Ninja Princess

Ninja Princess known as Sega Ninja in the west, is a Sega System 1 arcade game by Sega. It is a top-down shooter/action game, in which you play as a princess disguised as a ninja who is attempting to stop the evil tyrant Gyokuro. The game was ported to the SG-1000 in 1986 exclusively for Japan, with an MSX port following shortly afterwards. It was also brought to the Sega Master System as The Ninja, however The Ninja makes several adjustments to the story and characters, as well as updating the gameplay. Unlike the original arcade machine, the SG-1000 and MSX ports contain only 13 levels instead of 16.
