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.

Essential improvements[edit]


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


  • 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)
