Zork III: The Dungeon Master is the third installment in the Zork series of interactive fiction games, developed by Infocom and released in 1982. It continues the text-based adventure format of its predecessors, requiring players to input commands to explore, solve puzzles, and progress through the game. The story follows the player's journey to confront the Dungeon Master, a mysterious and powerful figure who tests the player's wisdom and resourcefulness.
The game was written by Marc Blank and Dave Lebling, key members of Infocom's development team, though the original query mistakenly attributes it to an unknown author. Zork III was designed to run on multiple platforms, including the Commodore PET, Apple II, and IBM PC, among others. It was praised for its intricate puzzles, atmospheric storytelling, and innovative use of the text-based medium.
Zork III is considered a classic in the interactive fiction genre and is part of Infocom's broader legacy of pioneering work in computer gaming. The Zork series, including Zork III, has influenced countless adventure games and remains a significant part of gaming history. Infocom's games, including those for the Commodore PET, were known for their portability across systems due to the Z-machine virtual machine, which allowed the same game to run on different hardware.
