i you have auto look centering or whatever enabled, then whenever it is up, you are always looking at eye level, and as long as the floor is even, you can snipe anyone with only lining it up left and right! i tested this, and you can really move anywhere, scope in, and always be right on their head level! of course, you would have to deal with walking around with your reticule always moving places you don't want it to... any ideas, questions???
Hmmm, good point, I have thought of that before. However do you know how hard it is to turn the stick right and left only and not just a little up and down, PRETTY DANG HARD. I will try this when I get home, although most maps aren't straight up flat.
