Play as a primordial single celled organism in Earth's early oceans. Found a home colony, grow your forces, spec into the evolution tree and conquer your adversaries before the Great Oxygenation Event!
One living rival across the water, in lockstep. Create a match and share the code, or join a friend's.
Best iPhone-to-iPhone (same browser engine).
You are the colony. A billion hungry cells on the floor of a lightless sea. Claim the craters, rewrite your genome, and drown your rival before the rising oxygen drowns you both.
