GameSpy online services have been shut down (see Network for solutions).

Aliens versus Predator 2 is a singleplayer and multiplayer horror sci-fi FPS in the Aliens versus Predator series set in space and developed by Monolith Productions.

The game was released to Windows on October 23, 2001. The following year in August 2002 an expansion pack developed by Third Law Interactive titled Primal Hunt was released. In May 2003 the Gold Edition was released which bundled the base game with the expansion pack. Two months later on July 23, 2003 an OS X port developed by The Omni Group was released.

As the multiplayer service GameSpy has terminated its services, the game requires either a community-created Master Server Patch or the use of the third-party software GameRanger to enable online functionality.

Uncontrollable mouse movement

Master Server Fixes for the Base Game and the Primal Hunt expansion pack:
  1. Install the Master Server Patches from the AvP2 Master Server Patches section.


You still may be required to use something like dgVoodoo to fix black screen issues.
Alternate method: For the Primal Hunt expansion pack, use LithFix for raw input:
  1. Download LithFix and copy it to installation folder.
  2. Remove any custom rez files and add -rez lithfix to advanced command line in the launcher.


Custom Launcher has basic support for LithFix since version 1.3.0 (AVP2) or 1.1.0 (AVP2PH).
Alternate method: Decrease mouse polling rate to 125 Hz.[citation needed]
Alternate method: Use DI-wrapper.[3]
  1. Download DI-Wrapper and copy it to installation folder.

Black screen when using alternative visions with the Alien and Predator

In recent graphics drivers, some pc's don't display the proper alternative vision modes, instead showing a black screen.[4][5]
Install Aliens vs. Predator 2 Vision mode fix
  1. Download the file and unzip it in the custom folder located in <path-to-game>\Fox\Aliens vs. Predator 2. If the folder doesn't exist create it.
  2. In the launch settings go to options, then type in the command-line parameters -rez custom/visionfix.rez

Alterntatively you can add the same command as a launch option, by typing it at the end of the target within a desktop shorcut.

Cutscenes play too fast

Cap the frame rate at 60 FPS[citation needed]
Set monitor on 60HZ[6]

The game won't launch

If nothing happens when you click the .exe you might have to try running the game in Windows 98 compatibility-mode. To do this right-click avp2.exe, click options and go to the compatibility-tab. Check the compatibility-box and choose Windows 98.[citation needed]

Running the game as an administrator has also prove useful in launching the game for some people.

If it says something about "MFC Application Client" - Check the Windows Event Log for the application error - if it refers to a \system32\HID.DLL then you're probably using a gaming-keyboard or similar, try disabling the HIDs related to your gaming-peripherals or you can also set the compatibility. This error seems to also occur more often when running in Fullscreen mode; consider using Windowed mode (possibly in conjunction with the Borderless Gaming utility).

MSI Afterburner overlay makes the game crash

Change the settings in RivaTuner[citation needed]
  1. After launching MSI Afterburner, open the Riva Tuner Statistics Server from the system tray.
  2. Add lithtech.exe from <path-to-game> to the settings.
  3. Set Stealth mode to "ON".

MFC Application Client crashing when load levels

Find avp2.exe and lithtech.exe (located inside the game's root folder, where the .exe file is) right click on lithtech.exe properties compatibility tab check run this program in compatibility and choose Win98/ME and check run as admin and click apply. Right click on avp2.exe properties, compatibility tab check run as admin and click apply
