Several treasures and locations in Zork reveal that there used to be a large aristocratic family called the Flatheads, who reigned supreme over the GUE. FrobozzCo products are littered throughout all Zork games, often to humorous effect.

The dungeons are stocked with many novel creatures, objects, and locations, among them the ferocious but light-fearing grues, zorkmids (the GUE's currency), and Flood Control Dam #3-all of which are referenced by subsequent Infocom text adventures.įrobozzCo International is a fictional monopolistic conglomerate from the game. The goal is to return from exploring the "Great Underground Empire" (GUE, for short) alive and with all treasures needed to complete each adventure, ultimately inheriting the title of Dungeon Master. The player is a nameless adventurer "who is venturing into this dangerous land in search of wealth and adventure". Zork is set in "the ruins of an ancient empire lying far underground".

Zork was directly inspired by the first text adventure game, Colossal Cave Adventure, written in 1975. The game has since been ported to numerous systems. The three titles released commercially were Zork: The Great Underground Empire – Part I in 1980 (later known as Zork I), Zork II: The Wizard of Frobozz in 1981, and Zork III: The Dungeon Master in 1982. The four founded the company Infocom in 1979 and released Zork as a commercial game for personal computers, split due to memory limits of personal computers compared to the mainframe system. It was originally developed by four members of the MIT Dynamic Modelling Group - Tim Anderson, Marc Blank, Bruce Daniels, and Dave Lebling - between 19 for the DEC PDP-10 mainframe computer. Zork is an interactive fiction computer game.
