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.
The first and smallest ecosystem of moss and rats was built on this planet.
It also produced some meat of rats, that is a good source of human nutrition.This could be a base of further terraforming and farming.The first minimal ecosystem of moss and rats was built on this planet.The moss is quickly eaten up, so all rats got died too soon.Rats can climb on slopes, but not on block steps.So it is clear that we have to make combination of slopes and blocksto prevent them from extinction.
