Activision has released a new trailer from Call of Duty: World at War, a new first person shooter sequel developed by Treyarch Invention. Call of Duty: World at War will take place in the Pacific theatre (and partially in Russia's advance into Berlin). For the first time in Call of Duty's campaign 4-player co-op is supported over Xbox Live - and it supports meta game perks as in CoD4's online mode. Call of Duty: World at War will be available in North America on November 11, 2008, and in the UK on November 14, for PC, Xbox 360, PS3 and Wii. In related news, Activision announced that Call of Duty: World at War Xbox 360 Multiplayer Beta has gone public and is now open to everyone (and doesn't require a token). You have to go to Xbox Live Marketplace; find Call of Duty: World at War in either the "New Releases", "Games", of "Demos" section of Xbox Live Marketplace; click on CoD: World at War and you will see the Multiplayer Beta available; download the Beta.
