About the Game
A side-scrolling beat 'em up where a resurrected centurion battles through five levels of mythological creatures. Players collect spirit balls to transform into powerful beasts including werewolves, werebears, weredragons, and werevigers, each with unique abilities. The game features a transformation system where collecting three spirit balls triggers a dramatic metamorphosis with increased strength and special attacks. Notable for its atmospheric Greek mythology setting and the iconic "Rise from your grave!" voice sample at the start.
