Ninja Gaiden is a side-scrolling, hack & slash, platform-action video game developed by SIMS and released by Sega for the Master System in 1992, with license from Tecmo.
This video game stars Ryu Hayabusa and is part of the Ninja Gaiden series, although it features a plot not connected to any of the other Ninja Gaiden games. Due to the discontinued support of the console in Japan and North America because of its bad sales, the game was only released in Europe, Australia and other PAL territories, bearing the Ninja Gaiden label instead of the Shadow Warriors one that was usually used for the series by the time in PAL releases.
