Zerion: Infinite Space

Pilot the void. Stake your claim. The galaxy is open.

Zerion: Infinite Space is a free-to-play MMO set in an infinite procedural galaxy. Your starship, your sector, your rules — in a persistent universe shared with every other pilot on the server.

Infinite Procedural Galaxy

Every sector is generated on demand across an infinite grid. Warp deeper to find rarer resources, deadlier NPCs, and civilizations you've never seen. Nothing resets — your discoveries persist for everyone.

15 Playable Civilizations

From the disciplined Terran Commonwealth to the silicate Tharix Cabal to the time-weaving Chronos Seers. Each race ships with its own hull silhouette, faction palette, and lore. Choose your home, then trade or feud with the rest.

Real-Time Fleet PvP

Coordinate with friends, run garrison operations, and siege rival claims on a shared live server. Server-authoritative combat — every hit, every dodge, every warp is computed on the backend. No aim-bot survives a wing of human pilots.

Sector Claims & Sieges

Plant your flag on a sector you can defend. Take a cut of every shop transaction and run the local economy. Rivals can siege you back — earn what you keep.

52+ Weapons · 36+ Shields · 22+ Engines

Mix and match a build that fits your playstyle across 7 ship classes, from light Scouts to capital Motherships. Every loadout has counters; nothing is meta-locked forever.

Play Anywhere

Native Windows and macOS desktop builds via Steam. Also available in your browser at with no download, plus native iOS and Android apps. Cross-progression keeps your pilot identical across every device.

Free, Fair, and Yours

No pay-to-win combat upgrades — ever. Premium unlocks cosmetic ship patterns and quality-of-life perks only. Every gameplay edge has to be earned in-sector.
