Alien Trilogy takes the first three movies of Fox sci-fi diaspora and fashions an effective Doom clone out of them. Marines have landed on a colony planet which has lost contact with earth. Very quickly they find the place infested with xenomorphs, ranging from face-huggers to fully grown aliens. Perhaps in a bid to add some variety to the foes, many levels feature genetically modified 'enemy' marines. The levels are depicted in fast, moody 3D - the game becomes extremely dark in places. The game engine is not as sophisticated as comparable titles like Exhumed, for example, you can't look up or down, or jump. This also limits the range of gameplay actions. Alien Trilogy is mostly a race from level start to exit, unlocking blast doors in between. The game successfully replicated the weapons and settings of the movie series, down to the pulsing motion tracker made memorable by Aliens. Viewed now, the limitations of Alien Trilogy are apparent. 3D games, after all, have moved on a hell of a lot. It still functions very successfully as a movie to game conversion, mainly because the atmosphere works so well. The player will also get a few shocks from this blaster as they progress, and the visual effects still stand up. However this no longer looks like cutting edge stuff. 8 OUT OF 10 reviewed by Stephen Fulljames
