Zork is a text-based adventure game based on the early computer game from 1979 and can be played on the computer terminal in Call of Duty: Black Ops and Call of Duty: Black Ops Cold War by typing zork into the blank text prompt.


Being a text-based adventure game, Zork contains no graphics and only text to describe what happens. This can prove to be difficult in times of little description.

Zork commands

After starting the in-game text-based retro-game Zork, either through entering zork or hello sailor, these are the commands a player can type into the computer terminal's console to play the game. This is not an exhaustive list.

The start-up screen displays the following information:
