Microsoft announced today that they’re preserving a bit of history here - with Zork I, Zork II, and Zork III now officially and clearly open source. The source has been around for a while but now it’s all proper.
From the announcement they said:
Today, we’re preserving a cornerstone of gaming history that is near and dear to our hearts. Together, Microsoft’s Open Source Programs Office (OSPO), Team Xbox, and Activision are making Zork I, Zork II, and Zork III available under the MIT License. Our goal is simple: to place historically important code in the hands of students, teachers, and developers so they can study it, learn from it, and, perhaps most importantly, play it.



The commands aren’t very complicated. You’re mostly looking at stuff, taking stuff, or using items on stuff. It’s usually just [verb] [noun] type simple 2 word sentences.
The hard part of Zork is figuring out where to go and what to use where. Navigation in the game is usually by compass directions but the map is not a plain grid, so you can go north and then go west and end up right back ever you started for odd reasons. You’re highly encouraged to make your own map on paper, in addition to lots of notes about things you saw in each area.
The game even includes a maze, a reference to the earlier Colossal Cave Adventure’s “maze of twisty passages, all alike.” Navigating it is a real challenge!
A paper map sounds fun! I’ll try. Thank you for the tips.
