If you've played Red Dead Redemption, you should recognize this. For those of you who haven't, Deadeye is a way to briefly slow down time to let you aim more accurately. If you want to shoot multiple people, you can press right bumper to place a red "x" where you want to shoot them. Oh can then press right trigger to shoot all of the x's. This is a filter test, made to look like the Deadeye aim. What do you think?
