Similar technologies, structures, and units are available to all three, but to each with different balances of strength versus speed and durability versus expense.
With the goal of collecting the most spice (and thus earning harvesting rights for the entire planet), players choose to lead one of three competing galactic dynasties: the mysteriously destined House Atreides, the elusive House Ordos, or the ruthless House Harkonnen. Unlike Virgin Interactive's original Dune, an adventure which recounted the story of Paul Atreides, Dune II is a mission-based strategy game set in the barren expanses of Frank Herbert's famous desert world.
