Hello Tech Game Community,
I am here to tell you can unlock CoD Black Ops Zombie maps without completing the campaign. I am sorry if you already knew about this, but I am just trying to make it general information. Here is a step by step tutorial you can follow to tell you how you can achieve this. Hopefully I helped! Here you go:

Step 1: Load up Call of Duty: Black Ops.

Step 2: Press the start button.

Step 3: DO NOT CLICK ANYTHING! Look down to where you can see yourself tied into a chair with shackles.

Step 4: Quickly press RT and LT until you are released from the shackles.

Step 5: Walk around the room until you find the computer.

Step 6: Press "X" to access the computer.

Step 7: Enter the access code "3ARC UNLOCK" (Make sure ARC and UNLOCK are capital!"

Step 8: Press enter and the code should go through by saying "Cheat Enabled" or something like that.

Step 9: Exit the computer.

Step 10: Go sit back down in the chair with the shackles by standing in front of it.

Step 11: Go to Zombies and enjoy the maps.
