The intro I think is just some palm muting, not sure but it's not that important. It 
immediately kicks off into the main riff of the song:

|-------------------------|
|-------------------------|
|-------------------------|
|-2-2-2-5-5-5-7-7-7-5-5-5-|
|-2-2-2-5-5-5-7-7-7-5-5-5-|
|-0-0-0-3-3-3-5-5-5-3-3-3-|

oh yeah and for part of the first verse guitar 2 one note ad nauseam:

|-----------------------------|
|-----------------------------|
|-12-12-12-12-12-12-12-etc...-|
|-----------------------------|
|-----------------------------|
|-----------------------------|

then this riff is for the first chorus:

|-----7-----7-----7-----7-|
|-------8-----8-----8-----|
|-9-9-----9-----9-----9---|
|-------------------------|
|-------------------------|
|-------------------------|

the rest of the song is just the main riff and there is a bridge between the second 
and third verse, but it's just:

|-----------------------------------|
|-----------------------------------|
|-----------------------------------|
|-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7---|
|-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7---|
|-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5---|
palm mute---------------------------|

guitar 2 plays this during the main bridge riff (over and over again):

|----------|
|----15----|
|-14----14-|
|----------|
|----------|
|----------|

and then it kicks back into the main riff...

and there you have it. good song, but easy to play.
