Game Overview
Kumitantei™: Old-School Slaughter is an episodic murder-mystery adventure card battler that masterfully combines retro anime analog horror with a high-stakes killing game. Set in the Empire of Japan, 1989, sixteen elite Absolute Students awaken trapped in a decaying bunker, forced into a brutal kill-or-be-killed Apathy Experiment. Players must decide whether to unite and unravel the dark secrets of this anemoic alternate past or succumb to the deadly present. Featuring a visual style inspired by Rumiko Takahashi’s Urusei Yatsura and classic ‘80s anime, alongside influences from renowned mystery-adventure games like Danganronpa and Ace Attorney, Kumitantei™ delivers a suspenseful, character-driven narrative where deckbuilding and detective instincts are essential to survival. This creepy-cute homage to decades of adventure games invites fans of visual novels, detective stories, and deckbuilders to immerse themselves in a rich, atmospheric experience. In Kumitantei™, players bond with the Absolute Class of ’89 by listening to their stories, exchanging gifts, and acquiring powerful cards to use during intense debates. The game challenges you to investigate grisly murders, meticulously examining crime scenes and gathering evidence to present in trials where deception and truth clash. Inspired by the courtroom mechanics of Ace Attorney and the high tension of Danganronpa’s trials, each Clinical Trial ends in bloodshed, forcing players to think critically and act decisively. Build your deck by combining cards found in the bunker and earned through social interactions to dominate debates and courtroom battles. Additionally, the game features retro-inspired mini-games that pay tribute to classic arcade icons, testing your nostalgic gaming skills. Kumitantei™: Old-School Slaughter offers a unique blend of mystery, strategy, and dark storytelling that keeps players on edge until the final verdict.
