These things are certainly becoming popular, we guess devs discovered that people like getting twice the reward for normal "work." Last time the event was the release of COD4's first map pack. This time it's the same thing, only for PS3, and since the maps are already out on 360, we get the Double XP Weekend too. The specific start and stop times for North America are from 12:01 AM on Friday, April 25 to 11:59 PM on Sunday, April 27. And for those European gamers the Double XP Weekend is completely different, beginning at 12:01 AM GMT on Friday, May 2 and concluding at 11:59 PM GMT on Sunday, May 4. Mark your calenders gamers!
