In Shootanto: Evolutionary Mayhem, players start as primates and battle lizardmen across the epochs, from primeval to medieval times and beyond. Players who survive each battle will evolve from a lowly monkey to an apeman, then caveman, a human knight, and finally a soldier. The combat continues to change as the lizardmen also evolve throughout the game.
