Press Kit

Kumitantei™: Old-School Slaughter is an episodic murder-mystery ADV cardbattler that lovingly fuses retro anime analog horror with killing game, coming to Steam Early Access in 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 '80s anime and classic Japanese mystery-adventure games, 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!
