Periapsis: Gravity Slingshot

Periapsis: Gravity Slingshot is about leading humanity beyond the Solar System after Earth becomes unsustainable. You launch ships from fragile worlds, use gravity to chart routes through space, discover star systems and search for planets that could support civilization. Each expedition takes time and resources, and discoveries can reveal new routes.

Plan expeditions

Before each launch, you choose your cargo, destination and fuel use. You also decide when to scan planets, deploy equipment, trade or travel farther into the unknown. Preparation shapes each expedition.

Navigate by gravity

Time engine burns to reach escape velocity, then use planetary gravity to bend your trajectory and reduce fuel costs. You can scan planets for data and deploy probes from orbit to recover resources and rare samples.

Expand the frontier

Reveal star systems in the Star Atlas and travel through stargates to extend the frontier humanity can reach. Buy tools, unlock new ship hulls, seed promising planets and establish colonies beyond Earth.
