Main Sequence

Main Sequence is a space game about expanding humanity’s presence in frontier space. Starting with a single mining ship in a resource-rich asteroid belt, you gather and refine resources, build and expand a space station, automate production and research new technologies. You can play solo or in co-op, where each player captains their own ship.

Build your operation

Use scanners to find promising mining sites and refine resources aboard your ship. Establish a space station as a permanent base, then expand it with factories. Build machines and connect them with conveyor belts to create production lines, and automate supply routes between stations so your fleet can keep them provisioned.

Design ships and stations

Design every ship and station module by module, inside and out. Choose cargo capacity, reactor placement and weapons to suit the situation. You can save designs for reuse, share them with friends or build freely in creative mode.

Research and defend

Use the items you produce to research technology. Each unlock adds ships, station modules, items or upgrades, helping you expand into new frontiers, where new challenges and enemies await. Your industrial activity awakens an ancient alien defence network that identifies you as a threat. Protect your operation with your fleet or attack the network before the next wave arrives, and build a battleship to face the threats in your path.

Explore star systems

Each procedurally generated star system brings its own logistical challenges. Explore wrecks, find resources and discover stellar phenomena such as black holes and neutron stars.

Co-op

In co-op, each player captains their own ship. Players can divide responsibilities, with some handling logistics, defence or exploration, or work side by side on the same objective.
