Main Sequence is a first-person space simulation that combines factory building, spaceship design, and large-scale automation.

Build an Interstellar Industrial Empire
What begins with a modest mining vessel can eventually grow into a massive industrial empire spread across the galaxy. Build spacecraft at Main Sequence, establish space stations, and create automated production networks as humanity pushes deeper into uncharted space.

The journey starts at the edge of known human territory, where a small mining ship is sent to help expand humanity’s presence among the stars. Progress depends on gathering valuable resources, developing production systems, researching advanced technology, and establishing new bases throughout the galaxy.
Mining, Manufacturing, and Automation
Early on, a resource-rich asteroid belt provides everything needed to get started. Scanners help locate promising mining spots, while the ship’s onboard equipment handles the initial processing in Main Sequence. As operations grow, a dedicated space station becomes the next step, providing a permanent home for expanding industrial facilities.
Factories quickly become the backbone of the entire operation. Set up different machines, link them with conveyor belts, and organize production lines to keep materials moving without unnecessary delays. Once the basic systems are in place, automation can reach far beyond a single station. Establish supply connections between distant outposts and let a dedicated fleet handle deliveries, freeing up time to focus on bigger projects.
Design Ships, Defend Your Territory
Building spacecraft and stations isn’t limited to choosing from a collection of ready-made designs. Every structure can be customized from the inside out, with individual modules determining its layout and capabilities. Decide where cargo storage goes, position reactors, and equip weapons according to the needs of each mission.
Finished designs can be saved for future use or shared with friends. For those who prefer unrestricted building, creative mode offers the freedom to experiment with different constructions at Main Sequence.
There is also a reason to think carefully about defensive capabilities. Expanding industrial activity eventually attracts the attention of an ancient alien defence network, which considers humanity a threat. Protecting stations and supply lines becomes increasingly important. Build a capable fleet to defend established territory, or take the fight directly to the enemy before another wave of attackers arrives.
Research, Exploration, and Cooperative Play
Resources aren’t just useful for manufacturing. The products created across the industrial network also fuel technological research at Main Sequence. New discoveries unlock additional spacecraft, station components, equipment, and upgrades, giving access to more advanced construction possibilities.
Expanding into unfamiliar regions brings fresh opportunities, but it also introduces new dangers. Each frontier presents different obstacles, resources, and hostile forces to deal with. A powerful battleship can make a major difference when facing tougher enemies, so developing military technology is just as important as improving production.

Features of Main Sequence:
- Exploration takes place across procedurally generated star systems, each presenting its own logistical problems and discoveries. Abandoned wrecks may contain useful finds, while previously unknown resources offer new opportunities for expansion. Space also has its share of extraordinary sights, including black holes and neutron stars.
- The experience can be enjoyed alone or with friends in co-op mode in Main Sequence. Every participant commands their own ship, making it possible to split duties between mining, logistics, exploration, and defence. Alternatively, everyone can work together toward the same goal. Having more players means more room for ambitious projects and an even larger interstellar operation.
