I just read about this:
http://www.splitfish.com/?uid=4nkpfqinh2cvv3t0on another forum and am interested in picking it up for my PS3. I am a PC Gamer and am used to accurate aiming with a mouse so I am not that good at console FPSs at least not enough to really win any tournaments or anything like that. But, this might help. Though I read people are being accused of cheating because they now aim much better.
