1 4 update beta 800 450

Hello everyone!

We're very excited to announce that the next major free update! for ISG is now available for public testing on Steam's unstable Beta branch!

Please note that 1.4 unstable is an optional beta update. If you want to help test it alongside us you have to manually opt in to get access. In your Steam library, right click on Interstellar Space: Genesis -> Properties -> Betas tab -> Select the "unstable - Unstable Beta Branch for Testing" branch. The game will update and you'll be able to start playing with the new additions and improvements.

For GOG, in GOG Galaxy choose the ISG game card, then Options -> Manage Installation -> Configure -> Beta channels -> Select 'Add private channel' -> Insert password: betatesting and then select the "unstable" beta channel, which will be available from the channels dropdown. The game will update and you'll be able to start playing with the new additions and improvements. To return to the version of the game currently in production you just need to revert to 'Disabled' beta channel on GOG or 'None' in the betas tab on Steam.

1.4 highlights include 3 new leader skills (Surveillance, Metalworker and Curator), revamped strike craft 3D models (fighters and bombers), leader level information now presented in the various leader screens. There's also AI improvements, a ton of QoL improvements and tweaks, bug fixes, and much more.

We will be monitoring your reports for major bugs in the next few weeks and fixing them. Please report them in our Steam forums, GOG forums, official forums, on our Discord server, or if you prefer just send an email to (or contact form here) with a save and the Player and Player-prev log files you can find in this folder: C:\Users\<your_username>\AppData\LocalLow\Praxis Games\ISG

Compatibility note: Saves from previous versions are not compatible with 1.4 beta.

That's it for now. Hope you enjoy the new update. Let us know if you find any issues. Thanks everyone for reading and for the support!
