Compile Heart is working on Mary Skelter Finale, which will follow the act of Mary Skelter: Nightmares, Mary Skelter 2, and the various short stories and spinoffs when it comes to PS4 and Switch.
Mary Skelter fans can look forward to a similar system in Finale, with the addition of new features like a Zapping System that lets players swap in real time between various protagonists.
The Mary Skelter series of dungeon-crawling RPGs is preparing for its grand conclusion.
