Stop me if you've heard this one: a Russian and an American walk into a Japanese zombie swamp. They have some amusing banter. Being outdoors, they seem to have much more freedom of movement than their compatriots in the farmhouses of France and asylums of Germany. They smash zombies with a giant thresher of some sort. Randomized cola machines give them various power-ups. They get some sort of fancy new electric zapper ray gun. Flaming hellhounds charge them. And many zombies are slain in the process.

Get a glimpse of it all in the trailer above. Obviously the folks at Treyarch are starting to appreciate the Nazi Zombie part of their game as more than just an amusing little coda. The Japanese zombie swamp will be part of a map pack for Call of Duty: World at War due later this month.
