How to get Dead Ops Arcade Games.
At the title screen, move your analogue stick so you're looking down at your arms.
Then press L2 & R2 - you'll notice the character starts to struggle. Simply continue to struggle until you're character has broken free of the straps.
Then walk around the room until you find an old computer. You'll see a prompt saying "press and hold square to activate" - do that, then using the keyboard, enter in DOA and then hit enter.
Congrats, you've just unlocked the Dead Ops arcade game.
