Aliens: Colonial Marines is a squad-based first-person shooter in which the player controls four Colonial Marines, each with a different personality and primary weapon. Each player character can carry additional weapons including a flamethrower, pulse rifle, smartgun, pistol, RPG, and many types of grenades. The player controls one marine at a time, issues orders to the others using context-sensitive commands, and may switch between characters at any time.
Good game for fans made even better with a few mods. not a great aliens game but it was very entertaining and me and my friends enjoyed the various multiplayer modes during several LAN nights.
