Beginning today, Friday March 6th through Monday March 8th, Call of Duty World at War is offering Double XP points. This includes Xbox 360, PLAYSTATION 3, PC, and the Nintendo Wii.. This Double XP weekend comes a week after the latest Map Pack of Makin Day and Call of Duty 4: Modern Warfare double xp, so those who are still playing COD4 will finally want to move over. We love our weekends and when you throw in a COD 2x XP, only a Pee Wee’s Playhouse marathon can draw me away. Thank You Treyarch!
