Pocket Lint writes: "The development of the Call of Duty series is a touch odd. Infinity Ward (Call of Duty 1, 2, and the stupendous 4) trade design duties with Treyarch (Call of Duty 3, and 5) to make sure a new one hits the shelves every holiday season.
Unless you've been living under a particularly sturdy rock, you'll be well aware that Call of Duty: World at War heads back to the series' starting point. Namely, World War II. And as such, all those new fangled weapons, and snazzy kill streak bonuses fail to make appearances".
