Description

You start on Earth with a launch pad and a government contract. Build a satellite, scan the Moon, buy a Sparrow capsule, crew it, load structural panels, tool kits and oxygen, and land. On the Moon you raise an Outpost, fill its tanks and put astronauts and workers to work: foot patrols, radar sweeps, rover surveys, research runs. Contracts from the Agency, daily orders for every world you have opened, side jobs and achievements pay along the way.

Then Mars — the same rules, its own look, its own resources and four times the ground. Research is a ladder: unlock rocket families, then push each one tier by tier until even your first Sparrow can reach Mars. The 3D map is the whole solar system, every planet and famous moon with real facts; worlds not in the game yet say when they are coming.

Everything keeps running while the app is closed. The Agency's director issues and closes every contract in her own voice; the company's onboard AI walks you through the first days.

What makes it different

  • Made without a computer: a phone, a terminal over SSH, and cloud builds — every screenshot reviewed on the same phone it was tested on.
  • A voiced Agency and company AI that never talk over each other.
  • Honest monetization for a sim: premium currency buys time or supplies, never progress; every spend shows exactly what it buys before you confirm.
