Can I turn off auto aiming (sticky aiming) in the PC version of this game?

For both single and multi player?

its easy. follow these simple instructions. 1) before you start the game go to ...chameleonbob

I found another solution here. You need to either login once to create a new ue3profile file, or copy the default Player.ue3profile file to a new file and select that. After that the game saves as normal in offline mode too.
