Periapsis: Gravity Slingshot

Earth is no longer sustainable.

Lead humanity’s final journey beyond the Solar System. Launch ships from fragile worlds, use gravity to bend your path, discover new star systems, and search for planets that could carry civilization forward.

Plan each launch, manage fuel and cargo space, and decide when to scan, deploy, trade, or push deeper into the unknown. Every expedition costs time and resources, and every discovery may open a new route for humanity.

Will you guide humanity to become a multi-planet species?

Key Features

• Skill-Based Launch & Gravity NavigationTime your engine burns, reach escape velocity, and use planetary gravity to bend trajectories and reduce fuel costs.
• Strategic Expedition PlanningChoose what to carry, where to fly, and when to spend fuel — preparation matters before every launch.
• Planet Scanning & Orbital DeploymentScan planets for data, then deploy probes from orbit to recover resources and rare samples.
• Star Atlas & Stargate ExplorationReveal new star systems, travel through stargates, and gradually expand humanity’s reachable frontier.
• Ships, Equipment & ColonizationBuy tools, unlock new hulls, seed promising planets, and establish colonies beyond Earth.
