The tab that was on here just didn't seem right so I changed it a bit.
Tabbed by Dobby

Play when drums kick in

Intro/Verse (Play softly then slowly louder)
G|—————|
D|—————|
A|3—5—0|  Repeat until vocals then play at regular volume
E|—————|

When it slows down, play
G|————|
D|————|
A|3~——|   Then go back to verse when the guitars start
E|————|

Then play the intro part (softly then louder)
The Prechorus is the same as the verse but i
  like to play the sustained third fret note while mixing it up a bit
The chorus you play the verse but i like to play this:
G|————————————|  |————————————|
D|————————————|  |————————————|
A|7—00—7—00—7~|x2|5—00—5—00—5~|x2 while mixing up the ends
