Alien Trilogy

The game consists of 30 levels and 3 bosses. It implement many elements from Alien film series, including enemies such as facehuggers, chestbursters, and weapons, such as the pulse rifle. The console versions only have a single player campaign whereas the DOS version also features deathmatch network multiplayer.

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 franchise 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.

In early 1994, Acclaim announced that Alien Trilogy would be the first game to use the 3D motion capture technology created by their engineering team Advanced Technologies Group. The aliens' movements were created using this technology.

Many of the game's sound effects, such as the cocooned colonists whispering "Kill me" and the alien screeches, were sampled from the films.

Alien Trilogy received generally positive reviews from critics. On aggregating review website GameRankings, the PlayStation version held a 78% based on 5 reviews. The four reviewers of Electronic Gaming Monthly gave the PlayStation version their "Game of the Month" award, concurring it to be the best video game based on the Alien franchise yet, chiefly due to the graphics and sound effects authentically recreating the style of the films. Two of the reviewers also commented that the use of mission objectives gives the game more depth than the average first person shooter.

GamePro also commented positively on the sound effects but was not impressed by the graphics, remarking that though they are faithful to the films, they are overly monochrome and suffer from extreme pixelation. The reviewer also complained of targeting problems but gave the game a strong recommendation due to "the fun of cruising the halls, wiping out aliens, and torching and detonating the area." A reviewer for Maximum likewise was pleased with the sound effects but felt the graphics to be authentic to the films yet unimpressive, remarking that the animation on the aliens is a severe disappointment after Acclaim's considerable boasting about their new motion capture technology. He also criticized the slow pace and weak weapons, but praised the game's limited field of vision for creating a claustrophobic, suspenseful atmosphere and concluded that Alien Trilogy "is far more impressive than the mediocre offerings PlayStation owners have had to put up with over the last few months, with a depth of gameplay and audio-visual quality which is sure to impress just about everyone who buys it."
