Aliens versus Predator (1999)

Aliens versus Predator, nicknamed AVP1, is a horror-themed first-person shooter game by Rebellion Developments, and the second Alien vs. Predator game they made, after the Atari Jaguar game Alien vs. Predator, released in 1994. It was released in 1999 for Microsoft Windows and macOS.

A stand-alone expansion pack was released in 2000, called Aliens versus Predator: Gold Edition. That edition was then re-released in 2010 on Steam and GOG.com as Aliens versus Predator: Classic 2000.

Gameplay
Like the Jaguar game and the rest of the AVP FPS games, the game allows you to play as either an Alien, a Colonial Marine, or a Predator, each with their own abilities and weapons.

Why It Rocks

 * 1) Succeeds in building a terrifying and downright scary atmosphere.
 * 2) A suspenseful and minimalist soundtrack which is appropriate for the game.
 * 3) Variable gameplay, depending on what you’re playing as. But regardless, the game remains very challenging and fast-paced; you are encouraged to keep moving because enemies will not stop respawning and they will chase after you.
 * 4) Each species has multiple vision modes which can aid you in making your way through barely-lit areas or tracking down and detecting enemies.
 * 5) Gruesome combat; all three species are susceptible to mutilation. As an Alien you are encouraged to destroy your enemies’ bodies to regain your health.
 * 6) Tolerable graphics by 1999 standards.
 * 7) Various NPC types for each species, ranging from marines, civilians, and Predators that carry various weapons to Alien castes such as facehuggers and Predator-Alien hybrids. They all have their strengths and weaknesses.
 * 8) Aside from new weapons, the Gold Edition adds a Skirmish mode which basically serves as a "survival mode" where you play as either a Marine or a Predator fighting against hordes after hordes of Aliens until certain conditions are met. It also makes the game slightly more forgiving by adding in-game save options.
 * 9) Has plenty of interesting and cool cheat options, accessible either by meeting certain conditions or by playing the game via debug mode.

Bad Qualities

 * 1) Rather short; the three campaigns, including the bonus levels, can be beaten in less than four hours.
 * 2) The game's original retail versions suffer from compatibility issues in newer operating systems that thankfully can be rectified using fan-made patches.
 * 3) Limited modding capabilities, despite the fact that the game's source code has already been released; a lot of the mods alter the game's graphics and sound, but there is hardly ever a mod that actually alters the gameplay in any way safe for AvP Classic Redux and Cancer Black.
