Deeper in the Great Underground Empire lives the Wizard of Frobozz, half-forgotten and still dangerous: his spells turn up when you least want them. Gardens, a bank, a dragon and a princess wait below. Collect the treasures and score all 400 points.
Zork II is a text adventure: the game describes where you are, and you type what to do in plain English. Your game stays on this device: come back later and it is where you left it.
Zork was written at MIT in the late 1970s and released by Infocom as three games from 1980 to 1982. In November 2025 Microsoft released the source code of Zork I, II and III under the MIT license. RetroGM runs the original story files, unchanged, in JSZM, a public-domain interpreter.
