Another day, another mini-game unlock.

We’ll keep this one short, since we’ve been through a bunch of mini-games already.  Zork is a text based mini-game that can be played through Call of Duty Black Ops.  To unlock it, as usual, start by opening the computer terminal for entering cheats first.  Then, enter the code “Zork” or “Hello Sailor” (either one will work) and hit execute.  Now the Zork game will be available to you, and as an added bonus you can unlock the “Eaten by a Grue” achievement by playing it.  Huzzah!
