You wake in a sealed birth cluster. One world, a dormant beacon, and no other commander who can find you — because you are not broadcasting yet.
Build a system. Survive what is already out there. Then decide, on your own schedule, whether to switch on the thing that puts you on everyone else's map.
The first few hours
Not a tutorial you skip. This is the game — and none of it requires another player to show up.
01
Your birth cluster is sealed. No raids from established empires, no alliance politics, no one scanning you for weakness — you have not announced yourself, so there is nothing to find.
Sealed is not the same as safe. The dark is already occupied, and the first thing that comes for you is local.
02
Not a scatter of identical colonies. One hub — a full world that holds the system's stores — and chartered annexes around it: a mining rig on a moon, a sensor post out at the rim, a shipyard on a rock nobody could live on.
They share one economy automatically. The hub commutes workers out and pushes power across the grid, so a world too harsh for a city is still a perfectly good mine.
03
A pirate hulk is already sitting in your home system, and it will raid you before you are ready for it. Beat its shields down, board it, and it is yours — a mobile deep-space base you did not build and could not have afforded.
Every battle is fought at range. Weapons that cannot reach the distance you are fighting at contribute nothing, which is why a mixed fleet beats a bigger uniform one.
04
The Cold Fusion Beacon is the door to everything social: trade, diplomacy, guilds, the shared galaxy. It is also the moment you become findable.
That is a real decision and the game treats it as one. Quiet holdings grow slowly and safely. Lit ones grow faster and get visitors. Nobody makes it for you.
Where this goes
Four concentric rings, sealed from each other by dark-matter barriers left over from the catastrophe that nearly ended everyone. You start on the outermost and poorest.
Constellations are shapes you learn to recognise — The Forge, The Spiral, The Claw — and you drill from the whole galaxy down to a single moon in one continuous zoom.
Inner rings are richer, and they are sealed for a reason. The walls come down on the galaxy's schedule, not yours, and when one falls it opens for everybody at once.
See it fight
Not a trailer and not a mock-up. This engagement was fought by the game engine, recorded tick by tick, and replays in 3D in your browser — no account, nothing to install.
The attacker won and lost six ships doing it. Both fleets spend the opening closing distance, because nothing can fire until the range band allows it — which is the whole argument this game makes about combat.
The actual game
Not concept art. A real colony in a real system, rendered by the game you would be playing.
What's actually different
Fleets close over real range bands. Missiles reach, energy melts shields, point defense eats both. Range, not stack size, is the first question.
Battles leave debris and disabled hulls. Bring a Reclaimer or the winner of the salvage race is whoever did.
Anything substantial moves in real freighters over real distance, and can be intercepted on the way. There is no teleporting market.
A hub and its annexes are one economy with one attention chip. Your empire scales in systems, not in things that individually nag you.
Schematics are found, studied and reverse-engineered from what you capture — not unlocked from a flat tech list.
No beacon means no market and no allies — and no presence on anyone's scan. Some commanders never switch it on.
The yard
Capitals do not slingshot and do not warp — they tear their own passage through subspace and burn antimatter doing it. Getting one anywhere is a plan, not a reaction.

ColossusRingbound is in open alpha and the population is small. You will meet rough edges, and you will meet the developer — reports on Discord go straight to the person who can fix them.
Your progress is not wiped. There is no cash shop, nothing to buy, and no advantage for logging in more often: builds, research and fleets all run on the server whether your tab is open or not.
Free, in your browser, no download. Five minutes to start and no rush after that.
