Aliens Online

Maps ranged from a loose reproduction of the colony from Aliens, to a derelict spacecraft with an Alien hive in the lower levels. Every map had cramped air ducts or sewer pipes that the Aliens could speedily, and usually securely, make use of - with hatches that allowed the player to drop onto unsuspecting marines and rend them with claw and tail attacks.

Marines carried a selection of long-range firepower based on the weapons in the film. A lone marine only had access to a pulse rifle, pistol, shotgun, and motion tracker (deployed like a weapon, and not part of the HUD). Up to four marines could also band together in a fireteam, unlocking heavy weapons like the flamethrower and the auto-tracking SmartGun. Members of a fireteam could also open minature "helmet cam" windows for each of their teammates, and see a feed of what that player was seeing.
