1. Amazing piece that not only fits the mood but hits you like a truck when you reach a certain spot in the game and just get filled with dread.
2. I found the zero gravity part pretty horrifying since you don't know where things are going to come from and sometimes have your oxygen depleted and this theme just adds to the panic.
3. I honestly want to put all of the dark themes from Metroid 2 on here, considering how each one is very disturbing as well as the Ing ones.
4. I'll never forget pressing that button and the words "Metroids have been released" displaying on the screen, nor will I forget how terrified I was to play that game in that one moment. This music just added to it all, let alone being themes for other creepy bosses.
5. Yeah, once you're discovered, this theme really shoots up as you are "literally" running for your life in that game.
6. The creepy atmosphere and boss fight was well complemented by this piece.
7. Just everything about this theme fills me with dread, especially in the context of the game.
8. Red sirens go off in my head whenever I hear this theme, and rightfully so.
