Emperor: Battle for Dune

Emperor: Battle for Dune is the true sequel to both Dune II: The Building of a Dynasty and Dune 2000. Unlike Dune 2000, it progresses the storyline and takes place after the Ordos victory in its predecessors, but with the same basic premise: houses Atreides, Ordos, and Harkonnen battle for supremacy on the planet Arrakis, the only location where the valuable resource known as Spice Melange can be found, but for the first time in the Dune RTS series, other locations are also visited briefly.

This time, all three factions have redesigned arsenals with more varied units. Other than a new 3D engine by Intelligent Games, Emperor: Battle for Dune introduces the sub-house system. In skirmish and multiplayer games, up to two (out of five) sub-houses can be chosen to lend their technologies to the player in the form of two unique units and a relevant structure which trains them. The singleplayer campaign is once again played on a meta-map, this time with defensive missions as well, and sub-houses may join the player in the fight. The Living Planet feature randomly spawns tornadoes. The AI's play style can also be chosen in skirmish and multiplayer modes for a more varied gameplay.

Each refinery now comes with a free carry-all assigned to the existing free harvester for faster resource gathering and defense. Also, each refinery can be upgraded with two extra pads which also come free with a harvester and carry-all.

True to a major Westwood Studios production, Emperor: Battle for Dune features live-action cutscenes between missions.
