Modern Warfare 3 double XP weekend has begun on all three platforms, and will come to an end on Monday, April 23rd.
Infinity Ward has kicked off a double XP weekend to celebrate the release of Collection 1 for non-Elite PS3 owners. Now you can start earning double XP until Monday 2am PST (5am EST).
Remember, you can earn quadruple the amount of XP only this weekend when you use your prestige tokens to unlock two hours of double XP.
As some of you have pointed out, today also marks the MW3 Blackout day, where those behind that movement will not play Modern Warfare 3.
