This is not for the original zombie maps but if you are looking for a new zombie map follow these instructions:

1) Buy an Xbox 360

- If you already own one, skip to step 2. If you don't want to buy one, wait one month, then follow the rest of the instructions starting at step 3.

2) Wait ONE day (June 28th)

3) Go to the XBL Marketplace and purchase the COD:BO Annihilation map pack for 1200 MSP ($15)

4) Enjoy your new multiplayer maps, and your new zombie map, Shangri-La.What is the code for the zombie maps on COD black ops hardend adition?
"The code" is not the same code, everyone get's a different one. And seriously i doubt anyone will give you somthing they spent extra money for. If you want to play them so bad go buy World at war.What is the code for the zombie maps on COD black ops hardend adition?
