- Custom Faction Contest Results - 13 July 2026
The votes are in. Here are your winners:🥇 The Fleetmasters by Vinco 🥈 Lumenovis Enclave by Anoc tied with The Recyclers by ShadowTiger, Helios Dominion by fauxsoleil and Takarajin by AILYes, that's a four-way tie for second place. And yes, one of the fourth-place finishers is AIL from our dev team. AIL didn't want the key since they already have the game (and the source code) so we have sent out 4 keys in addition to the 3 keys for the voter raffle.What gets added to the game?The vote has nothing to do with which factions get implemented. The dev team will select the factions that fit the game best, and we'll contact those creators directly to work with them on the implementation. This starts after the summer holidays and will take months, not weeks, so don't expect them in the next update.DramaTying Steam keys to vote counts was a mistake on my part. Some people gamed the vote with s…

- Custom Factions - Free Content Update - 2 July 2026
Custom factions are here! Build your own faction from the ground up!You are no longer limited to the six premade factions. You can now customize the name, color, emblem, portrait, home planet and traits of your own faction. Most options are purely visual, but the home planet and traits can completely change how you play the game.There are 97 traits available to choose from, with up to 4 per faction and 2 trait points to spend, allowing huge number of possible faction builds. Some traits cost more than others, and negative traits like Astroprocessing Blindness hand you extra trait points in exchange for a drawback.Powerful traits like Precursors replace your explorers with the mighty Ancient ship. Reinforced Hulls make your ships convert all their shield hull points instead. Traits like Technological Geniuses decrease the cost of all techs by 2 gas, opening the door to a much heavier res…
- Custom Faction Portraits - 26 June 2026
Hello world! This is not Zeikko speaking! This is Pymous, and Zeikko forced me to write this article! Shame on him! 😆So hello, I am Pymous, a freelance artist. If you play Dominions or Shadow Empire, maybe you know me as a modder and map maker for my favorite 4X games.So why am I here? The upcoming Custom Factions update landing July 2 lets you build your own alien race when you start a game. Which, as it turns out, needs a lot of new alien faces.Zeikko and I have been in contact for a few months now (he even visited me in France! Thankfully before the current dramatic heat wave...), and a few days ago he shared a screenshot preview of his work on the Astro Protocol Custom Factions update. My first reaction was: damn, that's so cool, it's going to add so much replayability. And I immediately said, "I'm so tempted to paint some portraits for the new races!"Zeikko's response was instant:…
- Update 1.1.17 - 24 June 2026
Features Improve AI scouting, station building and ship target prioritization Prevent AI from clumping around planets
- Custom Factions - Major Update July 2 - 23 June 2026
After working day and night on Astro Protocol for over a year before the release and then the 1.1 update, I hit a wall. Classic post-release burnout. Rather than grind through it and ship something half-hearted, I stepped away and spent two months doing subcontracting work. This change of pace was exactly what I needed. Now I'm back, and 1.2 is the result.Custom FactionsThis is the feature I most wanted to build, and the one I think adds the most to the game.Until now you played the factions we designed. From 1.2 onward, you can design your own. Choose a portrait, logo, colors, ship graphics, home planet, and traits. There are tens of traits to choose from including already existing faction traits and research upgrades as well as completely new ones that change the game. You can also allow AI opponents to create and use custom factions against you for extra challenge and replayability.N…
