[9] The single-player campaign presents the player with a conventional series of levels to progress through that are designed around the abilities of each character.

The marine wears armor for protection and uses an image intensifier and flares to improve visibility in dark areas.

The player can also use a form of echolocation in dark areas and can detect pheromones to discern human or Predator enemies.

When the Ferarco's self-destruct system is activated, the player must reach the escape shuttle, which takes them to Gateway Station from Aliens (1986).

Next the player explores the atmosphere processing station and shuts down its cooling valves in order to cause an explosion which will wipe out the Aliens.

The player defeats the hybrid, triggers the facility's self-destruct mechanism, and escapes in the Predator ship.

[18] Following the source code release, the game was unofficially ported to Linux and hosted at icculus.org in 2001,[19] Xbox in 2009 and for PlayStation Vita in 2020.

[21] This release can be purchased either through Valve's Steam digital distribution service,[22][23][24] through Green Man Gaming, or through GOG.com[25] where it started as a free giveaway.

[26] A patch released on 19 January 2010 added proper widescreen support, optional unlimited saves, a locked frame rate, mouse improvements, and other updates to the game.

[29] IGN praised the game for allowing the player to play three different characters, each with a unique game-play element, and for being "fun and terrifying at the same time".

[7] Edge gave it a score of eight out of ten, saying, "Equally, while AvP lacks the glossiness of its peers (Unreal, Half-Life, etc.)

[...] the fabulously horrific, tense, and uniquely skewed action will doubtless be enough to make it a film favourite with those PC gamers who possess an insatiable appetite for firstperson [sic] thrills.

It's a shame that the engine didn't have the graphical clout of, say, an Unreal, or some more inventive level design, but it's fine for creating an atmosphere, a commodity it oozes at every step, making it one of the most memorable gaming experiences you're likely to survive.

[47] Aliens Versus Predator was nominated for PC PowerPlay's "Best Sound FX", "Best Enemy", and "Best Firstperson [sic] Shooter (Single Player)" awards, all of which went to Half-Life.

[48] Aliens Versus Predator was also a runner-up in PC Format's "Best Shoot 'em Up Game" category, which was ultimately won by Quake III Arena.
