Call of Duty: Black Ops – how to unlock Dead Ops Arcade and other Easter eggs from the main menu

Call of Duty: Black Ops is full of hidden modes and secret codes – what's surprising is how many of them are available as soon as you start the game. Wondering where to find the third version of Zombies? Want all of the intel information without having to locate all of the intel? Tired of being stuck in that stupid interrogation chair, and wish you could escape? Here's how…

In the main menu, don't just sit there. Alternately pull the Left and Right controller triggers, as quickly as possible – LEFT RIGHT LEFT RIGHT LEFT RIGHT LEFT RIGHT LEFT RIGHT LEFT RIGHT, etc – to break free from your restraints, earn an Achievement / Trophy, and explore the interrogation room at will.

Now head to the back of the room and find the interactive computer terminal in the corner. Access it, then enter "DOA" at the prompt to unlock Dead Ops Arcade, a retro top-down, two-stick shooter reminiscent of Smash TV and brimming with old-school zombies and rabid monkeys. You can now play this mode anytime – solo or co-op – by looking under the Zombies menu.

That's not the only secret this computer holds, however. You can also type the following codes:

"3arc Intel" – Instant access to all of the censored information under the Intel menu, normally obtained by locating the 42 intel items scattered throughout the missions. Warning: This shortcut will void your chance at earning the intel Achievement / Trophy.

"zork" – Play a 30 year-old text adventure game! No, really, the whole thing! We'd recommend plugging in a USB keyboard if you're serious about doing this.

"help" – Shows what other command prompts are possible. You can read letters from Mason's family, look at concept art, listen to soundtrack music and attempt to break into other government agencies' databases.

    How do you free him on the wii? Z is the left trigger button and B is the right trigger button. But B is also the back button and when I press it, it takes me back to the main menu. Can anybody help?

    When you have freed yourself from the chair and go to the back of the room and unlock the dead ops arcade mode, you will also unlock the 3rd zombie mode which is the same mode as the arcade mode. But then you can play it with 4 players for the people who didn't know it.

    to get free from the chair on ps3 it is r1 and L1 and on xbox 360 its lt and rt dont know about the pc though. On computer there is alot more stuff than just unlocking all levels (campaign + zombies) = 3arc unlock , and all intel = 3arc intel there is all sorts of pictures sounds and letters for example type in cat derriese1.pic, cat dad-letters1.txt (could be without s in letters)

    I love it when games do this kind of stuff. MORE, PLEASE!

    @ogmonster, the triggers on PS3 are L2 and R2
  • ogmonster - November 9, 2010 10:01 p.m.

    Does this work for ps3? I cant seem to get it to work! When you say the controller triggers i'm guessin you mean the analogue sticks.

    I love these kind of Easter Eggs. It reminds me of the carrington institute from Perfect Dark, or like the Cheats/Hacking menu from the first Matrix game on the Xbox.

    @ RadimirWackytov Hey Im just guessing cause I know nothing about the PC version, but try the aim/shoot buttons/commands? Or are those the mouse buttons or A-D keys? If it is sorry, just making a suggestion. Good luck.
  • AxiamWolfe - November 9, 2010 11:58 a.m.

    They included the whole of Zork on that little computer within a computer/console? Gotta give them credit for that.
  • RadimirWackytov - November 9, 2010 11:28 a.m.

    Is there any way to achieve this on PC? I've tried with the left-right mouse buttons, the A-D keys, the left-right keys - Is this just a console exclusive, or am I doing something wrong?

    Going to try this now
