Pac Man World 3 (PS2)

An evil genius named Erwin has created a device that opens up a gateway into the world of Pac-Man's eternal enemies: the Ghosts. This machine is now causing the Spectral Realm to spill over into the real world, threatening all who live there. Who better to stop this haunting menace than the old Ghost muncher himself? Somehow, Pac-Man is mysteriously transported out of Pac-Village into the danger zone to stop Erwin. In an interesting twist, Pac-Man will be receiving some help from a most unexpected source -- his former ghostly enemies, Pinky and Clyde.
