Codex Gamicus

SEGA Ninja (known as Ninja Princess (忍者プリンセス) in Japan) is a 1985 arcade game released by SEGA. The game features a female ninja who must battle enemy ninjas using throwing knives and throwing stars.[2]


Gameplay is typical of a run and gun game, such as Commando, where the player has to shoot enemies and defeat a boss.

Enemies include samurai, enemy ninja and dogs. The player's normal weapons are an unlimited supply of throwing knives, but power-ups to throwing stars are available. In addition, the player can also turn invisible for a short period of time. While most of the stages are vertically scrolling, a few of the levels add some variety - including a level where the player must scale a wall.[2]

Home Versions[]

Ports of the game were released for SEGA's SG-1000 and Master System consoles.

The latter version, retitled "The Ninja", was released a year after the arcade game and changed the protagonist from female to male. Other changes include the rearranging of stages from the original Japanese release in western releases of the game as well as a scroll system, which requires that five green scrolls must be collected to get to final level of the game, as all of them give hints on how the final level must be entered. If the player finishes the game without them, the game will backtrack to a level closest to where a missing scroll lies.[3]
