Hackers in Call of Duty: Modern Warfare 2 have figured out the ultimate win: stealing XP. The new glitch in the game causes players killed to lose all of their XP and send them back to Level 1, and the killer gains 5,000,000 XP.

The glitch appears to be only on the Xbox 360 and might only work in hacked, private matches. This is all according to some forum posts and a video posted on YouTube.

We’ll keep an eye out for word from Infinity Ward who has been contacted about the matter.
