Combining 3D animation and 2D designs, the game follows the opera starlett, Mona, a woman kidnapped by Baron Shrowdy Von Kiefer and slowly becoming a creature of the night after coming under the vampire's spell. As she seeks to venture away from his gothic island-set castle, she'll have to learn to control her vampyric powers of turning into a bat, hypnotizing people, turning into vapor, and drinking blood from humans. Her friendly bat acquaintance, Froderick, will join her on her quest.
