intro
I believe this is how it is played originally but I like to play it one octave up too 
(that means starting on the first fret of the e string).

rhythm guitar
Didn't feel like writing the rhythmic pattern, just play these 2 power chords how you 
feel they should go.

lead guitar
The lead guitar follows the vocal melody with a few slight differences in the end.

guitar solo
I don't know the exact guitar solo and I won't be trying to tab it out but I'll give you 
some tips about it. Rhythm guitar plays the verse.
      begins with       for 1st power chord  for 2nd power chord
e||--------------------|--------------------|--------------------|
B||-9-9-9-9-9-10--11---|-11--9------9--11---|--9--7----7--9------|
G||--------------------|--------10----------|--------8-----------|
D||--------------------|--------------------|--------------------|
A||--------------------|--------------------|--------------------|
E||--------------------|--------------------|--------------------|
Work around with those frets and for the last part just climb up the high tones of the 
first 3 strings (shouldn't be hard unless you're a newbie).

bridge 2
Same as bridge 1 but without the power chords. Starts before "Up in the sky" and plays 
through the whole pre-chorus. Use a flanger effect for this part.
e||--------------|
B||--------------|
G||--------------|
D||----------1---|
A||1-3-1-4-1---1-|
E||--------------|

pre-chorus
Starts after "And your doom will rain down!"
Play these power chords in the same rhythmic pattern as the verse. The last time don't 
play the 6-8-8 power chords.
E||------------------------------------|
B||------------------------------------|
G||------------------------------------|
D||-4-------6--------8-------8---------| x9001

ending
The same as the intro but without the last part

There are probably a lot of mistakes here so correct me if you notice them.
