Shinobi III: Round 4: Destruction (Hard)

Joe Musashi has discovered another factory from Neo Zeed, this one focusing creating robotic weapons. He decides to shut it down by surfing towards it. SURFING NINJAS! WOO! This plays out like Round 2 Act 1's horseback ride where Joe instead surfs as the game automatically progresses on its own. Like before, he can still divekick during this state. Watch out for enemies that lay mines here, and also look out for slopes you can jump off of for some big jumps. The first boss is a mech that can shoot scatter shots, mines, and block your shuriken with its shield. Destroy this thing to get to Act 2. Act 2 is a normal stages, where Joe must travel over and under a lot of pipes. There are two opportunities to get 1-UPs here, and you have to make sure not to fall too deep into the water. The last boss of this Round is a bigger mech. It has a variety of attacks that it will use on you. What you have to do is take out each of these weapons before you can truly destroy it for good. This is easier said than done, of course, especially if you lack/lose your POW shuriken during the fight.
