Multiple versions of Hunt the Wumpus were created and distributed after the game's release. Yob made Wumpus 2 and Wumpus 3, beginning immediately after finishing the original game, with Wumpus 2 adding different cave arrangements and Wumpus 3 adding more hazards.[1][8] The source code for Wumpus 2 was published in Creative Computing and republished in The Best of Creative Computing 2 (1977), along with a description of Wumpus 3.[5] The PCC announced in the same November 1973 newsletter issue as it discussed the original game that a version from them titled Super Wumpus would be available soon, and listed it in its order catalog in its January 1974 issue.[4][9] In 1978, a book titled Superwumpus, by Jack Emmerichs, was published containing source code for both BASIC and assembly language versions of his unrelated version of Hunt the Wumpus.[10]
