This 15-second music clip is a dark, driving boss battle theme with a haunting, ghostly edge, built around pulsing rhythm and eerie melodic lines that rise as the fight intensifies. It feels suspenseful, ominous and dramatic, like facing a powerful enemy that will not back down, and it gives any moment a sudden sense of danger and urgency.
