Short answer

Dune II (1992), Westwood’s real-time strategy pioneer, runs natively on modern PCs through two open-source engines. OpenDUNE recreates the original. Dune Dynasty (latest 1.6.4, 31 May 2025) builds on it with widescreen, Command & Conquer-style controls, skirmish and multiplayer, for Windows, Mac and Linux. Both need the data files from your own copy of Dune II 1.07.

What it is

Dune II: The Building of a Dynasty (Battle for Arrakis in Europe) came out for DOS in 1992 and set the template for real-time strategy. It needs DOSBox today and has notoriously clunky controls: one unit at a time, no queues.

OpenDUNE is “an open source re-creation of the popular game Dune II”, which “attempts to re-create the original game and apply modern technology to it to allow it to be run natively on most operating systems” (OpenDUNE README). It is written in ANSI C on SDL and supports Windows, Mac, Linux, FreeBSD, and even Atari TOS, OS/2 and Haiku.

Dune Dynasty “builds upon the original game engine as reverse-engineered by the OpenDUNE project”. Its README stresses: “It is not a remake.” The goal is to make Dune II playable on modern systems with extra features, fixes and quality-of-life changes. The current GitHub project continues an abandoned SourceForge project.

How setup works (overview)

  3. Start Dune Dynasty and pick a house campaign, or a skirmish.
  4. Adjust scaling, controls, music sets and optional gameplay changes in the options.

What Dune Dynasty adds

From its README:

  • Graphics: high-resolution widescreen, separate scaling for menubar, sidebar and map for HiDPI displays, aspect-ratio correction, optional smoother unit animation.
  • Controls in Command & Conquer style: build from a scrollable side panel, queue multiple items, drag-select units, double-click to select all units of a type, control groups, rally points, mouse-wheel zoom, touchscreen support on Windows.
  • Skirmish and multiplayer: up to six human or AI players, custom alliances, random maps, and three extra factions (Fremen, Sardaukar, Mercenaries).
  • Sound and music: emulated AdLib, MIDI through FluidSynth, and external music sets ranging from recorded MT-32 and Sega Mega Drive versions to film soundtracks, with an in-game jukebox.
  • Optional gameplay changes: health bars, fog of war, a brutal AI, higher unit and structure limits, start level selection.

Which one to pick

For the game exactly as it was, OpenDUNE. For Dune II with modern controls and extras you can switch on or off, Dune Dynasty. For a full remake of the Dune RTS formula, see OpenRA, which includes Dune 2000.
