try it out you might be surprised i didnt believe it at first but it saved my ass a few times when i was gettin shot at 1st mlg players use this method and its more effective than plain headshots
edit: the glitches r just for fun i dont expect anyone to actually use them unless they really want to win. oh yeah i SHOULD have two or three special levels that u cannot find normally in my file share i think u can d/l them from the website again they are just for fun
