This is not a showcase of skill... PC is (was?) full of hackers and this is what it takes to have a fighting chance. I did however legitimately prestige 10 times using different weapons through out each run... That got boring so I started sky tubing (I put a lot of work into finding landmarks to line up the cross hairs on the m203 in order to rain bombs down on popular camping spots.) Don't be hatin :P
