If your referring to the WaW map packs then you can either be invited to a game that one of your friends have or buy the prestige edition or the hardened edition
Do you mean Black Ops Rezurrection upgraded WAW Zombie maps because the World at War original maps do not play on Black Ops.
In Call of Duty: Black Ops 2, you cannot play all the zombie maps from Black Ops 1 and World at War directly within the game. However, Black Ops 2 includes its own set of zombie maps, along with a specific mode called "Tranzit," which features various locations. Some classic maps from previous games, like "Nacht der Untoten," "Diner," and "Farm," are reimagined within the Tranzit mode, but the original standalone maps from Black Ops 1 and World at War are not included. For those, you would need to play the respective titles.
still play
your disc is scrached
There are 14 maps on Black ops when you first get it.
Yes you can, and more. I love Nazi Zombies, and i have downloaded all of the maps for it on the pc. Not only that, but some people custom build maps and post them on the internet, i have about 20 Nazi Zombie maps, and there is probably plenty of multiplayer maps as well.
If you mean the old Nazi zombie maps then you need the code from the Hardened Edition, but if you are referring to the multiplayer maps, it is impossible to play them on Black Ops unless they are brought to us in a new map pack.
You can only buy it online. But you can play the maps offline there after.
The hardened edition lets you play on the zombie maps from WaW
Black Ops zombie maps do not work on World at War and the only ones from World at War that work on Black Ops are those that were modified for Black Ops and are not the same maps used for World at War and even have different Weapons for the Black Ops game
Unless you have a PC version of the Black Ops game you need to buy them from Playstation Store or from Xbox and you need the Black Ops game to play the 4 Black Ops DLCs that are not just Zombie maps.
No they have different perks for Black Ops II. None of the original maps will work in the new game and they are not making any of the 11 Black Ops Zombie Maps into versions for Black Ops II
