Startup issues

Game crashes at main menu

Replace openal32.dll[3][5]
  1. Go to <path-to-game>\bin and rename openal32.dll to openal32.dll.bak. This ensures original DLL is preserved should you need to revert this fix.
  2. Download the latest version of OpenAL Soft (PCGamingWiki mirror)
  3. Extract the contents of the zip file you downloaded to the folder of your choosing.
  4. Open folder you extracted and go to openal-soft-<version number>-bin\bin\Win32
  5. Copy the DLL, named soft_oal.dll in the folder and paste it into <path-to-game>\bin.
  6. Rename the DLL you just copied to openal32.dll.


This fix has only been tested with discrete sound card users (i.e. Creative X-Fi series of sound cards).

Game crashes on startup

Users of Nvidia GeForce GTX 260, GTX 275, and GTX 280 cards have reported their graphics card drivers crashing when attempting to start the game.
The developers recommend any Nvidia users experiencing problems to first read this Instructables article for detailed information on fixing the problem.
Modify registry settings[3]
  1. Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers
  2. Change the decimal value of TdrDelay to 10 or higher.
  3. If the preceding step does nothing, change TdrLevel to 0.


If the keys listed above do not exist, you will have to create them, ensuring they are named exactly as listed in the fix as well as creating them as type REG_DWORD.

Netcode issues

Desynchronization (de-sync)

Work is ongoing to improve netcode and reduce or eliminate de-syncs.[6]

Gameplay issues

Game crashes on mulitplayer maps

Affects singleplayer "Survival" mode and multiplayer.[7]
The developers are actively working on a fix.[8]

Singleplayer missions exhibit choppiness/jerkiness

This is a known, difficult-to-diagnose issue.[9]

Invisible solar rays

Solar radiation rays, which appear in the final moments of a multiplayer game, are invisible, yet still deal Solar damage.[10]
This is a regression of a previously-fixed issue.[11]

Low FPS in Multiplayer

When playing on the Central District map on Veteran difficulty and on Fast mode with primary and secondary objectives enabled, all players experience low FPS and absolutely no synchronization after Wave 9.[12]
Has the side-effect of preventing players from damaging enemies.
Developers are aware of the issue and are working on a permanent fix.
Disable item descriptions[13]
