OpenRA is a highly moddable RTS game engine for classic Westwood 2D games. In fact Red Alert, Command & Conquer and Dune 2000 are implemented purely as mods on it. Tools are provided that allow you to add new units, maps and tilesets even create your own mod. Have a look at the wiki.

Built-In Mods

Red Alert

sovietsThe RA mod for OpenRA is a reimagining of Command & Conquer: Red Alert. It is not just a clone of the original but has improved and rebalanced gameplay. The UI is modernised for higher resolutions and better usabiltiy. It has fully working multiplayer support for both internet and local play (via direct connect). A single player campaign is currently being worked on.

Command & Conquer

GDI The CNC mod for OpenRA is a reimagining of the original Command & Conquer: Tiberian Dawn game. As with Red Alert modern networking and rendering technology is used. Also new features are implemented such as snow terrain, neutral tech buildings and many glitches from the original have been fixed.

Dune 2000

ArrakisThe D2k mod for OpenRA is a reimagining of Dune 2000. A remake of the remake so to speak. The mod tries to optimize balancing and gameplay. Currently in early stages of development, but already playable. The spice must flow!

5 comments by Milanium on Apr 5th, 2014

Our first playtest of 2014 is long overdue, and marks a significant step forward from our holiday release.

A brief sampling of our full changelog is included below.General gameplay improvements include:

  • Air units can now attack-move and guard other actors.
  • Players can now place beacons on the map to signal teammates.
  • Time-delayed support powers will also place beacons.
  • Unit husks can now be force-targeted and destroyed.
  • Engineers (mechanics in RA) can salvage unit husks to return them to the battlefield.

User-interface improvements include:

  • A new mod selector interface, which now appears the first time you run OpenRA.
  • The offline skirmish mode from Tiberian Dawn has been added to the other mods.
  • Significant UI improvements for spectators and replays.
  • Integration with the OpenRA Resource Center for installing custom maps when joining a game.

Specific mod improvements include:

  • [D2K] Implemented concrete plates, and structural damage for buildings built on the ground.
  • [D2K & RA] Saboteur / Tanya can now place C4 on vehicles.
  • [RA & TD] Tanya / Commando can now place C4 on bridges.
  • [TD] Added several of the original campaign missions.
  • [RA] Added the Allies Phase Transport and and Soviet Hijacker units.
  • [RA & TD] A number of balance changes (see the full changelog for details).

Changes that impact mod and custom-map authors include:

  • Improvements to the Lua scripting API.
  • Removal of the legacy scripted missions.
  • The legacy (RA & TD) map converter has moved from the map editor into OpenRA.Utility.exe.
  • Added --upgrade-mod and --upgrade-map utility commands to automatically upgrade a mod or map targeting release-20131223 to the latest version.
  • A number of trait properties have changed from pixel or cell units into world units. Use –upgrade-mod to automatically convert these.

A significant issue was discovered with our Lua integration late in this playtest cycle. This shouldn’t significantly affect scripted missions, but caused the shellmaps (the animations that run in the main menu) to become unstable after some time. Rather than delay the playtest further, we have disabled the shellmaps until the issue has been fixed. The shellmaps will be restored before the next full release.

We have also been nominated for the Linux Game Awards Project of the Month for May 2014.


If you’d like to help improve the profile of open-source Linux gaming, then be sure to vote for us (or one of our competitors, they are great projects too!).

A brief taste of our new playtest changes can be seen below:

Mod Chooser

The new mod chooser is styled after our website, and better highlights the official and custom mods.

D2K Improvements

Concrete plates have been added to D2K, and the turrets now integrate properly with walls.

Map Beacons

Beacons and radar pings will now notify you, your allies, and spectators of any important events.

Phase Transport

The Allied Phase Transport can transport three infantry, while remaining cloaked from enemy view.

Man! I hope this will have all CnC factions in! Nod + Allies vs GDI + soviets would be EPIC!

Just started playing this a couple days ago because my son wanted to make a midevil RTS type game and I looked for some easy to use RTS engines.

This is a blast. I haven't played CnC/RA in years. Thanks. :)

Have a look at Sleipnirstuff.com where CombineC posted some medieval units in Westwood formats.

Really amazing work you guys have done. This is truly an awesome project and I look forward to seeing what you do next. :)

That being said, there is one thing which, I feel, is a major problem; For the love of God, PLEASE increase the Chrono Tank's teleport-radius!! I don't mind it having a limited range, but it's currently so small that it's completely useless! In my opinion the teleport-radius needs to be AT LEAST 3 times what it currently is so that it can actually do what it was designed to do.

I gotta know, I've been playing D2k for awhile, and haven't seen even the slightest wormsign. Are there sand worms? I have even tried luring them out with repeated tank explosions but nothing. Also it looks like theres the infantry option for thumpers but they're medics instead.

Q: It is compatible with Red Alert 2 Yuri revenge?

By compatible I assume you mean it is built in currently.
The answer is no, not yet.
We are working on many things, one of which is adding support for isometry which will allow TS, RA2, and RA2:YR to be added, in due time.
