3arc unlock and DOA in computer unlock the second and third zombie maps
actually it has....you can unlock it by either beating the campaign or by typing in "3arc unlock" in the computer after you get out of the chair (if you dont know how to get out of the chair all you do is keep on pressing L2 and R2 or LT or RT for xbox)
to unlock all three zombies maps you need to return to the homescreen. break out of the chair by tapping LT-RT-LT-RT until you break free. once free you will need to find the computer, enter the computer by pressing X or Square. type in 3arc unlock and walla!
Im not sure, but on ps3 and xbox you have to get out of the chair by pressing both triggers rapidly and then walk over to the computer and click X/A and then type "3arc unlock" then click enter
that is why it is locked!! Now no one can unlock it!!!!!
There are two different ways to unlock the Zombie map called, "Five". The first way is to beat the single player campaign and the map will be unlocked at the end. The second method is while you are at the main menu sitting in the chair alternate pressing the left and right triggers on your controller. This will allow your character to stand up. You will then need to walk behind the chair and access the computer terminal. On the computer terminal you will type in this code: 3arc unlock Once you have entered that code exit the computer terminal and then access the zombie menu. You should see the map, "Five" listed.
