Cheat Codes:

At the main menu, use the Right Analog-stick to look down at your hands
and see you are locked up. Repeatedly press LT + RT to escape from the
chair (unlocks the "Just Ask Me Nicely" secret achievement). After
breaking free, move around to the area behind your chair to find an old
computer terminal you can use to access the Central Intelligence Agency
Data System. Type one of the following codes to access early unlockables
and hidden features in the game. *Note:* You can also plug a USB
keyboard into your Xbox 360 to enter the codes and play the Zork
text-based adventure game.
