Playtest 20191102

We are today pushing a new build that addresses several issues discovered in the previous playtest.

The changes in playtest-20191102 are:

  • Fixed infantry failing to dodge crushes
  • Fixed pilots ejected from killed aircraft remaining in the air
  • Restored ability to force-move helicopters above enemy buildings
  • Fixed several long-standing issues with classic (left-click) mouse controls
  • Fixed 64-bit installation directory on Windows

We are now aiming for a late November stable release, which gives approximately two weeks for any final issues to be discovered with this playtest.

Head on over to our download page to grab the new playtest, and prepare for battle!

The original announcement for playtest-20191021 is included below:


A new playtest is now available for OpenRA’s increasingly poorly named “Summer 2019” release. Thanks to everybody who tested the last playtest, this build should address all the issues and feedback that have been reported so far.

The key changes in playtest-20191021 from the previous playtest-20190825 include:

  • Fixes for several issues with game loading/saving
  • Fixes for several crashes and a desync issue
  • Fixes for several glitches related to unit movement
  • Fixes for several mission related issues in Red Alert and Tiberian Dawn
  • Fixes for several compatibility issues with Linux and FreeBSD
  • Refinements to the new spectator UI
  • Further Red Alert balance adjustments

We hope this will be the last playtest build, and if no further issues are found we expect a new release version in a few weeks time. Head on over to our download page, try it out, and let us know if you find any issues or have any other feedback before it is too late! As always, the full changelog is available on GitHub if you would like to find out more.


Season 8 of the Red Alert Global League is well underway. Resident RAGL wrangler netnazgul has been posting weekly wrap-up reports on the forum (Week 1, Week 2), covering the highlights and providing links to stream VODs for everybody who would like to keep up with the action.

Explosive RAGL action
RAGL Season 8 has been packed with explosive action.

We have been relatively quiet about OpenRA’s Tiberian Sun mod lately, but this does not mean it has been abandoned. Development has been focused mainly on resolving low-level game engine issues, which has been slow due to the complexity of the work involved and relative lack of manpower.

Examples of this work can be seen in release-20180923 which included renderer changes that roughly doubled TS’s in-game performance, in release-20190314 which fixed a collection of game-breaking bugs with Nod’s cloak generator technology, and in the upcoming release which significantly improves deployable units and aircraft.

Deployable units were a big part of Tiberian Sun, with several combat units, support units, and even production facilities (in the Firestorm expansion) all having the ability to switch between mobile and stationary modes. OpenRA’s unit-deploy code was originally written for the classic Construction Yards, and was poorly suited for the more dynamic gameplay cases used in Tiberian Sun.

This code has been overhauled to add missing features and additional quality of life improvements. Deploy commands can now be queued between other orders (great for managing transports!), and deployed units can be ordered to undeploy and move to another location (including into a transport, or onto a service depot) as a single action. The risk of accidentally packing your Construction Yard with a misclick has been reduced by requiring the force-move hotkey to be held while issuing these orders.

Tiberian Sun update
Aircraft and deployable units work much better in the under-development Tiberian Sun mod.

The code defining aircraft and helicopter movement has also been rewritten, implementing many of the flight dynamics needed for Banshees, Orcas, and Carryalls. The Carryall’s transport behavior has also been refined, with unit pick-up behaving much like the original game, but unit unloading now requiring an explicit order like other transports. This makes it possible to queue multiple transport runs, or to land the Carryall without releasing its cargo. Carryalls can now also be ordered to pick up deployed units, which will undeploy for pickup once the Carryall arrives.

We are slowly working through our list of must-have features for a public release, but there are still many more to go. We still cannot predict a release date, but the Tiberian Sun mod is developed in the open on GitHub (like everything else in OpenRA) so everybody is welcome to follow the progress and participate in this work.
