This press release has new details about Call Of Duty: World At War, outlining plans for co-op support and promising flamethrower details (which seem to consist of the fact that the game will include a flamethrower). Here's word on the co-op support, which will allow the chance to do battle in World War II with your band of brothers:

Call of Duty: World at War introduces co-operative play, bringing fresh meaning to the “No One Fights Alone” mantra with up to four-players online for Xbox 360, PS3 and PC, or two-player local split-screen on consoles. Nintendo Wii will also support a unique co-op mode for two players. For the first time ever players will experience harrowing single-player missions together for greater camaraderie and tactical execution. The co-op campaign allows players to rank up and unlock perks in competitive multiplayer by completing challenges and earning experience points, adding continuous re-playability and team-based gameplay. Whether playing competitively or cooperatively – if players are online with Call of Duty: World at War – they will always gain experience points. Based on a player’s experience rank and rank of the player’s friends, Call of Duty: World at War will scale dynamically to provide a deeper level of challenge.
