That’s a whole lot of gamers taking on new challenges via the new maps. Of course given the number of units they’ve moved on the game it’s not all that surprising.

Armies of Call of Duty fans have heeded the call and responded with more than one million downloads of the Call of Duty: World at War Map Pack 1 from Activision Publishing, Inc. (Nasdaq: ATVI) and developer Treyarch, during its first weekend of availability (March 19-22) on Xbox LIVE and the PlayStation Network.

The map pack contains four maps (Nightfire, Station, Knee Deep and Verrückt) and is available on Xbox LIVE Marketplace for the Xbox 360 video game and entertainment system from Microsoft for 800 Microsoft Points and on the PlayStationStore for the PLAYSTATION 3 computer entertainment system for $9.99. Call of Duty: World at War is rated “M” (Mature) by the ESRB for Intense Violence, Strong Language, Blood and Gore.
