NrG-MoDz wrote At the main menu press LT and RT untill stood up.
Then walk over to the computer and type in the codes.
The computer is behind the chair.

In order to access the terminal, Mason must be out of the torture chair. Once hes free to walk the room, head over to the left and press X or Square for access on the Terminal.

Enter the following cheat codes to unlock the following:

UNLOCK ALL INTELS By entering the code below, players will be able to unlock all intels and let them view it. Please take note that by entering the code, the process in unlocking the achievement or trophy will be disabled.

Code: 3ARC INTEL

UNLOCK ALL LEVELS, ZOMBIES LEVEL, AND DEAD OPSTo unlock all levels in the campaign, zombie and dead ops mode, simply enter the following code.

Code: 3ARC Unlock

PLAY ZORK
Simply enter the code ZORK in the terminal.

Have Fun!!!

I KNOW ANOTHER CODE

Type in the code "DOA" and you unlock an arcade mode of zombies!!! its actually really cool. It'll say insert coin for a while just be patient. please add to original post so more people can see

NrG-MoDz wrote So say if u used 3arc unlock it would give u all the maps and stuuf but would disable the achivment if u completed the campain but u can disable the cheats aswell.

zorrinth wrote What does it mean by i can't unlock a certain achievement?

It will notify you if it will disable achievements. I don't believe that 3ARC UNLOCK disables campaign achievements. If you want to disable a cheat, i'm not sure how, but try typing in the code you used originally or (after this, i am just giving suggestions to try, i have no idea if they work.) try 3arc lock or 3arc disable.
Note: I believe 3arc intel is irreversible, once the achievement is disabled, its disabled for good!

Does The Cheat Always Stay On (After u Stop Playing Black Ops) Or Do u Have to Re enter it Everytime?

if u add a lil more i think this should get a sticky

Nice post
Ill try it now

Nice find man!!!!!!!

which zombie maps does it unlock?

lets say i enter will i always have zombie map even wen turn off xboxc

Heres one more code but you must enter one at a time in order to unlock dead ops.

1st code:CD BIN

2nd code:DOA

There you go try em out this does get you an acheivment.
