Alpha 1b is currently on Steam's "unstable" branch for testing. It's also available on Humble's "unstable" branch. This update fixes some important bugs and has a considerable amount of balance changes, for a better experience, especially on late game.

I invite everyone to opt for the unstable branch and test it out, if you don't mind to find a few bugs and imbalances in the way. There shouldn't be many bugs and the experience should be better, but still you're warned.

You can find the instructions on how to play this new "unstable" build here. On Steam you need to go to the Betas tab and set the unstable branch. To unlock the unstable branch just insert the password interstellarsg in the field: "Enter beta access code to unlock private betas". On Humble, you have two branches to choose to download the game from. Just choose the download from the "Unstable" branch.

Save compatibility: Savegames from Alpha 1a may work on Alpha 1b, however you will need to start new games to benefit from all the fixes and improvements of this new build. Therefore, we strongly advise that you start new games to play this build.

Once Alpha 1b is confirmed stable, we will release it to all users in the main branch. Hopefully within a day or two.

You can find the list of changes below.

Thanks a lot to everyone who has been providing feedback. Now please enjoy the new build and let us know what you think!

  • Fixed a major bug that was allowing the AI to equip more than one spinal mount modification on their Titan class ships. Only one spinal mount is allowed to be equipped in a Titan (note that only the Draguul and Moltar, or same affinity custom races, can equip a spinal mount on their Titans, for kinetic and beam weapons respectively. Soon, the other races will also have exclusive Titan powers.

  • Fixed an issue where pressing the ESC key in the main menu was causing the game menu to appear on top of the "New Game" UI screen.
  • Fixed an issue where the "New Game" UI Options tooltips had a gap (stopped being shown) between the text and the checkbox.
