Intro
I usually play this an octave higher when i play it. start on the 20th fret and work 
like that.

G-8888888888888-8888875-7777753-5555531-1111100---|
D-------------------------------------------------|
A-------------------------------------------------|
E-------------------------------------------------|

Rest of song
For the majority of the song just play this

G--------------------------------------|
D---------------------(11 not 1)-------|
A-33333333-66666666-11111111-8888888---|
E--------------------------------------|

Drum fill
When it goes into that drum fill i usually play

G--55-55-5-|
D----------|
A-3--3--3--|  X4 (i think)
E----------|

Another way of playing the song is to have the E string tuned to drop C and play 2 
at once

G--------------------------------------|
D--------------------------------------|
A-33333333-66666666-11111111-88888888--|
C-00000000-33333333-88888888-55555555--|

Gives it more of a kick like that. i also use a distortion pedal on this song aswell.
Cheers
