Good conversion of Sega's arcade version of Shinobi and maybe the best home version. One of the five arcade levels is missing, but playability, graphics and music are good - much better than Ninja Warriors for example. Shinobi plays also quite different from other Ninja games, because you do not punch, kick or kill your enemies with a blade, but only use shuriken as weapon. This makes Shinobi more a shooting game, but in a typical beat'em up level setting.
