A tight and tactical turn-based 4X strategy game where every move counts. Explore the galaxy, colonize new worlds, research powerful technologies, and command deadly fleets to lead your empire to victory.
Astro Protocol is a cosmic simulation program overseen by six rival galactic factions. On this platform, the fate of the galaxy gets determined by every battle, anomaly, and advancement.
Explore a unique hex-based galaxy map
Each map offers a new procedurally generated layout — and a new challenge. Explore bright stars, dangerous asteroid fields, resource-rich gas giants, habitable planets, and mysterious anomalies.
Discover anomalies and unlock powerful rewards
Anomalies are events where everything can happen. Each anomaly is AI-free and features hand-crafted art by the talented artist Sami Rouhiainen. Choose from powerful, game-changing rewards that shape each run in a different way.
Colonize and terraform planets to expand your empire
Some planets are ready for colonization, while others must be terraformed to support new forms of life. Establishing colonies expands your supply network, lowering energy upkeep costs and enabling deeper exploration. The more colonies you control, the more resources you’ll generate to fuel your growth across the stars.
Build space stations and ships to control the stars
Build space stations to harvest nearby resources from gas giants, stars, and asteroid fields. Use those resources to build ships with unique roles — from agile scouts to long-range carriers and heavily armored battleships. Shape your fleet to fit your strategy and gain control over your rivals.
Research new technologies to gain the upper hand
Mix and match technologies from three unique tech branches, each offering powerful upgrades that shape your strategy. With randomized technology options and limited research capabilities, no two runs are the same — making every decision matter.
Crush enemy fleets
Every ship has two attack stats: the number of strikes per round and the damage dealt by each strike. Whether your enemy is heavily shielded or armored will determine the tactics you’ll need to use. Shields regenerate each turn, but armor is permanent — choose your attacks carefully to exploit enemy weaknesses.
Race for victory points against rival factions
Gain victory points by controlling planets and stations and by discovering anomalies.
The first player to reach the required victory points wins!
Were excited to announce that Astro Protocol will be part of Next Fest, October 1320!
To celebrate, were releasing Update 0.15bringing major improvements to the demo including the Myrmidon Horde, a brand new playable faction available only during the festival week.
New Faction: The Myrmidon Horde
The Myrmidon Horde joins the battle for control of the Protocol. This faction is composed of species bound by swarm intelligence and divided into specialized sub-classes. Many slaves from other alliances have been absorbed into the swarm or adapted its parasitic survival strategies on their own. Under a rigid collective will, Myrmidons have been reshaped for different roles across the cosmos.
Fatal experiments have accelerated their evolution, giving them high mobility at the cost of shorter lifespans. Despite their isolationist nature, Myrmidon galactic politics remain fiercely expansionist.

New Ship Classes
Every ship in Astro Protocol now belongs to one of four core classes, giving fleets clearer roles and tactical depth.
Scout class ships are weak and inexpensive.
[/*]Cruiser class ships are fast, offensive ships with high attack and damage values.
[/*]Battleship class ships are slow, defensive ships with high armor and shield values.
[/*]Carrier class ships are long-range ships with strong support abilities.
[/*]
Weve also added 19 new class-specific technologies and upgrades. Researching these allows you to specialize your fleets, from stronger Battleship armor to faster Cruisers or improved Carrier strike range. We\'ve also renamed and rebalanced some of the ships.
This new structure gives fleets clearer roles and new possibilities for customizing your strategy.
New Anomalies
The Protocol has become even stranger. You will now encounter new anomalies that offer powerful rewards and upgrades for specific ship classes. Choose your upgrades wisely and adapt your fleets to each challenge.

Other Updates
We have also made a lot of other updates since 0.14.0 such as adding a new station, Network Hub which can be used to extend network, made many improvements to user interface, tutorial and enemy AI. In fact the AI improvement Xilmi has been making has made the normal difficulty AI so good that I have lost against it on two developer streams on a row now.
Join the Festival
Version 0.15 includes all the content planned for the demo. Next, our focus will shift toward developing new features and content exclusive to the full version of the game.
If you have not tried the demo yet, now is the perfect time. It is feature complete, and the Myrmidon Horde faction will be available only during Steam Next Fest. Next Festwould also be a great time to let your friends know about the game and ask them to wishlist or play the demo.
We will also be hosting a live developer stream at the start of the festival, showcasing Myrmidon Horde gameplay. The stream will be available on our [u]https://store.steampowered.com/app/3727420/Astro_Protocol/\"" style="color:#bb86fc;text-decoration:none;">Steam page [/u]. Will I lose against the AI for the third time in a row?
