There's a pistol, shotgun, pulse rifle, flamethrower and smartgun to fight the enemies with. Weapons are the standard set seen in Aliens, with the addition of seismic charges (which were only mentioned in the film). Though it is similar to Doom, limited use of the Y-axis can be used to look up and down, whereas in Doom there was no Y-axis aiming. If the player gets less than 50% in 'Mission' and/or 'Aliens' meters, the mission must be repeated. There are objectives that must be addressed and Aliens must be eliminated. Gameplay wise, Alien Trilogy is best described as a straightforward shooter. The first is on the Colony, anologous to Aliens, the second is on the Prison, anologous to Alien 3 (which isn't canonical since in the film, the prison had no weapons) and the third in on the Derelict spaceship, anologous to Alien though most of the level scenery is invented by the creators since so little of it is seen in the film. The storyline is advanced solely through the use of detailed text-based mission briefings at the start of each level and there are short cut scenes at the end of each game that provide a small amount of closure to the events of the preceding missions. The player undertakes the role of Ellen Ripley, the main character of the movies (portrayed by Sigourney Weaver) and apart from Bishop, there are no other major characters in the game.

The game only loosely follows the storyline of the Alien movies. It was released for PlayStation and Sega Saturn in 1996, and later ported to MS-DOS in 1997. Alien Trilogy is a science fiction first person shooter loosely based on the first three Alien movies.
