What is Main Sequence?
Main Sequence is a first-person space factory simulator developed by Tumbling Dumpling Studio and published by Mythwright. You start with a small mining ship, gather resources from asteroids, and build stations that turn basic materials into an automated industrial network.
Its core systems combine conveyor-based production, technology research, modular spaceship construction, logistics, and alien combat. You can explore alone or in co-op, with a free Steam demo available ahead of the planned Early Access launch.

01
Main Sequence Beginner Guide
Start with a mining ship and learn the opening loop of scanning asteroids, collecting ore, and refining basic resources. Follow the path to your first space station and automated production line.
1
Use the starter mining ship's scanners to locate resource-rich asteroids in the opening belt.
2
Mine nearby deposits and refine collected resources aboard your ship.
3
Build a space station to establish a permanent base of operations.
4
Install production machines and begin researching technologies that unlock further automation.
02
Main Sequence Automation Guide
Build your first factory with machines and conveyor belts, then connect material flow to storage and assembly. Learn how to troubleshoot missing power and move from a single station to larger production networks.
1
Place production machines on your station and plan the input and output flow.
2
Connect machines with conveyor belts so resources can move through the production line.
3
Supply power and the required materials to keep refineries, assemblers, and research machines running.
4
Expand logistics across stations and use transport ships to move supplies between them.
03
Main Sequence Research Guide
Understand the technology tree and the material-based science system used to unlock new equipment. Covers common research bottlenecks, including Solar Panels and the Electromagnetic Science introduced in the updated demo.
1
Produce the specific items required by the technology you want to research.
2
Deliver the required resources to the appropriate science labs, including via conveyor-fed production.
3
Read the inputs for the selected technology and check that each required science line is receiving material.
4
Explore Electromagnetic Science, added to the demo in the October 19, 2026 update.
04
Main Sequence Mining Guide
Learn how asteroid scanning, shipboard refining, and mining drone bays support early resource production. Expand from manual ore collection to mining outposts that feed your automated factory network.
1
Scan the starting asteroid belt for accessible mineral deposits.
2
Mine raw resources with your ship and process them using its refinery.
3
Establish a station near useful deposits and add a mining drone bay as progression allows.
4
Connect mined materials to storage and production, then use cargo ships to supply other stations.
05
Main Sequence Shipbuilding Guide
Design functional spacecraft by combining modular ship components with cargo, propulsion, and defensive equipment. Explore the building choices that matter for hauling resources, exploring sectors, and protecting your stations.
Modules
Design ships module by module, balancing the layout for your intended role.
Cargo
Plan cargo capacity and reactor placement alongside other functional modules.
Weapons
Equip weapons for threats posed by the alien defense network.
Shields
The October demo update introduced the Shield Generator Mk. 1 as an additional ship-design option.
06
Main Sequence Logistics Guide
Connect distant stations with transport ships, docks, drone bays, and automation schedules. This module focuses on recurring player questions about loading, unloading, and making autopilot routes work reliably.
Drones
Mining drone bays collect resources around stations, creating a need for well-placed outposts.
Docks
Dock conveyor connections move goods between station production lines and docked ships.
Autopilot
Give transport ships an ordered schedule to move supplies between stations.
Wait Rules
Test one load and unload cycle before using cargo counts as autopilot conditions.
07
Main Sequence Warp Drive Guide
Follow the progression from local space travel and the Slipstream Drive toward advanced interstellar exploration. Distinguish October demo content from broader playtest progression, including distant resources and the Relic Destroyer encounter.
Slipstream
Slipstream Drive research precedes the expansion into more distant sectors described in the official playtest roadmap.
Resources
Cobalt and Graphite in other solar-system sectors support Electromagnetic and Quantum Science progression.
Relic
The official playtest progression identifies the Relic Destroyer as a prerequisite for Interstellar Warp Drive research.
Star Systems
Interstellar Warp Drive opens travel to other systems containing resources for Astronomic and Xenobiologic Science.
08
