Essential improvements

Patches

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

Peixoto's patch

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

Modifications

• 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.

Ports

• AvP Direct3D9 Renderer - fan made source port used as a base for the Classic 2000 re-release. Compatible with modern systems, but has several bugs (broken Xenoborg rendering, star skybox not being rendered, huge HUD on widescreen resolutions, main menu music not looping, only one CD track being played per level).
• 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.

Input

Keyboard and mouse	State	Notes
Remapping
Mouse acceleration		There is negative mouse acceleration. Also, the more FPS the game runs on, the higher sensitivity is.
Mouse sensitivity		There is a slider for each axis. However, when these sliders are on equal notches, horizontal sensitivity is higher than vertical sensitivity. 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.
Mouse input in menus
Mouse Y-axis inversion

Issues fixed

Game crashes at the end of the mission

In some missions game crashes, when player presses any key at the results screen.

Use a restart function
Play through a level like you normally would. At the end of a level, when the game displays stats press Esc to restart the mission. Press Esc again to go to in-game menu and choose Abort Play to go back to main menu. Choose Single Player and after that choose a campaign, they you've just been playing. Choose a newly unlocked mission from the list and continue your playthrough.

Run AvP_Classic.exe in compatibility mode for Windows 98 / Me and with disabled high DPI scaling.

Aliens versus Predator Classic Redux

A 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.
