And make sure that there is nothing like a gamepad attached to your computer. With this description someone should be able to think of something.Īnyway you can try deleting your Killing Floor system folder (C:\program files\steam\steamapps\common\killing floor\system) and then verifying the integrity of the game cache. So try messing around, and perhaps ask around on some tech forums as well. Perhaps you pressed weird key combination that changed a keyboard setting. So try looking into keyboard drivers and special keyboard settings. You can bind the movement keys perfectly to a gamepad or a mouse, but for some reason it won't work on any keyboard any more. Its as if for some reason pressing the forward button makes you move forward and backward at the same time. looks like you're quickly moving forwards and then backwards, and is most likely an actual keyboard setting or whatever on your computer. The last 2 just formatted their computer to fix it with the Red Orchestra game, so atm I do not know of any real fix.
