I have been trying to figure out how rarely someone online will have accuracy that is totally beyond me. On PC I would expect Aimbot but kind of hard to think that is whats up on PS3. Kill cam doesn't show anything outside of what I would expect from a keyboard/mouse user but I doubt some of these people could it off with a controller.
I figured it was rare for people to use a device so they could play with mouse and keyboard but I am starting to wonder now. It seemed like cheating to me but if this is something that is more common then I think I may look into it.
