OVERVIEW
Kumitantei: Old-School Slaughter throws you into a gritty murder mystery, blending card battles and adventure with a heavy dose of retro anime horror. The game rolls out in episodes, so the suspense just keeps building. Every twist in the story feels loaded—sometimes, the smallest decision can flip everything upside down.
Picture this: it’s 1989, but not the Japan you know. Sixteen students wake up in an ancient, underground bunker. Nobody knows who pulled them there. The pressure’s on—they can either team up and dig up the truth or scrape by trying to survive. You’re right there with them, unraveling secrets, making tough choices, and shaping who makes it out and how the story wraps up.
