For those of you who don’t play Modern Warfare 2 – you achieve 50-100 points for each of your kills, which add to your XP which in turn helps you rank up to earn various guns, perks and game modes. In the video posted below this guy was invited to an XP boosting match, so everyone in the game was cheating already. This guy in particular had an exploit in place that means anyone who kills him gets upto minus 5 million XP each time, affectively reducing their rank back to Private.
