I've been trying to set up a decent splitscreen setup for obvious splitscreen playing reasons, but I want to use the mouse on one player, but is there a way to disable it on another player so the second (and third and so on :P) players can just use the keyboard to look, and not have my mouse movements throw their aim off? If there isn't a way to do so, I can deal with just keyboard-looking for everybody, even though it might be lots of fun to set up a comfortable layout! :P
