Unlocking Zombie Maps in Call of Duty Black Ops?

Question

For the PS3 Call of Duty Black Ops, is it possible to unlock the "Ascension", "Call of the Dead", "Shangri-La", and "Moon" maps without having to buy them?

I've broken out of the chair at the start screen, is there any code to put into the terminal that will unlock these levels?
