Aimed at grown-up gamers who aren't easily spooked (but who like to be), Kuon is a horror adventure set in Japan toward the end of the Heian period (approximately 800 C.E. to 1200 C.E.). A castle in the capital of Kyoto is overrun with unholy zombie-like beings. Gamers can play as an exorcist named Doman, who goes to explore the strange happenings at the castle, or as Doman's daughter, Utuski, who enters the castle to look for her father. Completing the game with both characters opens up an additional, final chapter in the story, through which gamers play as a third, unlockable character.
