Symbio

Immerse yourself in a microscopic world teeming with life and multitudes of organisms, big and small, with each species trying to survive in the harsh environment of prehistoric Earth. A world that is undergoing constant evolution whether you are there or not. A world where size often matters and bigger cells often have an advantage over smaller ones (but not always, though). A cell-eat-cell world where each species becomes part of a larger food chain. From the simplest organism Prokaryotes to more complex Eukaryotes and Multicellular organisms, Symbio allows you to evolve beyond your current state. All you need to do is just survive. And if fail to do so, make sure you have enough progenies that will help propagate your species and continue your survival.
