The Spacing Guild expansion introduces a Space Board where Guild Heighliners will race through space to bring reinforcements to Arrakis, as well as one Heighliner Board for each faction, where players will stow the reinforcements they?re able to get from the Imperium forces and send hurtling across space to deploy at Arrakis.

Players are able to perform special Imperium Actions throughout the game, in order to coax either the Spacing Guild, CHOAM, or Landsraad to help them in their plight.
