Ninja Master's: Haou Ninpou Chou, the sub-title loosely translated to "Scroll of the Supreme Ninja Arts", is a 2D historical-fantasy fighting game developed by ADK and published by SNK for arcades (running Neo Geo MVS hardware) on May 27, 1996.
The sixth and final fighting game developed by ADK, Ninja Master's takes place during the late era of feudal Japan, circa the 16th century Sengoku period, as players face off as one of 10 fictional ninjas. The game is known for allowing players to holster and arm their character's weapons at-will, allowing them to switch between different fighting styles. It also includes a universal chain combo system.
The game was released for the Neo Geo AES on June 28, 1996 and ported to the Neo Geo CD exclusively in Japan on September 27, 1996. It was later included in the 2008 Japan-only PlayStation 2 compilation ADK Tamashii, was digitally released for the Wii (as a Virtual Console title) in 2011-2013, and was digitally released as part of HAMSTER's Arcade Archives series on January 17, 2019 (for the Xbox One, PlayStation 4, and Nintendo Switch) and November 1, 2019 (for the PC).
