Take part in one of the most famous science-fiction stories of all time.

It has the same beloved DNA, flavor, tension, and themes, but with new game-board design, more spice, new streamlined rules, and a new market deck from which you can purchase game advantages. Also, the brand new two-player mode really opens up new gaming opportunities, all making the game more accessible for even the most casual gamer. In Dune, you will take control of one of the four great factions-House Atreides, House Harkonnen, the Fremen, and the Imperium-all vying to control the most valuable resource in the universe: melange, the mysterious spice only found at great cost on the planet Dune. Ship your forces to Dune, harvest spice, seize control of strongholds, and destroy your enemies. Who will control Dune? You decide!

On the Shipping and Movement Phase, players take turns adding forces to the board and then moving forces on the board. Each player's faction has The game plays 3 to 5 Rounds. Starting on Round 3, the game can end if a player occupies 3 strongholds at the end of the Round. If no one occupies 3 strongholds at the end of Round 5, then the player with the most spice wins (and each stronghold they occupy counts as 5 spice).
