Alien Trilogy is a first-person shooter developed by Probe Entertainment and released in 1996 for PlayStation, Sega Saturn, PC, DOS, Sega 32X, and Sega CD. Drawing directly from the Alien film series, the game features a roster of enemies drawn from the franchise, including facehuggers, chestbursters, dog aliens, adult aliens, and Queen aliens. Players progress through 30 levels across a single-player campaign, confronting three Queen alien boss encounters along the way. A selection of weapons is available to handle the escalating threats throughout the game. The structure and enemy design reflect the tone and creature hierarchy established across the film series, making it a reasonably faithful adaptation of the source material in terms of its core cast of antagonists.

Storyline

In the role of Lieutenant Ellen Ripley, the player experiences a story loosely derived from the first three films of the Alien franchise. Aside from occasional CGI cut scenes, the plot is told through text-based mission briefings that guide the player through an expanded, action-oriented story, drawing upon the settings and characters of the then-trilogy rather than through the specific plots of the films themselves. The game begins in essentially the same manner as Aliens, as Ripley—here a marine herself—travels to LV426 to restore contact with the colony there. The other marines are wiped out, so Ripley must then travel through the infested colony and prison facility, and finally the crashed alien ship itself, to destroy the aliens and escape.
