  2. Right-click Killing Floor.exe and choose Properties.
  3. Go to the Compatibility tab.

  2. Right click on game and select Properties
  3. Select Set Launch Options
  4. Enter -windowed into the dialogue.
  5. Click OK
  6. Start the game and it should be fixed

Notes

Once the game starts, you can then maximize the window to play full screen
This issue can also be caused by playing the game in a non-native resolution, meaning the pixel size your screen is set at.

No Online Games/0 Servers from Master list[edit]

Delete your ClientRegistry.blob file[citation needed]
  1. Exit Steam.
  2. Go to C:\Program Files (x86)\Steam
  3. Delete ClientRegistry.blob
  4. Open Steam again and relaunch the game.

Re-enable gore[edit]

Depending on your version of the game, Killing Floor can have gore disabled. This fix re-enables gore.
Manually re-enable gore[citation needed]
  1. Start the game at least once, so it can create all configuration files.
  2. Go to <path-to-game>
  3. Open System\KillingFloor.ini
  4. Search for the line [Engine.Engine]
  5. Add bdevgoreoverride=True on a new line at the bottom of the [Engine.Engine] configuration block.
  6. Save the file, restart Steam and enjoy your uncut game.

Main menu unreadable in windowed mode[edit]

The main menu may be unreadable when starting the game in windowed mode. Switch to fullscreen mode.[3]

Sound stuttering in ArchLinux[edit]

Replace openal.so file[citation needed]
  1. Back up the openal.so located in <path-to-game>/System and install lib32-openal. If you are on 32-bit system, install openal
  2. Symlink the installed library with one of these commands:
  • ln -s /usr/lib32/libopenal.so.1 <path-to-game>/System/openal.so
  • ln -s /usr/lib/libopenal.so.1 <path-to-game>/System/openal.so
