Template:Infobox Alien vs Predator is a first-person shooter developed by Rebellion Software and published by Atari Corporation for the Atari Jaguar in 1994. Based on the Alien vs. Predator franchise, the game allowed the player to choose one of three characters: the Alien, the Predator, or Colonial Marine Pvt. Lance Lewis.
The game's engine is much like Wolfenstein 3D: a flat plane, no stairs or open elevators, two-dimensional sprites, and all walls turn at 90 degrees (but sometimes with transparency). Each character was well balanced and provided a different gameplay style (the levels were the same, but the strategies different). Playing as the Marine, you had computer terminals to learn the ill fates of the other marines (similar to the PDAs in System Shock). Alien vs Predator is a precursor to the popular PC game series released in 1999, which used 3D polygon graphics.
The Space Marine, Pvt. Lance Lewis, was named after the game's level designer/game tester.
There are a number of screenshots of the game on the web, taken from magazines, that are from a version of the game slightly different from the final release game. The most noticeable differences between these two versions are between the enemy sprites.
A version with similar 3D gameplay was also planned for the Atari Lynx but it was cancelled when Atari dropped support of the Lynx. After finishing Alien vs Predator, Rebellion Software started work on another first-person RPG called Legions of the Undead. Using an improved engine, this Hellraiser-like game never saw the light of day due to the commercial failure of the Jaguar. Rebellion Software also worked on the first Aliens vs. Predator for the PC.
