I found this very cool new idea in UC. I dont have live but i think it should work on live. While playing, just turn on the scoreboard. When you shoot, the accuracy will be near perfect. I think it may be some kind of glitch b/c you can be shooting to the side or even above someone and still be hitting them and killing them. Try experimenting with it and maybe there are other things that you can do like unlimited adrenaline if you activate it will the scoreboard is up...who knows.
