Dune is a 1992 adventure strategy video game, based upon Frank Herbert's science fiction novel of the same name. Developed by Cryo Interactive and published by Virgin Interactive, Dune blends adventure with economic and military strategy. Loosely following the story of the novel, the game casts the player as Paul Atreides, with the ultimate goal of driving the Harkonnen from Planet Dune, while managing spice extraction, military, and later, ecology through the native Fremen tribes. As the player progresses, his troops are equipped with weapons from "crysknives" to atomics, tap into Paul's latent psychic powers, and get acquainted with such characters from the book as Chani and Liet-Kynes. Released for the Amiga and IBM compatibles, it was one of the first floppy games to be converted to CD
