Get into Early Access:  Steam  |  Epic

Additional Custom Civ Portrait Options

Users can now select "More Images" until they get the image they want (based on the description of your civ).

Previously, to get more potential race images to choose from, you had to regenerate the entire civilization. Because of how taxing that is on the AlientGPT system, we had to limit that to 5 tries per civ and 25 per day. But since most people just want to try out to see more images, we are separating the civ regeneration to the reroll of the images.


More Civs Unlocked

Players can now play as the classic GalCiv civs, the main GalCiv III civs and the the new GalCiv IV civs. The new Supernova civs are still locked for now as we are still working on them.


New Settings

We are starting to tweak the civ traits and will be working on these throughout early access to make all of them more interesting.

New Default Strategic Zoom Settings

If you found the iconizing agonizing (I’ll show myself out) then you’re in for a treat. We’ve rebalanced when and how different icons show up as you zoom out.

AI to Supernova

Beta 1 of Supernova was focused on AlienGPT and making sure it didn’t blow up on your computers. It mostly didn’t. Beta 1A brings the new AI over. Which isn’t to say the AI in Beta 1 didn’t work, it just hadn’t been updated yet to support all the changes to Supernova yet. You will find it much more engaging.

Updated Visuals

We’ve done our first pass on the visual style of the map itself. Gone is the blah grays. Also, you can set it so that you can see which tiles have been explored.


More Sophisticated Diplomacy

The computer players have a lot more nuance now in how they deal with each other. There are a lot more things that can happen in GalCiv IV: Supernova that affect relations. Sometimes you’ll have to pick who are your friends and who are not and live with that. It also means the other civilizations will be more likely to have diplomatic challenges with each other as well.


Major Balance Pass

Everything from how the galaxy gets generated to how much a pulse cannon costs has been looked at and adjusted. We’ve also brought back a lot of starbase upgrades that were previously only available to the Synthetic civs (By popular demand).

This list will be too big to cover here but it’s a big set of changes. We’ve been reading every forum post and every Discord talk.

Bug Squashing

From typos to crashes, we’ve been squashing bugs to get this update ready for you guys. We’ve even brought in a veteran game industry editor to finally deal with the typos.
