Leave your packs and bring extra ammo, as you head to the South Pacific and European theaters for Call of Duty: World at War - a gritty fight that will pit players against enemies that know no surrender and show no mercy. Utilizing the Call of Duty 4: Modern Warfare engine, Call of Duty: World at War throws out the rulebook of war to transform WWII combat through a new enemy, new tactics and an uncensored experience of the climatic battles that gripped a generation. As U.S. Marines and Russian soldiers, players will employ new features like cooperative gameplay, and weapons such as the flamethrower in the most chaotic and cinematically intense experience to date.

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.
