Aliens vs. Predator: Requiem is a video game exclusively for the PlayStation Portable, developed by Rebellion Developments and published by Sierra Entertainment in November 2007 in North America and Europe, and December 2007 in Australia. It is an entry in the Alien vs. Predator franchise, an amalgamation of the Alien and Predator franchises. Aliens vs. Predator: Requiem is a tie-in to the film of the same title, which was released shortly after the game.
The game's plot is loosely based on the film's, and players take the role of the film's primary Predator. After the events of the first film in the franchise, the Predator has been charged by his society to hunt down and destroy any trace of Alien activity taking place in a small American town, to avoid detection by humanity. The game takes place in several areas in and around Gunnison, Colorado.
