Getsu Fūma Den

Getsu Fūma Den is a 1987 action role-playing game developed and published by Konami for the Famicom exclusively in Japan. It has been referenced in many subsequent Konami titles throughout the years. The game is structurally similar to Castlevania II: Simon's Quest, The Goonies II and Teenage Mutant Ninja Turtles (NES). A hack-and-slash "roguevania" sequel, titled Getsu Fūma Den: Undying Moon, was released on the Nintendo Switch on February 9, 2022 and left Early Access on Steam on February 17. Another sequel titled Shin Getsu Fūma Den was planned for the PlayStation 2, but was cancelled.
