Open field noteMultiplayer
03The current multiplayer picture, what each captain can own, what remains unconfirmed, and a planner for splitting the workload.
Open field noteMain Sequence is a first-person space-sim factory builder from solo developer Tumbling Dumpling Studio. Start with one mining ship; end with an interstellar industrial network.
You scan and mine asteroids, refine ore aboard your ship, then build a station and move production indoors. Machines, belts, power and storage turn manual work into a factory. Research turns that output into new ships, modules and sectors.
The calm loop has teeth: industrial activity wakes an ancient alien defense network, so your fleet is both a hauling network and a response force.

This is the confirmed gameplay spine described by the developer and storefront. The exact recipe ratios belong in-game or in a future database pass.
Use ship scanners to identify worthwhile asteroids in the starting belt.
Mine by hand from the ship, or scale up with mining drone bays on a station.
Process ore on the ship early, then move refining and crafting into station machines.
Power the station, connect machines with belts and solve material flow.
Feed produced items into science to unlock logistics, production, power and ship technology.
Build a fleet, move between sectors, defend the network and push toward the next science tier.
Selected verified changes to the game and demo. The full, dated timeline is in the update log; we do not invent patch cadence.

Release
Tumbling Dumpling Studio confirmed the Steam Early Access date. Price and launch-time details were promised for a later announcement.

Small, functional tools with a clear job. They run in your browser and do not require an account.
TOOL 01
An estimated unlock countdown and local-time converter, with the official and unofficial parts labelled separately.
TOOL 02
A spoiler-light progress list from first scan to Slipstream Drive. Saved in your browser, not on our server.
TOOL 03
Split logistics, production, defense and exploration across two to four captains before your first session.
We are deliberately not inventing a full item encyclopedia before launch. The database covers what official material and the demo actually show.
Ores, refined goods, components, science types
Production, power, logistics, defense and hull systems

Main Sequence is still in development. That makes precision more valuable, not less. Official statements, storefront data, community-tested demo findings and unconfirmed details are marked separately across every guide and database page.
Official storefront
The free demo is live on Steam. The full game enters Early Access on November 12, 2026. Price and exact unlock time remain unannounced.
