From the official Call of Duty forums :
Hey Wii gamers,
We are listening to you and continue to work on updates to the game based on your feedback.
You must have a Wii Shop Channel account in order to download certain updates. Visit http://www.nintendo.com/consumer/systems/wii/en_na/channelsShop.jsp#access for information on the Wii Shop Channel.
The game will prompt you to download the update when you start Multiplayer once it is available. If you are already running the game at this time, switch to Single Player and restart Multiplayer to get it. The update cannot be downloaded from Zombies, and you will be prompted to switch over to Multiplayer in order to access it.
