PLOT
There is one campaign in the game divided into two: the American campaign and the Soviet campaign. The Soviet campaign is returning after having last been present in Call of Duty 2. There is no British campaign in the game, making World at War the only major Call of Duty set in the Second World War not to feature a British Campaign or a British playable character. It features both a solo and co-op campaign, however both are the same except that co-op is played with multiple people and certain missions are unplayable.
