About the game

Swarm MMO is a browser-based space strategy game with one resource and one gesture. Planets you own produce probes, and you drag probes at whatever you want to take. There is no build queue and no capacity limit: a planet can sit on a stockpile indefinitely, and nothing decays.

You spawn on a home planet surrounded by neutral ones, in a galaxy that also holds suns and a black hole at its core. Suns pay energy, energy pays for tech, and the black hole is the only win condition. Collapsing one destroys the whole galaxy, your own holdings included, and pays a permanent bonus in return.

Take the neutrals
Capture neutral or enemy planets to increase your territory
Hold a sun
Capture suns to collect energy and upgrade your technology
Collapse the galaxy
Collapse a black hole and destroy entire galaxies

Questions

Is Swarm MMO free?

Yes, and there is nothing to install. Credits are an optional currency for skins, colours and the Command Center panel; they never grant probes, production or combat strength, and meteorites and quests hand them out for free. See Credits & Cosmetics.

Do I need an account?

No. Press play and you spawn as a guest. Linking an email with a magic link keeps your progress across devices and is required before you can spend credits; credits earned as a guest follow you into the account you sign into.

What happens while I am offline?

Planets keep producing, automations keep firing, and other players keep attacking. Coming back to a smaller empire than you left is a normal outcome. See Automation.

How long does a galaxy last?

There are no rounds, and new galaxies spawn as the existing ones fill up. An individual galaxy does not last forever: its black hole eventually turns unstable and starts consuming its own garrison, and if that garrison runs out the galaxy collapses with nobody paid. Black Holes has the timeline. Prestige, energy, tech levels, credits and skins live on your account and survive every collapse.

Does it work on a phone?

Yes. It runs in any modern mobile browser, and dragging, box-select and the radial menus all work on a touchscreen. Adding it to your home screen installs it as a Progressive Web App.

Where do I learn the rest?

The wiki covers every mechanic with the actual numbers, and the Discord is where clans recruit.

Guides

The wiki documents every mechanic with the numbers the code uses. If you got here from another game, the genre pages compare them side by side.

Getting Started
Learn how to play Swarm MMO: spawn a home system, take neutral planets, and work toward collapsing a galaxy's black hole to win.
Planets
How planets work in Swarm MMO: probe production per minute, planet levels, upgrade costs, and why there is no capacity cap.
Meteorites
Meteorites are temporary bodies in Swarm MMO. Hold one for the hour it lasts and it pays 1 credit, one of three ways to earn credits without buying them.
Attacking & Capture
Combat in Swarm MMO: launch swarms, capture enemy and neutral planets, and use launch position to control swarm speed.
Bases
Bases are the only body you build in Swarm MMO. They run on super-probes, pay energy, belong to no galaxy, and survive a collapse.
Suns
Suns are energy-generating objectives in Swarm MMO. Capture them with super-probes, defend them, and relay reinforcements between them.
Black Holes
The black hole at a galaxy's core is Swarm MMO's endgame. Conquer every sun in the galaxy, stockpile megaprobes, then collapse it for permanent prestige.
Prestige
Prestige is permanent progression in Swarm MMO. Every galaxy your clan collapses adds 1 energy per minute to every sun you own, anywhere in the universe.
Energy & Tech
Energy is Swarm MMO's research currency, earned from suns. Spend it on nine tech upgrades that boost planets and swarms near a friendly sun or base.
Clans
Form or join a clan in Swarm MMO. Clan members are allies whose planets you reinforce instead of attack, and their suns both count toward a galaxy collapse and earn them prestige when it happens.
Strategy & Maps
Command many planets at once with multi-select, and read the strategic and logistics maps to spot threats and gaps in Swarm MMO.
Automation
Automate attacks, sun reinforcements, and upgrades in Swarm MMO so your empire keeps expanding and reinforcing while you are away.
Controls
Full list of Swarm MMO controls: mouse gestures, quick-send keys, box-select, automation shortcuts, touch gestures, and camera panning and zoom.
Logs & Notifications
The Logs panel records what happened to your planets, suns and black holes in Swarm MMO. Group your subscriptions, mute what you do not want, and turn on push notifications.
Credits & Cosmetics
Credits are Swarm MMO's optional premium currency for skins and recolors. Buy them, win them from meteorites and quests, or earn them by inviting players.
Command Center
The Command Center is a rented Swarm MMO panel that selects planets, suns, black holes and bases by condition and applies one action to every match.
