“A free open-source game for PC and Linux about evolution, in which the player guides a species from their origin as a microbe to the space age and beyond. Gameplay is split into seven stages – Microbe, Multicellular, Aware, Awakening, Society, Industrial and Space. Through each of these you will guide your creature towards intelligence, sentience and the stars. Our team seeks to accomplish two major goals: create engaging, compelling gameplay that respects our players’ intelligence, and remain as accurate as possible in our depiction of known scientific theory.”
