Survive and colonize on an unknown planet near a red star. Find and gather resource, build shelter and engineering factory, avoid alien invasion, and finally build/maintain working ecosystem on the planet. Whole game goes within a single persistent simulator in the server that will be reset periodically with some game rule/setting changes. In short: massively multiplayer planetary colonization game.
Nothing is infinite on this game. The total amount of resources are constant.
The surface of this planet is not covered with water, but with vast amount of black carbonic powder dust.
The dust seems to contain some mineral, and slowly flows toward lower places.
I also put some amount of water on the surface, but it quickly vapored in open air.
To keep liquid water or moisture, we have to put it in underground chamber and block moisture goes out.
