How do you get all the zombie maps in black ops?

I have five dead ops and these other two but one says I can't play it can someone just tell me all the maps and how to get themHow do you get all the zombie maps in black ops?
First Strike went up for ps3 at the beginning of the month and for xbox feburary 2 i believe, it comes with one zombie map "ascension" and 4 multiplayer maps, the other three zombie maps you speak of are from the game itself and you can unlock those by "freeing yourself from the seat your stuck in at the main menu" by rapidly pressing the L2 R2 buttons. you walk over to the computer and type in 3arc unlock you get all the maps except ascension since it is an purchase required map pack
The new ascension map is from the First Strike pack, so you have to buy that. To get "Five" and Dead Ops Arcade, you can break out of the chair at the menu bu quickly pressing the triggers then go behind the chair and go to the computer. Then type in "3arc unlock". In order to get the zombie maps from World At War, you have to buy the Hardened or Prestige editions of Black Ops.How do you get all the zombie maps in black ops?
well u have "five" and dead ops, so if u dont have Kino Der Toten then try to beat the game and if u want the new map for zombies called ascension then get the new DLC called first strike
you have kino der toten,five and dead ops arcade,if you can't play ascension it's because u didn't buy the first strike map pack!it costs,it's not free!How do you get all the zombie maps in black ops?
buy the hardened or prestige edition for world at war maps(all 4) plus buy first strike map pack. for a total of 8 maps
You have to buy ascension from the ps3/xbox store.
