How do you get Call of Duty World at War zomhies on Call of Duty Black Ops?

The only way is to have purchased the hardened edition and it only was available for the Xbox 360 and PS3 even if you purchase First Strike and get the Maps including a zombie map it is not the Call of Duty World at War 4 extra maps from the game and 3 map packs but a new one. Maybe they will sell them in the future but nobody has said if or when

to get waw Zombies you have to type in 3ARCWAW and you will get zombie waw maps on black ops
