About This Game

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, coming to Steam Early Access in 2025!

"The Empire of Japan, 1986... 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!

Features:

  • Bond during Free Time! Get to know your classmates by listening to them, giving them gifts, and receive unique powerful cards to use during a Card Battle Debate!

  • Investigate grisly crime scenes! Use your detective skills to comb through murdered classmates’ crime scenes and take your evidence to trial!

  • Survive the Clinical Trial! Cut through lies and deception with a War of Words and one-on-one Card Battle Debates to uncover the truth! These high stakes, high energy Clinical Trials can only end in bloodshed, whether it's the culprit's or everyone else's!

  • Build your deck! Create absolute combos using cards you find in the Bunker and through bonding with your classmates to dominate the Clinical Trials!
