Kumitantei: Old-School Slaughter Steam Digital Key

Is survival in the cards? Kumitantei™: Old-School Slaughter is an episodic murder-mystery ADV cardbattler that lovingly fuses retro anime analog horror with killing game! Kumitantei will consist of 6 episodes, beginning to release in early 2026. "The Empire of Japan, 1989... Awoken in a decaying old bunker, sixteen elite Absolute Students are trapped in a kill-or-be-killed Apathy Experiment.

Will they band together to uncover secrets of this anemoic alternate past, or lose their humanity and lives in the present?" With a visual style inspired by Rumiko Takahashi’s Urusei Yatsura and '80s anime alongside classic Japanese mystery-adventure games like Danganronpa and Ace Attorney, Kumitantei™ thrusts you into a suspenseful character-driven killing game narrative where your deckbuilding and detective skills are the only keys to surviving.

It's a creepy-cute love letter to decades of ADVs that wears its many inspirations on its sleeve: perfect for fans of visual novels, detective games, and deckbuilders with deep narratives.
