Infinity Ward has announced that all versions of Call of Duty Modern Warfare 3 will be dishing out double XP online until May 29 - that's Tuesday next week.

"Double XP for all ‪#MW3‬ playlists (including all platforms) 5/23 through 5/29," tweeted Infinity Ward.

If you've just bought the second content collection for Xbox 360, you'd essentially be a fool if you chose not to take advantage of the promotion.
