The Nightmares Beginning

I'm going to first give credit to those who helped me tab this and ofc Nobuo Eumatsu for
it.
#1: SilvaGunner on Youtube for posting this "video"
This helped me play it by ear accurately the way it is played in-game.
#2: SouthSaturn on Youtube for posting this Video
This helped me play it not only visually but also opened up more complex variations and
alternatives to the riffs.
Since this entire song is played via chord progressions I will also post a chord graph
each part.
NOTE: An x on the fretboard of chord graphs = a note change. In this song, for instance,
indicates the pinkey fingers change to the third fret(on the e-string) in the main riff.
Main Riff
     E_a_d_g_b_e
     _ _ O _ _ _
     | | | | | O
     | | | O O |
     | | | | | x
     | | | | | |

     E_a_d_g_b_e
     _ _ O _ _ _
     | | | | O O
     | | | O | |
     | | | | | x

     E_a_d_g_b_e
     _ _ O _ O _
     | | | | | O
     | | | O | |
     | | | | | x
     | | | | | |

This next part is difficult to coordinate. There is an easier alternative to this part,
I don't think it sounds as good. This alternative is second.

Alternative

The main riff repeats again but instead of using the last riff you play this chord.
     E_a_d_g_b_e
     _ _ _ _ O O

     | | | O | |

Riff 2
      E_a_d_g_b_e
      _ _ _ _ _ _
 3rd  | | | | O |
      | | O | | |
      | | | | | |
      | | | O | |
This first chord is really a ***** to get used to at first.

     E_a_d_g_b_e
     _ _ _ _ _ _
     | | | | | |
     | | | | O |
     | | | | | |
     | | O O | |

     E_a_d_g_b_e
     _ _ _ _ _ _
     | | | | | |
     | | | | O |
     | | | O | |
     | | O | | |

Then it goes back to...

Riff 3
Here is where I get an ere****n lmao jk
I would suggest playing the following chord with your index ring and middle because
need your pinkey to do changes on the e-String. (Although make the second note change with
index).
         E_a_d_g_b_e
         _ _ _ _ _ _
   5th   | | | | | O
         | | | | | x
         | | O O | |
         | | | | | x

      E_a_d_g_b_e
      _ _ _ _ _ _
      | | | | | |
      | | | | | |
      | | | O O O
      | | | | | |
(I suggest barring this chord)

This next one is a bit of a stretch for your pinkey but whew does it sound beautiful.
      E_a_d_g_b_e
      _ _ _ _ _ _
      | | | | | |
      | | | | O |
      | | | O | O
      | | | | | |
      | | | | | x
      | | | | | x

      E_a_d_g_b_e
      _ _ _ _ _ _
      | | | | | O
      | | | O | |
      | | | | O |
      | | | | | |

This next part is definitely the hardest. Not only is this chord a ***** to place, but
also requires a good pinkey stretch at the same time.
