"Beyond Zork (full title: Beyond Zork: The Coconut of Quendor) was an interactive fiction computer game written by Brian Moriarty and released by Infocom in 1987. It was one of the last games in Infocom's Zork series; or, rather, one of the last Zork games that many Infocom fans consider "official" (titles such as Zork: Nemesis and Zork Grand Inquisitor were created after Activision had dissolved Infocom as a company and kept the "brand name"). It signified a notable departure from the standard format of Infocom's earlier games which relied purely on text and puzzle-solving: among other features, Beyond Zork incorporated a crude on-screen map, the use of character statistics and levels, and RPG combat elements. It is Infocom's twenty-ninth game."
