Zork Zero: The Revenge of Megaboz is an interactive fiction video game, written by Steve Meretzky over nearly 18 months and published by Infocom in 1988. Although it is the ninth and last Zork game released by Infocom before the company's closing, Zork Zero takes place before the previous eight games (Zork I, Zork II, Zork III, Enchanter, Sorcerer, Wishbringer, Spellbreaker and Beyond Zork).
