Description

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.

Features:

  • Bond with your classmates! Get to know the Absolute Class of '89 by listening to them, giving them gifts, and receiving powerful cards to use during debates!
  • Investigate grisly murders! Use your detective skills to comb through slain classmates’ crime scenes and take your evidence to trial!
  • Survive the trial! Cut through the lies and prove your case. Inspired by Ace Attorney and the cult classic Danganronpa series, 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 debates and trials!
  • Please insert coin! Test your retro gaming skills in a variety of faithfully crafted anemoic riffs on true old-school arcade icons!
