Dyson Sphere Program Build a factory across an entire galaxy

You land as a space engineer with almost nothing and build upward from mining machines and coal power. Belts carry ore to smelters, smelters feed assemblers, and those products unlock better tech, faster transport, and travel to new planets. Each planet has its own minerals, day-night cycle, and orbit, and each new starmap is randomly generated. You place a logistics tower on a distant mining world, ships start ferrying its resources home, and your starter base quietly becomes an interstellar supply chain.

This is the city-planning part, minus the traffic complaints. Buildings snap to the grid, belts auto-align, and blueprints let you save a working factory block and stamp it down elsewhere. You go from a tangled starter line to deliberate districts of smelting, research, and power, tuned for stable output. The end goal is literal: gather enough energy and materials to build Dyson Shells on multiple orbits around a star, connecting nodes into your own pattern. It is zoning, but the neighborhood is a solar system.

Growth attracts attention. The Dark Fog sends attacks against your factories and your mech, called Icarus, and the busier you get, the harder it pushes. You answer with defensive structures, and you can customize Icarus with colors and components for exploring neutron stars, white dwarfs, red giants, and black holes. The combat is tower defense next to your spreadsheets: keep the lines running, keep the shields powered, and keep building while something tries to chew on the power grid.
