I am assuming that you have to get a program that allows you to edit maps and stuff like that. It is possible without being a Treyarch imployee because people have made many custom Nazi Zombie maps.
In creative mode you can spawn a zombie with the egg
The Nintendo Wii can only get 3 of the 9 possible zombie maps for Black Ops. see related zombie mode for identification and information on all of the 9 zombie maps
Use the zombie pot and combine ZomGoblin with another ZomGoblin. Edit: This *will* work, but you might get a Zombricaun, now, too.
you can't become a zombie once you die the game is over and you have the option to play again but again you can not become a zombie
You have to harvest crops and zombies for a boss battle
Popcap.
Yes u can I won't tell u how but yes u can make a zombie
Well if you are looking to roleplay a zombie there are many. Like MagicDuel.com, in which you create your character in terms of your actions (the role you get). In it you can even create an avatar for your character and I'm sure it can be a zombie. If you are looking for a specific zombie game, I don't recall playing anything like, in most you kill the zombie :)
