Treyarch is giving everyone another Double XP Weekend starting tomorrow, March 4th, at 10AM PST / 12PM CST. It will end Monday, March 7th, at approximately 10AM PST / 12PM CST.
This Double XP Weekend is on all platforms (Xbox 360, PS3, PC and Wii). You will see 2x the normal earn rate of XP & COD Points. This Double XP Weekend is largely due to the fact that today the first map pack Xbox 360 users saw a month ago, came out today for the PS3 only at the moment. PC and Wii are still coming at an unannounced date.
