Version differences

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 GOG.com and Steam versions of Classic 2000 include multiplayer.

Essential improvements

Patches

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

Modifications

• 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)

Ports

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.

Downward movement, and movement to the right both have a small dead-zone, and sensitivity for these directions is slightly lower than for the opposite directions.
