Microsoft has wiped the Gamerscores of people cheating at Gears of War 2.
"As part of our regular safety monitoring we have pinpointed a group of players who have unlocked specific Gears of War 2 Achievements through an unauthorized hack," said Larry "Major Nelson" Hryb on his blog.
"As I have mentioned in the past, this is something we do occasionally to keep the service free of cheating in order to maintain a fair and level playing field for everyone," he added. "If you play fair and earn your achievements without glitching or cheating, you have nothing to worry about."
Call of Duty 4 - another of Xbox Live's most popular pursuits - also aims to outlaw cheaters. Infinity Ward's outspoken Rob Bowling confirmed via Twitter that a new COD4 patch will "eliminate the cheaters".
You're only cheating yourselves.
