Is Call of Duty: World at War perfect? Far from it. Is it an action-packed, gritty, gory World War II shooter that anyone can enjoy? Why yes, yes it is. While it is devoid of some of the elements that pushed Modern Warfare to its tremendous success, it's a solid entry to the Call of Duty series. It goes a long way in presenting the case that the second (and hopefully last) world war was one of the most violent and harrowing experiences the world has ever faced. If imitation is the sincerest form of flattery, then Infinity Ward should consider putting out a restraining order on Treyarch.
If you enjoyed Modern Warfare or FPSs in general, this is one of the higher quality shooters you'll find this year. If you're not a fan of grit and prefer your war games more sanitized, such as in Halo, then you'd do well to steer clear.
