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 Patches or the use of the third-party software GameRanger to enable online functionality.

Requires the official patch and Single Player Map Update #1.
Includes widescreen and high resolution support, anisotropic filtering in the custom performance menu, a mouse input fix, and framerate issue fixes.
Includes a console with commands for turning off visor color inversion, showing the framerate, toggling patch options, etc.
Incompatible with custom launchers.

Widescreen resolution

Use the Master Server Patch[citation needed]
  1. Install patch and Single Player Map Update #1 from the Patches section.
  2. Install the Master Server Patch.

Custom launchers

Alternative method: Use custom launchers[1]
  1. Install patch and Single Player Map Update #1 from the Patches section.
  2. Download launcher executables for the base game and/or expansion.
  3. Place chosen executable(s) in <path-to-game>.
  4. Run the launcher for the base game or expansion and configure desired settings.


Allows the FOV to be freely configured to a chosen number value.
Needs to be run with administrator privileges in order to launch.
Conflict with the Master Server Patch, preventing the use of the patch's console.
Alternative method: Edit autoexec[2][dubious – discuss]
  1. Install patch and Single Player Map Update #1 from the Patches section.
  2. Open the autoexec.cfg file located in <path-to-game>\Fox\Aliens vs. Predator 2 with a text editor. For Primal Hunt, the file is found in <path-to-game>\Fox\Aliens vs. Predator 2 - Primal Hunt.
  3. Search for the following entries:
  4. "SCREENWIDTH" "#"
    "GameScreenHeight" "#"
    "GameScreenWidth" "#"
  5. Change the resolution numbers that appear after those entries to the desired screen resolution.


It is possible to use resolutions that go beyond the game's resolution settings, but accessing and modifying the display settings in the game launcher will immediately overwrite the value.
FOV will be stretched to fit the aspect ratio.
Does not work for resolution heights greater than 2048 or resolution widths greater than 1536.

Borderless windowed

Master Server Patch: Activate borderless windowed mode[2]
  • Add +windowed 1 and +borderless 1 command line arguments to the advanced command-line in the Options section of the launcher.
Lithfix: Activate borderless windowed mode[citation needed]
  1. Go to <path-to-game> and open autoexec.cfg in a text editor.
  2. Create a new line at the top and type "lf_borderless_window" "1.0".
  3. Save the file.


With the custom launchers, borderless windowed mode can be toggled in the Game settings section of the custom launcher.
Use Borderless Gaming[citation needed]

Issues fixed

The game does not launch or crashes when loading a level

Run avp2.exe in compatibility mode for Windows 98 / Me and as administrator[citation needed]

Windows 8 low frame rate in fullscreen

Use low frame rate fix[2]


May cause black screen freezing on startup for Windows 10.

Uncontrollable mouse movement

Mouse moves in wavelike pattern when attempting y-axis movement.
Decrease mouse polling rate to 125 Hz[2]
Use the Master Server Patch
Install mrNuku and Ayleia's dinput.dll[2]


Fixes a common crash on launch.
Conflicts with DI-wrapper.
Will require reassigning mouse buttons.
Alternative method: Use DI-wrapper[3]


Conflicts with mrNuku and Ayleia's dinput.dll.
Will require reassigning mouse buttons.
Alternative method: Use LithFix for smoother mouselook[citation needed]
  1. Download LithFix and copy it to <path-to-game>.
  2. Remove any custom .rez files and add -rez lithfix to advanced command-line in the launcher.


Custom launchers have basic support for LithFix since version 1.3.0 (base game) or 1.1.0 (Primal Hunt).
Conflicts with Master Server Patch.[2]

Screen turns black in alternate Alien and Predator vision modes

With recent graphics drivers, the game's color inversion does not work, resulting in the Alien vision and the Predator tech visor displaying black screens.[4][5]
Disable inverted vision modes in the Master Server Patch's console[2]
  1. Install the Master Server patch.
  2. When in-game, hit ~ on the keyboard to open the console.
  3. Type invertbypass into the console and hit enter to toggle the inversion off.


Works in both multiplayer and singleplayer.
The toggle will be saved, remaining on or off through restarts as set.
Changes the look of the inverted vision modes significantly.
Doesn't work for "Primal hunt" expansion.
Alternative method: Disable inverted vision modes by installing the vision mode fix[2]
  1. Download the file and unzip it in the custom subfolder in <path-to-game>\Fox\Aliens vs. Predator 2. If the folder does not exist, create it.
  2. In the launch settings, go to Options, then type in the -rez custom/visionfix.rez command line argument.


Can also be installed to <path-to-game> and launched with the -rez visionfix.rez command line argument.
Changes the look of the inverted vision modes significantly.
Only works in singleplayer.
Predator's night vision does not work underwater.
Alternative method: Install dgVoodoo 2[2]
  1. Download the latest version of dgVoodoo 2 and unpack it (verified working on version 2.82.3).
  2. Extract dgVoodooCpl.exe and dgVoodoo.conf, paste them into <path-to-game>.
  3. Extract D3D8.dll, D3D9.dll, D3DImm.dll and DDraw.dll from the MS\x86 folder to <path-to-game>.
  4. Run dgVoodooCpl.exe and configure the settings.


Makes the inverted vision modes display properly, rather than turning off their color inversion.
Can be used to force anti-aliasing and higher resolutions without shrinking the HUD and menus.
Works with all patches except the Windows 8 FPS fix.
Has severe performance issues with the game's dynamic lighting.

Cutscenes play too fast

Cap the frame rate at 60 FPS[2]
Set monitor refresh rate to 60 Hz[6]

MFC Application Client Application Has Stopped Working error

This error seems to also occur more often when running in fullscreen mode; consider using windowed or borderless windowed mode.[citation needed]
Install the Master Server Patch[2]
Check the Windows Event Log for the application error - if it refers to a \system32\HID.DLL then it's likely an error with some input devices.[citation needed]
Install mrNuku and Ayleia's dinput.dll[2]


Built to solve this crash, mouse issues, and any problems with keybindings.
Conflicts with DI-wrapper.
Disable HID devices[7][8]
  1. Open the Windows Device Manager.
  2. Expand Human Interface Devices.
  3. Right-click on each driver starting with "HID Compliant", and left-click on "Disable Device".


Test re-enabling them and re-launching the game one after the other to determine the driver(s) causing the problem.
Uninstalling these drivers tends to result in them being reinstalled and reenabled almost immediately.

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".
