Yes you do.

It started with the Nazi Zombies, but more maps have been added. The Black Ops has 11 different maps available and some are not Nazi zombies but other kinds of zombies
if your talking maps you have to buy them off xbox live
Nazi Zombies (Call of duty World at war) is indeed free. However, you only have 1 map (Nacht Der Untoten) If you want more maps then you must get it by downloading it from XBOX Live or Playstation's online DLC Store. (DLC= Downloadable Content)
Buying the Map packs will also unlock one of the Nazi zombie maps. For example, the map pack 2 will unlock the map Shi no numa.
Probably Xbox LIVE is my best guess.
The Nazi Zombies is over, in black ops 2 they said they were creating a new zombie story line. There will be no more Nazi Zombies.
yes if you are talking about waw then yes. there are a total of 4 zombie maps already and maybe 1 more is to come soon.
nazi zombies will only let you play with two people with no internet, but to play three or more you need to system link with another console, or go on live if you have an xbox
Treyarch may continue making Nazi Zombies with the next Call of Duty. However, nothing official has been announced.
you can mod nazi zombies with a USB or TRANSFER CABLE, and you need to download modio you mod it using your saved game data if you want more help visit youtube a search how to mod cod 5 nazi zombies.
In WaW Nacht der Untoten is the only map you can play without buying the map packs.
As of now, there is no Nazi zombies. This was more the theme of CoD: 5 since the theme was WWII (Therefore nazis.) As of now there is only regular zombies.
