I don't know many but I know 3ARC UNLOCK will unlock all levels including five, a zombie level. And DOA unlocks an arcade version.
i am really sorry to tell you this but you cant you have to get map pack or something else but i wish there was a code to unlock all zombie maps on the wii
to get more zombie maps, you need to get the fourth expansion pack, on GameStop it costs 15 bucks
type in 3ARCUNLOCK in the computer terminal and for dead ops arcade type in doa instead.
DOA -unlocks Dead Ops Arcade. 3arc unlock -unlocks everything 3(trey)arc! =.=

I've been looking around online, and it says that you can't unlock the other 2 levels for the wii, you can only have the one map that is included when you start the game.
