Aliens versus Predator 2 is a science fiction first-person shooter video game developed by Monolith Productions and published by Sierra On-Line for Microsoft Windows in 2001, and for Mac OS X in 2003. The game is a sequel to Aliens versus Predator (1999); both games are based on the characters of the Alien and Predator media franchises as well as the Alien vs. Predator crossover series. It is set on the fictional planet LV-1201.
The game is played from a first-person perspective. In the single-player mode, players control one of three characters, each with their own abilities and individual story modes. An online multiplayer mode, which allows players to play as one of four teams in competitive modes, is no longer officially supported and requires a community developed patch to enable multiplayer.
An expansion pack titled Aliens versus Predator 2: Primal Hunt was released in 2002. A "Gold Edition" of Aliens versus Predator 2 followed, combining both the original game and the expansion pack into a single package. There was never an Aliens versus Predator 3 nor any plans for a sequel, but in 2010 Rebellion Developments made a reboot simply titled Aliens vs Predator.
