Neo Zeed Marine Stronghold is the final stage from The Revenge of Shinobi.
Details[]
Having defeated all the ground forces of Neo Zeed, Joe Musashi makes his final assault on the group's marine fortress where Naoko is being held. The first takes place on the outside of the base, which is heavily guarded by soldiers and cannons. The second area is a very large and confusing maze, in which the player must use the doors in the background to traverse the area. The Ninja Master personally guards the captive Naoko at the end.
