The Ninja

The Ninja (忍者), a port of the arcade game Sega Ninja, was released in 1986 in Japan and 1987 elsewhere by Sega. It is a typical 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.

Among the changes from the arcade version are the female protagonist being changed to a male ninja called Kazamaru. 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.
