"The Nazi Zombie co-op map, Nacht Der Untoten, was a revelation in Call of Duty: World at War. Killing zombies is plain fun. Add in the World War II setting and creepy atmosphere, throw in a little strategy and Treyarch had themselves a hit. The expansions for WaW saw three additional maps added to the mix. All three offered brand new surprises and weapons, mixing up the formula enough to keep the rabid fans coming back for more.
In Black Ops, Treyarch upped the ante with an additional five maps, one of which was a top down shooter, just to mix it up a bit. I’ve played the ever-lovin crap out of them all. Now, for the sake of argument and my amusement, I shall rank them 1 through 9."
