Ninja Gaiden Sigma guide

There's another door here - take that to reach the Middle Cabin. Break down all the wooden boxes here (but make sure to avoid the crates) and then look for a small crank you can turn. After turning it a bit, you'll be attacked by another wave of troops - but you know how to handle these guys by now, right? Right. Once you've handled that problem, return to the crank and resume the turning.

Now, you'll need to catch onto a line running across to the platform you see in the distance. Unfortunately, there are also soldiers on said platform that will attempt to shoot you as you're making your way over there. Take them out with a few arrow shots, then cross on over. (If you happen to run out of arrows, there's a box in the Middle Cabin that will give you a free refill.) There's another guardian waiting here for you - it goes without saying that you'll need to dispose of him. Grab the nearby treasure chest, then use your weapon to smash the very conspicuous broken window nearby. Jump through the broken window and make with the choppity to cut up the system's wiring and disable all the locks in the ship. Now you can finally reach the boss!

Backtrack all the way to where you first began (also, save your game) and enter the previously locked chamber that was near Hayabusa's room. Make sure you're ready first...
