"Alien vs Predator" is a first-person shooter presented with digitized graphics on a rudimentary 3D environment, similar to "Wolfenstein 3D", with two-dimensional digitized sprites. Each of the three playable characters have their own scenario, objectives, weapons, abilities and disadvantages. All of the enemies in the three campaigns do not emit any other sound effects, except when they are attacking the player. Progress, high scores and other settings made by the player are manually kept by pausing the game and saving in any of the three available save slots via the cartridge's internal EEPROM.
