basically this is how you play the first riff in the song, the second riff is just about the same just more opens  in the begining. this  is the only change from the first time you play this riff till the last time you play, listen to it you will understand.

1.44 "IN THE COMPANY OF DEATH"  this can be tricky to figure out but it sounds exact, in my mind anyways. the first time one guitarist will play it then they both come in at the ending of the first riff
    :   :                     :  :                        :  :                       | this  is where the second guitarist would come in on.

2.34 "TO SEE THE STARS AGAIN"  this is now the outro you made it, listen to the song you will get the rythm down

B-0-0-0-0-0-0---0-0-0-0-0-0--| play this 12 times (one time = two 000000-000000) or play   0-0-0-0-0-0 26 times

 3.01  "FARWELL SKY, FARWELL SUN, FARWELL EARTH" on the 26th time there is a pinch harmonic and then its repeated.
