The Anatomy of Metroid Fusion: Bad dreams (Patreon)

Man, thank goodness I'm playing Metroid Fusion on Virtual Console and can take advantage of save states. This is the third update in a row with a vicious, death-inducing battle to contend with. In fact, this one might be the worst of them all: The battle with Nightmare, probably the most difficult battle in all of the Metroid series... well, except perhaps for the final two bosses of Fusion. It's a great battle, though — it really puts you through your paces and uses nearly skill in Samus' arsenal.
