Call Of Duty Black Ops Insert Coin Achievement Guide
From the main menu where you can select Campaign, Multiplayer, Zombies and Options use your Right Analog Stick and look down at your hands then hit repeatedly both the triggers on your controller and you will be released from your chair. Go behind the chair and go to the terminal/computer and hold X after this enter DOA. After tentering DOA it will come up with an arcade screen saying "Insert Coin" i'm unsure how to enter the coin so I just pressed any button and you will unlock the achievement/trophy.
