E|---------------|-----------------|
B|---------------|-----------------|
G|-9-8-----------|-10-12-----------|
D|-X-X-6--7--7-7-|--X--X-6--7--7-7-|
A|-7-6-X--X--X-X-|--8-10-X--X--X-X-|
E|-0---4--5--5-5-|-------4--5--5-5-|

So just back and forth between those two riffs for a while...

Then, I'm very unsure about this:
E|----------|
B|-3--3-3---|
G|--------3-|
D|----------|
A|----------|
E|----------|

SOMETHING like that 4 times.

And, of course, the bridge:

E|-------------------------------|
B|-------------------------------|
G|-------------------------------|
D|-4---4/7-7---7/6-6---6/11---11-|
A|-X---X/X-X---X/X-X---X/-X----X-|
E|-2---2/5-5---5/4-4---4/-9----9-| X4
