Ninja Gaiden 3: Razor's Edge | LOA Chairman Fight (Hard Difficulty)

The second and third phase of this boss fight were borderline controlling-throwing levels of frustration. The phases aren't hard but fighting the camera and the invisible walls and boundaries led to some cheap deaths. Hard mode is general is a mess and I'm somewhat of a masochist with playing games on the hardest difficulty the first playthrough.

You definitely want to reserve and use your level up health unlocks for this fight in case you are having issues beating the boss. This fight was harder than the final boss IMO.
