At the start of each mission, the player is shown their objective, followed by a file containing a photograph of the enemy boss and a map display pinpointing the location of the next stage. Through five missions (consisting of three stages for the first mission and four stages each for the rest), Musashi must make his way to Zeed's headquarters and free all the hostages in the first two or three stages before confronting the boss at the final stage of each mission.
The player controls a ninja named Joe Musashi who has to stop a criminal organization called 'Zeed' who are kidnapping the children of his ninja clan. In Shinobi, the player controls a modern day ninja named Joe Musashi who goes on a mission to rescue his kidnapped students from a group of terrorists.
