Kumitantei: Old-School Slaughter downloadable game

Kumitantei: Old-School Slaughter is a downloadable PC adventure game published by Akupara Games and developed by Mango Factory. It releases on April 23, 2026, and activates via a Steam account. The title blends retro anime aesthetics with a killing-game narrative across six planned episodes.

Players who want a story-driven card-battler mystery

This game suits players who enjoy episodic murder mysteries, deckbuilding mechanics, and visual novel presentation inspired by classic Japanese adventure titles. It is not for buyers seeking multiplayer modes, open-world exploration, or fast-paced action combat without narrative focus.

Six episodes with detective and deckbuilding depth

The experience delivers six episodes of investigation, trial sequences, and strategic card battles set in an alternate 1989 setting. Spoken English and subtitles in English, Japanese, Simplified Chinese, and Spanish - Spain provide broad language support. Players who require offline play without Steam DRM should look elsewhere.
