Planet S

Planet S is a real-time strategy game where your goal is to colonize multiple planets in a solar system to advance your civilization, build a city and supply it to grow your faction.

The world consists of up to 16 procedurally generated planets which you can colonize. A planets type affects things like the appearance, the farm productivity and the kind of resources you can find on it. Every player starts the game with a spaceship and enough materials to colonize their first planet. Uncolonized planets can be claimed by building a spaceport on it. Once you claimed a planet, you can integrate it into your economy!
