Features
What waits out there.
One planet with nothing on it. A galaxy already in motion. Neighbours who got here first. This is what you can expect from AstroExpanse. The rest is yours to find.
01 / Your planet
It starts with one rock.
Mines, power, a shipyard, a lab: the classic loop on the original economy. Your colony is a 3D scene, and everything you build stands on its surface.
- 41 buildings, ships, defences and technologies, plus the Recycler, Lunar Base and Sensor Phalanx
- Queues finish on screen, with no refresh
- The Warden, your colony's machine mind, walks you through the first week with quests and rewards. You can dismiss it, though it has a lot to say
This planet has done nothing for four billion years. Let us end the streak.
02 / The galaxy
Every light is a place.
A spiral galaxy you fly through, from its arms down into a single system. Every star is a real kind of star: its class sets its colour, its size and how much your solar satellites yield around it.
- Dive from the galaxy into a system, and climb back out
- Red dwarfs, blue supergiants and everything between
- Prefer lists? The classic system table is one click away
At the centre there is something that gives off no light at all.
03 / Neighbours
You are not the first one here.
Six Houses of a fallen empire settle near new commanders while a universe is young. They are computer-controlled, always marked as a House, and they build, scout and keep a fleet like anyone else.
- They remember who raided them, and they answer
- Pirates strike from havens in black holes, only within their reach
- And other commanders: alliances, chat channels and private messages
A House sleeps at night. Mostly.
- Oran
- Vey
- Tessaly
- Durance
- Ilmarch
- Morrow
04 / Fleets
Send something. Watch it go.
Seven missions: attack, espionage, transport, deploy, colonise, harvest and reinforce. Pick a target on the star map, see who owns it, load the holds, and know the distance, timing and fuel before you launch.
- Probes bring back what is there
- Incoming fleets show up early; how much you see depends on your Espionage Technology
- Raids can fly out with cargo aboard, and every load takes dock time
Small, cheap and curious.
05 / Combat
It isn't over when they arrive.
A battle plays out over several minutes, in phases, and you can watch it in 3D. While it lasts, send reinforcements or pull your fleet out.
- Different ships dominate different phases. Which ones, you find out
- The simulator shows the range of likely outcomes before you commit
- Every fight is seeded and recorded on the server
Watch a live battle — no signup ↗They came, they shot, they left with less than they brought.
06 / Aftermath
What is left after.
Destroyed ships leave debris fields, and recyclers harvest them. A big enough battle can leave something bigger behind.
- Moons, and what a Sensor Phalanx can see from one
07 / The finale In development
Every universe has an ending.
Universes run in seasons. Late in one, the Abyss stirs, and alliances race to build a Gate at the black hole in the middle of the galaxy. How it ends, you will have to see.
08 / Fair play
Nothing for sale wins a fight.
AstroExpanse is free to play. Money buys cosmetics and conveniences, never power, resources or speed.
- New players are protected for their first week, or until they outgrow the beginner bracket
- Vacation mode that really freezes your empire
- In your browser, and on your phone too
- In English, Czech and Slovak
