The popularity of Call of Duty: World at War is once again proved by the number of downloads recorded by the first downloadable Map Pack released by Activision and Treyarch: one million during the first week of availability! And, even if you think that actual owners of the game are much more, it’s still an impressive number for a DLC pack!

“I’m proud that the team at Treyarch delivered an experience that so many people are enjoying,” said Mark Lamia, Studio Head for Treyarch. “We’re excited that the success of Call of Duty: World at War Map Pack 1 will continue to drive the popularity of the game’s Nazi Zombie mode, competitive multiplayer and chart-breaking success online.”

There are no news regarding a “Map Pack 2” yet, but we might be hearing that pretty soon. Until then, if you didn’t get the first Call of Duty WaW Map Pack, you can go grab right now from the Xbox marketplace for 800 MS Points and the PS3 Store for $9.99. You will get four new maps to test your skills on: Nightfire, Station, Knee Deep and Verruckt.
