The narrative for the Microsoft Windows, PlayStation 3, Wii, and Xbox 360 versions focuses on the Pacific and Eastern Front theatres of World War II, involving the United States, the Empire of Japan, the Soviet Union, and Nazi Germany. It is told from the perspectives of Marine Raider Private C. Miller, US Navy Petty Officer Locke and Red Army soldier Private Dimitri Petrenko and is based on several historical battles. The multiplayer component of the game contains various game modes and a leveling system that allows the player to unlock additional weapons and rewards as they progress, similar to Call of Duty 4. The game also contains downloadable content called "map packs", which can be purchased online. A new feature to the series was the addition of a cooperative mode, which supports up to two players locally and four players online.
Perfect enemy and friendly chams!
