ISG_expansion_3_dev_diary_26_800x450.png

Hello everyone,

Today we want to share an important update about the future of ISG, and more specifically about the long-awaited third expansion.

Expansion III is coming in 2026

After many months of dedicated work developing and refining this massive new chapter of ISG, we’re excited to announce that Expansion III is planned for release in 2026.

Development is progressing steadily, and this expansion is shaping up to be exactly what we envisioned it to be. We’re also building upon everything we’ve learned from both your feedback and our own evolving design goals.

While we’re not ready to announce a specific release date yet, we can say with confidence that the expansion will be out in 2026, unless something very unexpected prevents it...

ISG_1_6_4_update_800_450.png

Hello everyone!

It’s been a few months since we released the free 1.6.3 update. We hope you are enjoying that update with its new features and improvements.

In the meantime, we’ve been listening to your feedback, so here’s a smaller patch that adds some improvements and a few bug fixes.

This update is available in all stores. On Steam it will auto-update. On GOG it will also auto-update on GOG Galaxy. If you don’t use GOG Galaxy, you’ll need to download the offline installers for the new version in your GOG account. The new DRM-free version is also available on Humble Bundle (*) and Itchi.io (check for the latest version 1.6.4 on those stores).

Note (*): It may take a day or two to be available on Humble Bundle.

ISG Dev Diary #24: Game status – Next free update and Expansion 3

Hello everyone.

It’s been a while since we last reached out and I thought this would be a good time to provide an update on the ongoing activities and on what you can expect for Interstellar Space: Genesis going forward.

First, I’d like to thank everyone who has bought the game, and the expansions, so far. That is key so that we can continue providing support and producing new content for ISG.

Secondly, I’d like to share that development activities were delayed this past year due to family business issues that needed my utmost attention. Progress was made on new art procurement for expansion 3, but the new features’ development (coding) stalled to a halt for a few months and was reduced for the rest of the year.

That said, I’m happy to report that my family issues are now resolved and I’m ...

ISG Dev Diary #23: Update 1.6.2 and Terrains Pack

ISG_dev_diary_23_update_1_6_2_and_TerrainsPack_final.jpg

Hello everyone!

Hope you’re enjoying your time playing ISG with the latest version (1.6, now 1.6.1) released this past November. In the meantime, we’ve been working on the next update, the third expansion pack, and a new piece of content that was still unannounced, called Terrains Pack, to be released later today.

Free Update 1.6.2

One thing we’ve been hearing in player feedback for a while now is that the game could have more terrains, so colonies would look different when you build a few of them in the same biome type. Adding new 3D terrains is not trivial and can be quite time-consuming. However, we thought it was time to add something extra in the next update.

Therefore, included in the 1.6...

Let’s explore some of the major changes of 1.6 Beta, and later on you can check out the details of the update and on how you can try it for your self and offer your feedback to the Devs!

This was a highly popular feature request by the community, and something we really wanted to offer at some point, and it finally makes it in for 1.6!

In addition to the existing Election and Alliance victory conditions, and the traditional winner conquers all way to win (now called Conquest Victory), you now have the following new ways to win: Wonder, Domination, Science, and Score victory conditions! Here’s a brief break...
