The first level in AliensDM is the APC drop site. The second level is a circular/hexagonal map, designed to represent the Alien ship; this featured a teleportation bug that made it impossible to finish the game. Most of the regular STAR textures are used, with few modifications. The Alien eggs are exploding barrels. The chainsaw has been replaced with a welder, used by Hicks and Ripley to try to rescue Newt (Carrie Henn), and the BFG9000 is the flamethrower.
