You can escape the main menu of Black Ops to find a computer terminal, which can be used to input unique codes and commands. While some codes can give you free unlocks (like Five, a Zombies map), others can be used for mere fun and games, and others have juicy lore related to the Campaign and Zombies mode! Here's a full list of all codes and what they do.

How to Input Computer Codes in Black Ops

When you're in the main menu screen, which is where Alex Mason sits restrained in a chair and has the option to select Campaign, Multiplayer, and Zombies, you can actually break out. All you need to do is repeatedly tap L2 and R2, and you will break free, and you can now roam the room.

Behind the chair where you were restrained is a computer terminal, and you can access it with Square. At the terminal, there's a list of commands and cheats you can input with the keyboard, which include the following:

Inside the Dreamland server, you can enter "DIR" or "LS" to see unique files, which can be images and text files. You can then read said file with "CAT" (for example: CAT giant1.txt).

The Dreamland server allows you to read emails, view texts, and images, which are all related to Zombies!
