got it working under mac os x doing a few tweaks, changed the graphics to direct3d which stopped the game crashing when the final boss spawned
also did the following reg edit to stop it from limiting the character movement
- Go to the Programs menu in Crossover, then select Run Command.
- Type 'regedit' (minus the quotes) into the command box, and make sure that Use Bottle has the appropriate bottle selected. Press enter or run.
- Navigate to HKEY_CURRENT_USER/Software/Wine/AppDefaults/
- With AppDefaults selected, click Edit->New Key. Type 'KillingFloor.exe' (again, without the quotes) and press enter. The key will appear under AppDefaults.
- Now, with Killingfloor.exe selected in the tree, once again select Edit->New Key. Call the key DirectInput and press enter.
- With DirectInput selected, go to Edit->New String Value. Name it 'MouseWarpOverride' (without quotes) and press enter. Now right click it, and select 'Modify.'
- An Edit String box will appear with the value name 'MouseWarpOverride'. In the blank Value Data box, enter 'force_edge' (without quotes). Click ok.
- With these changes, you can now exit the Registry Editor and close the Run Command dialog.
Thank you to Ken Thomases for this trick.
