Shien's Revenge is a 1994 rail shooter video game developed by Almanic Corporation and originally published by Dynamic Planning for the Super Nintendo Entertainment System in Japan and later in North America by Vic Tokai. In the game, players assume the role of the titular ninja to fight against monsters coming from a time portal in order to face against an entity known as Undertaker and rescue his companion Aska. Co-designed by Takashi Shichijo and mangaka Go Nagai, the title was created by most of the same team that worked on previous projects at Almanic such as E.V.O.: Search for Eden. It was met with mixed reception from critics since its release.
