To celebrate Independence Day in the United States (July 4), Call of Duty: World at War will run Double-XP for the weekend. The weekend starts July 3 at 10:00 A.M. PST, and ends July 6 at 10:00 A.M. PST. The Double-XP is available worldwide.

Also taking place July 3 at 10:00 A.M. PST is a playlist update, where the Map Pack 2 maps will be incorporated into the main Core and Hardcore rotations. Don’t worry though, the Map Pack playlist will remain open for those of you looking to get your fix of the Map Pack 2 maps exclusively.
