You are a phylum of life - mollusks, insects, vertebrates, or plant-fungus hybrids - starting at the invasion of the land 450 million years ago. Your goal is to dominate the planet, mutating your nervous, circulatory, digestive, or reproductive systems and speciating into flying, burrowing, swimming, and armored species.

This allows your species to become the apex carnivore or herbivore as the forests and swamps fill iwth tentacled squirrels, cud-chewing slugs, zombie flies, and other chimeras. Through an optional climate model of carbon, water, and oxygen cycles, as well as drifting continents, you battle the climate as well as other players. Maps for Venus or Mars are included, back when they still had oceans and possibly life.
