cloaking device to become invisible and several different modes of vision to help in the detection of enemies, including infrared vision and a mode sensitive to electrical systems. Unlike in the previous game, the Predator in Aliens Versus Predator 2 recharges its energy supply using a personal item. As the Colonial Marine, the player uses a number of weapons to combat Aliens and Predators. The Marine wears armor for protection, and uses an image intensifier, flashlight, and flares to improve visibility in dark areas. Multiplayer Aliens Versus Predator 2 has several multiplayer modes which can be played through an internet or local area network connection. In each game the player chooses one of four teams to play as: The Aliens, Predators, Marines, or corporate mercenaries (called "Iron Bears" in the game's storyline).

The Aliens are able to scale walls and ceilings and the Predators can become invisible, while the two human teams have a large array of heavy weapons as well as motion trackers. There are six different multiplayer "modes" played on a number of "maps". "Deathmatch" mode is a free-for-all match in which the player's goal is to accumulate the highest number of kills. "Team Deathmatch" has the same goal except that the player is teamed with other players of the same species (or faction, in the case of the Colonial Marines and the Corporate Mercenaries). In "Hunt" there are two teams, one designated as the "hunter" and the other as the "prey"; the hunters accumulate points by killing the prey, while the prey can themselves become hunters by killing members of the hunter team. "Survivor" mode designates all players as "defenders" at the start; if a player is killed they become a "mutant" and can then earn points by killing defenders. Defenders gain points by staying alive without becoming mutants. "Overrun" is a timed match between two teams that is similar to "Survivor" except that each player has a finite number of lives; at the end of the round points are awarded based on the number of surviving members on each team. "Evacuation" is another two-team match with a finite number of lives, in which one team is designated as the "attackers" and the other as "defenders". The attacking team wins by killing all of the defenders, while the defending team wins by locating the map's evacuation point and having
