Call of Duty: World at War is a first-person shooter and the latest installment in the Call of Duty video game series for the PlayStation 3, Xbox 360, Wii, PlayStation 2, DS, and PC.

Prestige mode is an option that a player can choose after they progress through Level 65 (Commander), and it can be accessed in the Barracks menu. Prestige mode effectively restarts a player at level 1. All weapon and other challenges will be reset. The player must progress through the ranks to unlock challenges and weapons again. Despite being reverted back to level 1, the player gains a special symbol next to their name indicating they are in Prestige mode.
