Yea the only way you can get the nuke town zombies is if you get the hardens wich is 79.99, or the prestige wich comes with the care package. You won't even get it if you ore order the Game .
That is kindave stupid if you ask me. They should have attached with elite premium membership or something that more people would buy. I have been reading the news on the Black Ops site and it seems like the other posters may be right.
