More zombies, more perks, more levels, more weapons, and monkeys. That's what you're going to get with Treyarch's Map Pack 3 for Call of Duty: World At War.

The new Nazi Zombie map adds a plethora of new options including an explosive toy monkey, a bowie knife (with the tag "Now that's a knife") and teleporters for quick escapes (among other new options), while the rest of the pack adds three new multiplayer maps, expanding the game even more.
