Call of Duty: World at War is the fifth major installment in the series and the second to be developed by Treyarch who was also responsible for Call of Duty 3, a console-only version of the game.
Considering the high expectations built around this release it will be interesting to see how 'World at War' stacks up against other competing shooters, but perhaps most importantly how it compares or improves upon last year's Call of Duty 4: Modern Warfare, which was developed by the series creator Infinity Ward and was an all-around success on the PC platform.
