ASTEROID DOMINION
A free multiplayer space game that runs 24/7 right in your browser. Pick a faction, mine drifting asteroids, build a base, and fight for the top of the galaxy. No download, no lobbies, and your progress never resets.
What is Asteroid Dominion?
Asteroid Dominion is a browser-based multiplayer space game with no download and no install — just sign in and fly into a galaxy that runs around the clock. There are no matches and no lobbies. When you arrive, hundreds of asteroids are drifting under gravity, AI ships are patrolling faction territory, and other players are mining, fighting, and building all at once.
Everything you earn sticks. Your ship level, your claimed asteroids, your turrets, and your standing on the leaderboard all carry between sessions, because this world is never wiped or season-reset. Choose a faction, upgrade your ship across eight stat categories, and decide whether you want to trade, fight, build an empire, or go rogue and answer to no one.
It is built by Sandbox Studios LLC, an independent studio shipping near-daily updates — "Where your game is never over."
Why you'll keep flying
One galaxy, endless ways to play it
Persistent 24/7 World
Jump into a living galaxy that never stops and never resets. Your level, your turrets, and your territory are all still there when you come back.
Four Factions, Four Playstyles
Side with the law, the traders, or the swarm — or go solo as an Outlaw. Each faction's signature harpoon ability rewrites how you fight.
Mine, Refuel, Get Rich
Strip asteroids for materials and fuel in the same beam. Mining isn't downtime — it's how you keep your shields up and your hold full.
Build & Hold Territory
Claim asteroids and mount turrets that defend your space around the clock — they keep firing even while you're logged off.
Real-Time Combat
Dogfight players and AI with bullets, harpoons, and physics-driven ramming. Hunt the rotating bounty target for double XP.
Smart Autopilot
Set your ship to mine, patrol, defend, or build itself while you plan your next move. Every enemy runs the same brain — learn it and outplay it.
How to play
From never-played to flying in about a minute
Sign in with Google
One click, no install. Your progress saves automatically to your account.
Pick a faction
Concordium, Unbound, Bone Collectors, or Outlaws — each one plays differently.
Fly with four engines
Q E thrust forward, A D reverse; steer by thrusting one side harder. On touch, twin sliders or a one-thumb joystick.
Mine your first asteroid
Switch to the mining laser with W, hold fire on a rock, and fill up on fuel and materials.
Fight and survive
Keep fuel in the tank so your shields stay up, and back off when a big hit forces a shield reboot.
Build and climb
Claim a rock, mount a turret, and chase the daily leaderboards. Read the full first-session walkthrough.
Choose your side
Four factions, four ways to fight — pick fresh every time you spawn
Concordium
Coordinated patrols who ARREST intruders — their harpoon locks an enemy's engine and weapons for seven seconds while the squad closes in.
Unbound
The economic faction. Their LOOT harpoon siphons enemy cargo while they mine, claim, and fortify the richest asteroids in the galaxy.
Bone Collectors
Sheer numbers. Their AI swarm outnumbers everyone roughly five to one and their EAT harpoon gnaws health straight through shields.
Outlaws
No teammates, no rules, the highest XP per kill in the galaxy — and everyone is a target, including you.
Master the galaxy
Deep-dive guides for every system in the game
Combat
Three weapons share one slot, so every fight is about committing to the right tool. Master the fuel-to-shield loop and the rotating gold-ring bounty and you'll win fights you used to lose.
Read the combat guideMining & Economy
Everything you build starts with a rock. Eleven asteroid tiers pay out materials and fuel at once — bigger rocks are richer but far more dangerous to ram or shatter.
Read the mining guideBuilding & Claiming
Turn materials into something nobody can loot: claim an asteroid for your faction and mount turrets that hold the line while you're away. Cluster on chokepoints to fortify a sector.
Read the building guideGalaxy Events
The galaxy never holds still. Gravity shifts through four phases, the Bonefall whips the swarm into a frenzy every quarter hour, and the bounty reshuffles constantly. Read the rhythm.
Read the events guideLeveling & Stats
Spend level-ups across eight stats to build a tank, a glass cannon, a mining rig, or a turret architect. There's no single right loadout — and your progress survives death.
Read the leveling guideAI & Autopilot
Pick where to fly and what to do, and your ship handles the rest — mining, patrolling, defending, or hunting. Every enemy runs the same brain, so reading it is a real edge.
Read the autopilot guideControls
A four-engine flight model means steering emerges from thrust, not a turn key — odd for a minute, instinctive after a session. Full keyboard, mouse, and touch, all competitive.
Read the controls guideDaily Highscores
Three daily contests reset at midnight UTC — most valuable kill, biggest single life, and longest survival — plus an all-time board that never resets. Champions are named each morning.
