I take it you are all enjoying Black Ops’ Zombies Mode? Well, a number of people may have been happily playing along on Kino Der Toten – and the World at War Zombie maps should you have purchased a Hardened or Prestige Edition – not realizing that there is another secret Zombie map for you to play on!
This extra, “secret” Black Ops Zombie Map is called Five. It is set in The Pentagon and is full of crazy Zombie goodness, has you playing as one of 4 Presidents and, in my opinion, is better than Kino Der Toten. You can unlock this map by completing Black Ops’ campaign, but there is a much quicker way! So, let’s get down to unlocking it.
While sitting in the chair at the main menu press LT, RT, LT, RT, LT, RT, continuously until you break free from your wrist straps. Now walk around the back of the bank of monitors to the same computer terminal you used to unlock Dead Ops Arcade , but this time enter the following code; “3arc unlock” (without the “s).
Now when you go to Zombie Mode you will notice the “Five” Zombie map will be unlocked and ready to bust some undead ass. Enjoy.
