Call of Duty: World at War completely changes the rules of engagement by redefining WWII gaming and thrusting players into the final tension-filled, unforgiving battles against a new ferocious enemy in the most dangerous and suspenseful action ever seen. Treyarch will be taking Call of Duty players deep into the South Pacific and European theaters, a gritty fight that will pit players against enemies that know no surrender and show no mercy.

Powered by Call of Duty 4: Modern Warfare technology, Call of Duty: World at War brings an uncensored edge to combat, as soldiers face the most harrowing and climactic European and Pacific battles in which an enemy, who knows no surrender and no retreat, will fight to the last breath, unleashing an arsenal of lethal surprising tactics. Peril and danger lurk throughout the battlefield as players combat the unknown risk of the new chaos of battle.

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.

Reinforcements are scheduled to arrive for one of the most-played online multiplayer games, as Activision Publishing, Inc. and developer Treyarch, confirmed plans today to deliver Call of Duty: World at War Map Pack 3 in August. Map Pack 3 will feature three multiplayer maps ("Battery," "Revolution," and "Breach"), co-developed with partner Certain Affinity, and one new Zombie map ("Der Riese"), for the Xbox 360 and PlayStation 3.

Call of Duty: World at War Map Pack 3 is scheduled for release in August.
