Call of Duty: World at War is a Wii video game released in November of 2008. It takes place in World War II, much to fan's disappointment after the previous release (Call of Duty 4: Modern Warfare) took place in current times (albeit featured a fictional war).
Gameplay is expected to be similar to the previously released CoD4, which was not released on the Wii. New gameplay elements include the ability to now swim in the water, though your speed will be dramatically reduced and you also won't be able to swim faster as you can on the ground by pressing the sprint button.
Co-op multiplayer has also been included for the first time in the series, and vehicles from the United OffensiveCall of Duty video game had also returned.
