PlotNeo Zeed is threatening the world once more. The evil crime syndicate - thought to have been vanquished two years earlier - has returned, headed by a man known only as the Shadow Master. Joe Musashi has felt their presence, and descends from the lonely mountaintops of Japan to face his arch-nemesis once more. As the Shinobi, stronger than steel and faster than a whirlwind, the last keeper of the Oboro Ninjitsu techniques, only he can stop Neo Zeed.
- Round 1: Zeed's Resurrection: Joe Musashi descends from his training grounds in the mountains after he learns that the syndicate Neo-Zeed has emerged with a vengeance from the criminal underworld; he battles waves of assassins and faces Guard Lobster; a huge mutated samurai through the forests and caves of Japan.
- Round 2: Secret Entry: Musashi races on horseback through the meadows as a storm gathers and Neo-Zeed's assassins descend from kites to attempt their kills, including a ferociously agile ninja in orange with a large supply of spears — Kage the Jonin. The conspiracy is revealed to be much larger and dangerous than expected as Musashi reaches a huge high-tech facility, neutralizing Neo-Zeed's machine gun-armed soldiers and encountering a levitating robot armed with bullets, bombs, lasers, and reality-warping trickery — the first brain-powered jet-piloting supercomputer's successor.
- Round 3: Body Weapon: The facility houses a morbid biological weapons laboratory, where Musashi must fight off mutated brains and muscular ooze, descending into the sewers where he faces off against one of Neo-Zeed's most horrible weapons: the hulking and hideous Hydra.
- Round 4: Destruction: Musashi discover a great river near his home, where Neo-Zeed has constructed a huge factory between this river specializing in robotic weaponry. He surfs across the river fighting off hordes of Neo-Zeed's Ninjas, who are riding on huge, hovering futuristic vehicles. On the river, he confronts humanoid robots armed to the teeth with lasers and machine guns.
- Round 5: Electric Demon: Upon crossing the river, Musashi arrives at another heavily guarded weapons facility in the forest. It is as if he has descended into hell, as he fights the military guerrillas amidst a burning inferno that has engulfed the forest. Seeking justice and shelter in the facility, Musashi ascends into the top floors and confronts Mechasaurus; a hulking, fire-breathing, robotic dinosaur who resembles Mechagodzilla (perhaps as an allusion to the Godzilla battle in The Revenge of Shinobi), one working prototype of a planned army of these beasts.
- Round 6: Traps: Musashi descends into a gorge, fighting to stay alive by killing bloodthirsty assassins and seeking a little safety while falling down toward a great canyon. After fighting Karura; a mystical humanoid hawk, Musashi discover the lair of Neo-Zeed's last echelon: a mist-shrouded pagoda. He avoids several lethal traps and twisting passages to meet the Zeed Lieutenant Byakushishi.
- Round 7: The Final Confrontation: Despite defeating Byakushishi in a violent battle, there is one final nail to pound into the coffin of Neo-Zeed. Musashi ascends into the sky on Neo-Zeed's massive air fortress where his most formidable enemy awaits his arrival: Zeed's true leader, the Shadow Master; a villainous shinobi whose fighting abilities are equal to Musashi's, and his weapons wield unprecedented power.
Gameplay is similiar to that seen in The Revenge of Shinobi, in which Musashi must complete multiple stages, defeat enemies, and destroy bosses. His main weapons are throwing shurikens, Ninjutsu magic (both in limited supply) and various melee attacks. In addition, Musashi can now wall jump, climb across ceilings and pipes, and dash across the ground for a powerful sword slice. In two stages, Musashi also rides on a horse and a surfboard in auto-scrolling stages where he must shoot out incoming enemies.
