Moonstone: A Hard Days Knight, is a video game developed and published by Mindscape in 1991. It was released on the Amiga and one year later converted to MS-DOS with alternate sound and music. The title is a play on A Hard Day's Night. Moonstone's gameplay blends several different genres, including strategy, real time fighting and role-playing video games. It allows up to four players to participate in a basic turn based Role Playing Game with real time combat for any encounters. It is also notable as one of the goriest games of its time, with some exceptionally bloody fight and death scenes.
