameless American city awash in zombies, Colonial Marines goes for fan-pleasing recreations of the movie quadrilogy's best locations: LV-426, the planet where the Nostromo first discovers the derelict alien ship in the original film; the Sulaco, where Ripley joins up with the marines in Aliens; and Fiorina 'Fury' 161, the prison facility from Alien 3.During the game you will be able to issue commands to your squad-mates, or switch to each of them at will. Each member has specialized skills and guns that are unique to each character.
