You control a tribe of amoebas living in Earth´s past trying to survive in the Primordial Soup. At first¸ your amoebas drift along¸ eating the nutrients that are available¸ but soon you´ll have to figure out how to get to the rapidly depleting supply of nutrients before your opponent´s amoebas beat you to it. You will purchase rule-breaking Gene cards to give your amoeba capabilities to be the top dog in the Soup. Some of these capabilities include more coordinated movement¸ longevity¸ aggression¸ etc. The player who keeps his amoebas alive and balances the use of his or her Gene cards will reign in the Soup.
