The villainous Mollusc sends Inky and Clyde to steal the Artifact — a magical power pellet protecting Pac-Land from evil — and then smashes it into four pieces, scattering them across time and space. Pac-Man must chase those fragments through prehistoric times, Ancient Egypt, the Middle Ages, and the Wild West before a malfunctioning Time Machine deposits him in one final era: the future. Only with all four pieces reunited can the Mollusc's destruction be undone.
