so this will explain why head glitching occurs in the BO2. this best way to beat a head glitch is avoid head glitching spots. check out Drift0r on youtube he covers each map with all head glitching locations. i'm sharing this is so you guys understand why this happens and you can avoid the spots.
if people are satisfied with cheesing other people to do well that's there problem but they might as well go get a modded controller cause they have about the same amount of skill as those people. none.
