The game Mary Skelter Finale, developed by Compile Heart and published by Idea Factory, has officially announced that it will be released on Steam this fall. The Steam version will feature everything from the previously launched versions on Playstation 4 and Nintendo Switch, as well as downloadable content and the romantic visual novel Mary Skelter: Locked Up in Love - True End.

The Mary Skelter trilogy is a collaborative project between Compile Heart, Dengeki Bunko, and Dengeki Playstation, which debuted in 2016, offering players an RPG game that blends puzzle-solving, horror, and dynamic 3D dungeon exploration. In Mary Skelter Finale, the series' ultimate chapter, protagonists from the previous games will team up to tackle all the puzzles, and players will have the ability to freely switch between these characters.

Mary Skelter Finale is set within the Jail - a living prison for humans, buried 666 meters underground. It appeared suddenly several decades ago, giving birth to monsters called Marchen and patrolled by madness-inducing Nightmares. A group of prisoners, Jack and the Blood Maidens, were reincarnations of fairy tales who dared to escape. They climbed from the bottom of the tower up to the surface, filled with hope...

But outside were thousands of corpses soaking in a sea of blood. There stood beings known as Massacre Pink, smiling. In that moment, hope was destroyed. The group was torn asunder, with Jack and the Blood Maidens scattered to their own paths. Separated, they are each drawn to the devouring Jail that floats in the sky... This is the finale to the tale of the Blood Maidens.
