Planet Sim

Your colony ship, the Ark, broke apart in orbit. You land on a procedurally generated planet with a rover, a lander and a plan. The planet is filled with savannas, rainforests, deserts, glaciers and volcanoes, rivers and seas, and day and night, and every seed makes a new one. Build a factory colony across it, launch the parts back up, and rebuild the Ark.

Biomes, rivers, ore deposits and landmarks land somewhere new on every seed, so no two starts play the same. Pick a preset or set the world rules yourself, from a relaxed sandbox to a tougher run.

Drones harvest, haulers drive the roads between Logistics Hubs, and freight trains, ships and cargo planes link your far-off outposts. Route everything through hubs, or link buildings directly.

Build a Launch Pad and Mission Control, put stations in orbit and set up an outpost on the Moon. Keep it supplied, and send cargo up with a mass driver.

Colonists come down from the Ark in pods. They need homes and food from your farms, fisheries and kitchens, and many buildings won't run without a crew.

Hold your base with walls, turrets and shields, or train squads and take the fight to enemy camps. Native fauna, the Reclaimers and the Skarn each fight differently.

The long goal. Every system you build feeds it: factories make the parts, rockets carry them up, and the Ark comes back together piece by piece.
