>_> Why wouldn't he be weak to plasma? Isn't that the idea, you've got the uber beam ahead of time and go in to whomp his ass with something you shouldn't have? I mean... fire melts ice...
Ice beam bounces off of him, Wave Beam is inherently weaker than Power Beam (which would just be normal damage)... am I missing something?

Oh and there are 3 remixed tunes (unless you count the whir of the elevator room as music):
-Tallon Overworld is a remix of the original Metroid Brinstar music.
-Magmoor Caverns is a remix of Super Metroid's Lower Norfair (Ridley's Lair) music.
-Lower Torvus is a remix of Lower Brinstar in Super Metroid.
