Activision just sent word that the Call of Duty World At War Beta has just been released over Games For Windows. If you pre-order at your local GameStop you'll be granted access to the beta which will only last for a few weeks before with the game releasing on November 11th.

The Call of Duty: World at War multiplayer betas will provide players with an opportunity to play up to Level 40 as U.S. Marines, German Wehrmacht, Japanese Imperial Army and Russian Red Army factions in a variety of game types (Team Death Match, Free-For-All, Capture the Flag and War), across three different maps: 

• ·         Castle: The Imperial Japanese Army faces off against the Marine Raiders in a daytime battle, located on the grounds of an ancient, Japanese castle.
• ·         Makin: The U.S. Marine Raiders square off against the Imperial Japanese Army in a nighttime fight, set in an outpost on the Makin Atoll in the Pacific.
• ·         Roundhouse: The Wehrmacht will fight the Red Army to the bitter end in a daytime struggle that features tank and infantry combat, set in a desolate, war-torn European train depot. 

The Games for Windows beta will last for a few weeks; however, the full battle will begin on November 11, 2008 when Call of Duty: World at War is released to retailers nationwide.
