The stars are calling — and your industrial empire starts with one small ship. Main Sequence, the highly anticipated first-person space-sim factory builder from Tumbling Dumpling Studio and publisher Mythwright, blasts into Steam Early Access today, 12 November 2026. It’s time to leave your mark on the galaxy — one conveyor belt, one refinery, one star system at a time.
FROM ASTEROIDS TO INTERSTELLAR INDUSTRY
You begin alone at the edge of known space, aboard a humble mining ship adrift in a resource-rich asteroid belt. There’s no grand empire waiting for you — just raw rock and the quiet hum of your engines. Your mission is simple in concept, vast in scope:
Mine resources ? refine materials ? build factories ? automate production ? expand across star systems ? defend your legacy
What starts as manual mining quickly evolves into sprawling space stations connected by automated supply routes. Design every module of your ships and stations — inside and out — then save your blueprints and share them with the galaxy.
FACTORY BUILDING — BUT WITH A COSMIC TWIST
Main Sequence blends the satisfying flow of games like Factorio and Satisfactory with immersive first-person exploration and deep-space logistics:
- Build anywhere — Construct stations in orbit, on asteroid surfaces, or drifting in deep space
- Full automation — Conveyor belts, refineries, and automated supply fleets keep your economy humming while you explore
- Design your fleet — Every ship is custom-built. Cargo capacity, reactors, engines, weaponry — you decide module by module
- CO-OP CAMPAIGN — Team up online or over LAN, each player captaining their own vessel. Divide roles: one manages logistics, another explores, a third patrols the trade routes. The bigger your crew, the grander your ambitions
- DEFEND YOUR OPERATIONS — Your industrial growth hasn’t gone unnoticed. An ancient alien defence network has woken up — and it’s targeting your expansion. Build weapons, patrol fleets, and defensive platforms to protect what’s yours
- EXPLORE PROCEDURAL STAR SYSTEMS — Black holes, neutron stars, derelict stations, and rare resources await in every new sector

THE TECHMASH TAKE
Factory simulators meet space exploration — it’s a dream combination that feels obvious yet surprisingly rare. Main Sequence nails the core appeal: that hypnotic rhythm of watching a well-oiled production line do its work, then strapping on your thrusters and soaring out to claim the next system. The first-person perspective makes every station feel like a place you actually inhabit, not just a blueprint on a screen.
Co-op changes everything too — running a shared logistics network across multiple star systems with friends opens up possibilities that simply aren’t there solo. Whether you’re a solo industrialist or part of a four-strong orbital corporation, there’s a universe here waiting for you to build it up — and protect it.
Main Sequence is available right now on Steam. Grab your pickaxe, fire up your thrusters — the void is calling, and it’s time to get to work.
