Version differences[edit]

Classic 2000 edition includes the added content from the Gold Edition, as well as modifications to run the game on modern systems without requiring tweaking.
Only the and Steam versions of Classic 2000 include multiplayer.
Classic 2000 edition features a bug where the alien's colored vision highlights around humans changes constantly, so that it's unreliable for telling if a human is unarmed or has a gun.

Essential improvements[edit]


Patches are available for both the Windows and Macintosh versions. Digital distribution versions are already patched.

Peixoto's patch[edit]

Peixoto's patch allows high resolution without shrinking the HUD\menus and Super sampling anti aliasing


  • Fixed AvP Classic Soundtrack - restore's the Classic version's soundtrack so that the right music is played on the right level. Without it each of the level tracks is played 1 level prior to the level it should be played on.
  • Aliens versus Predator Classic Redux - a completed project that updates and expands the original Aliens vs. Predator Classic 2000. It replaces almost every model, texture, and sound in the game with higher quality ones. Every single-player and standard multiplayer map has these improvements, and some single-player levels have significant additions.
  • AvP Direct3D9 Renderer - updated renderer for improved compatibility (almost pointless with classic 2000 version, except for resolution independent menu rendering)


An unofficial Linux and another OS X port were created and their source code is available here. It contains compiling instructions and required dependencies for compiling.
