The game follows Avenging Spirit , a spirit seeking revenge after being murdered by gangsters who have taken his girlfriend hostage. His father uses a machine to bring him back, demanding that the gang hand over research on ghost energy in exchange for her safe return.
Players control the vengeful spirit as he navigates six stages: city streets, rooftops, a factory, sewer tunnels, and the gangsters' base of operation. The twist is that the player can possess 20 enemies, using their skills and weapons to aid in completing levels. However, each time the player leaves an enemy's body, their own ghost energy decreases.
