What is Main Sequence?

You're at the frontier of charted space in a small mining ship, expanding humanity's footprint among the stars:

• Mine and refine: scan asteroid belts for the best spots, then refine resources on your ship.
• Build stations and factories: place machines, connect them with conveyor belts and plan production lines, then set up automated supply routes between stations.
• Design every ship and station inside and out, module by module: cargo, reactors and weapons. Save designs, share them or build freely in creative mode.
• Fight back: your industry wakes an ancient alien defense network, so you'll need a fleet and, eventually, the ultimate battleship.
• Research and explore procedurally generated star systems with wrecks, new resources, black holes and neutron stars.
