Around hour twenty the stars open up. Research the Space Elevator, build it, and your home world joins a four-planet trade network. Send a freighter to the Stellar Forge for stellar materials and the Type-1 Energy Matrix. Trade with Asteroid Belt Alpha for uranium ore and quantum crystals. Proxima Colony ships exotic biocarbons. Jupiter Station ships dense matter from the Jovian depths. The orbital ring below is real — click a planet to see its economy.
Each planet trades different goods. Build the right export and you can pull rare materials home that your factory could never produce on its own.
Your starting planet. Earth-analog atmosphere, 12 biomes, full procedural generation. Build your factory here — every interplanetary route originates from your Space Elevator.
An automated megaplatform anchored at the solar corona, operating at the edge of physics. It produces stellar-grade materials in exchange for advanced manufacturing components.
A network of automated mining stations in the asteroid belt. They produce rare minerals in exchange for fabricated components.
A fledgling human colony struggling to establish self-sufficiency. They need raw industrial materials and can offer exotic biocarbons.
A massive orbital platform harvesting Jovian atmospheric gases. They have access to exotic compounds found nowhere else in the system.
Build a Space Elevator and assign freighters to trade routes. Each freighter completes a full round-trip: depart loaded, arrive at the partner planet, unload, load their export, return.
Travel time varies by route — the Asteroid Belt and the outer colonies are quick runs, while the Stellar Forge at the solar corona is the long haul. Multiple freighters on the same route stagger automatically so you get continuous throughput.
Interplanetary trade unlocks at Tier 6 — once your home factory is humming, the system is your next playground.
