Known as The Super Shinobi II in Japan, Shinobi III is regarded by many as the high point of the series. It introduced a much smoother, faster style of gameplay while keeping the series' familiar trademarks firmly intact. The game marked Musashi's last appearance in a Shinobi game until Shinobi was released in 2002 for the PlayStation 2. At least two known beta versions of Shinobi III are currently in circulation, featuring almost completely different levels from the final game.
