Hmm, I've just worked out how to play this song, and realised there was no perfect tab. 
I thought I'd have a go at making one. (This is my first time. ^_^)

Please refer to the song to get all of the timings right. (There's a load of complex 
which would be tedious and difficult to type up.)

Tuning: Half-Step Down. (Although I'll refer to standard tuning throughout this song.)

INTRO:        <--------------Main Riff------------------| (x2)
e|-10----|x-x|------------------------------------------|
B|-10----|x-x|------------------------------------------|
G|-0-----|x-x|------------------------------------------|
D|-7-----|x-x|------------------------------------------|
A|-8-----|x-x|-3-(x8)--5-(x3)--7-(x5)--10-(x8)--3-(x8---|
E|-------|x-x|-1-(x8)--3-(x3)--5-(x5)--8--(x8)--1-(x8---|

<-------Main Lick--------| (During the second time of the Riff)
e|-----5-3--|-----5-3----|
B|---------0|------------|
G|-2h5------|-2h5-----2--|
D|----------|------------|
A|----------|------------|
E|----------|------------|

There are two seperate guitar parts (one plays Riff and the other Lick,) but if you were 
play this on your own I suggest playing one Riff and one Lick.

VERSE 1 (part 1): Lasts two Main Riff lengths. Played as silent, but I suggest playing 
heavily palm-muted if practicing alone to get the timing right.

VERSE 1 (part 2)*:

VERSE 2 (part 1): As with Verse 1 Part 1, palm mute main riff chords. (They seem more 
in this verse than the first verse.)

A|-3-(x8)--5-(x3)--7-(x5)--10-(x8)--3-(x8)|
E|-1-(x8)--3-(x3)--5-(x5)--8--(x8)--1-(x8)|

(then there's an odd chord change after a one bar rest:)

e|-----------------------------------------------|
B|-----------------------------------------------|
G|-----------------------------------------------|
D|-5-(x6)--4-(x2)--2-(x6)------------------------|
A|-3-(x6)--2-(x2)--0-(x6)--5-(x2)--3-(x8)--5-(x8)|
E|-------------------------3-(x2)--1-(x8)--3-(x8)|

e|-----------------------|
B|-----------------------|
G|-----------------------|
D|-5-(x6)--4-(x2)--2-(x8)|
A|-3-(x6)--2-(x2)--0-(x8)|
E|-----------------------|

The above then slides into either the main riff or the lick:

e|----------------------------------------|  (x3)
B|----------------------------------------|
G|----------------------------------------|
D|----------------------------------------|
A|-3-(x8)--5-(x3)--7-(x5)--10-(x8)--3-(x8)|
