EDIT:
For all of you who think Nazi zombies is impossible the game is set in the cold war.
The cold war started in 1947, less then 2 years after world war 2 ended, and if you think Vietnamese zombies, you could be right but remember, this game is developed by Treyarch.
And for those who argue further read this.
In call of duty world at war, the first map was an introduction to Nazi zombies, the only real story behind it was they were carrying cargo on a plane when they crashed into an airfield, half the crew died in the crash, and some of the others that survived were killed by the savage zombies, the other made their way to an abandoned airfield base, that's where the game begins. Next is the asylum where dr, richtofen started before he was hired to mess with 115, then shi no numa where you can actually see 115, and then der riese where it all started.
The storyline hasn't completed yet, they've left it wide open now for a good 11 months since der riese was released, I believe they stopped developing maps when they secured Black ops and new they would be developing black ops, hence the story continues.

Watch this
If you dont understand, on the black ops poster their is a number, if you call that number you get the mystery box sound.
18773804270 (The number)
