As mentioned in my article for the new CALL OF DUTY: WORLD AT WAR map pack, players will get to enjoy double experience points as soon as the pack comes out. The new maps will be available this on the 19th, which is this Thursday. World at War Map Pack 1 will cost about 800 microsoft points (10 bucks). This is good news for all. Online players will be able to level up much faster while playing on the new maps. Treyarch really knows how to please their fan base. The double XP dates are from March 19 - March 25.
