About Main Sequence

Main Sequence - about the game
Command a small mining ship on the frontier of human-charted space to expand humanity's presence among the stars. Collect resources from a resource-rich asteroid belt using ship scanners and basic mining tools, then upgrade them to unlock automated drones for steady production. Build factories with machines linked by conveyor belts, optimizing production lines for efficiency. Design and expand ships and stations with a designer tool, saving creations to reuse or share. Navigate a procedurally-generated galaxy to uncover stellar phenomena, research vital technologies, and battle an awakened alien defense system with your fleet. Strategy and simulation fans who enjoy automation, base expansion, and defensive fleet combat will find a focused challenge here.

You have been sent out to the frontier of human-charted space in a small mining ship, tasked with expanding humanity's footprint amongst the stars. In order to succeed, you will need to collect resources, automate production, expand your base of operations, and research new technologies.

You start out alone in a resource-rich asteroid belt. Explore your environment using your ship's scanners to find the resources you will need to start building. Start out with the basic mining tools available on your ship, and upgrade them as your progress. Unlock automated mining drones to feed a steady supply of resources to your growing factories.

There's too much work to do yourself. Build machines, connect them with conveyor belts, and plan out your production lines in order to make sure everything is running at maximum efficiency.

Use the designer to build and expand your ships and stations. Unlock new modules as you progress, or build freely in creative mode. Save your designs to use again later, or to share with friends.

Explore a procedurally-generated galaxy, filled with allies and enemies alike. Use the technology you unlock to explore the far reaches of space and discover unique stellar phenomena like black holes and neutron stars. Each new area brings new challenges and rewards as you leave your mark on the galaxy.

Your industrial activity has awakened an ancient alien defence system. Use your fleet of ships to protect your base, taking advantage of their mobility to respond to threats. Or, take the fight to the enemy and destroy their defence platforms and shipyards.

Use the items you produce to research new technology. Prioritize the research that matters most to your survival and unlock new ships, station modules, items, and buffs to help you expand your base.
