Call of Duty Modern Warfare 3 Double XP until Tuesday

Now is the time to get that perk and weapon unlock you've been working towards.

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.
