Step into the hauntingly nostalgic soundscape of the Absolute Class of '89 with the Kumitantei: Old-School Slaughter official soundtrack. This score perfectly captures the game’s "anemoic" atmosphere, blending the upbeat, synth-heavy vibes of 80s city pop with the chilling, dissonant undertones of analog horror.
