Dr. Rockman.EXE Operate Shooting Star is a remake of the first MegaMan Battle Network game that includes characters from the MegaMan Star Force series. MegaMan.EXE is a doctor and has to operate the Shooting Star MegaMan to save him.
Actually, no it's not. This game doesn't exist. It never even began development. Apparently on this website all you need to have a "fan game" is a title and a summary of it's concept.
