World at War

Call of Duty: World at War “will feature a more mature theme than previous installments in the series — swimming elements will be introduced to the series for the first time in single player and multiplayer.” Videos after the break. Click here for first picture in gallery.

While in water, the player cannot sprint and will only move at half speed. Flamethrowers, first introduced in Call of Duty: United Offensive, will be reintroduced with new flammable environments.
