Celestium

Explore the Celestium, a realm full of treasure and treachery alike. Starting with nothing but the clothes on your back, you must craft tools, collect food, and build shelter to survive. Extract resources, develop technology, and build spacecraft to embark on your cosmic adventure. But beware, the Celestium is old and vast, and for every precious ore vein or habitable world you find, there are a great many dangers lurking, waiting for the opportunity to attack.

Celestium is a procedurally generated open world survival game set in space. Its galaxy is comprised of thousands of systems, each one with its own real time Newtonian physics simulation.
