Green Day - Castaway Tabs

Castaway by Green Day

i figured out the main riff:
e-------------------------------------------------|
b-------------------------------------------------|
g------------------------------------------------o|
d--xxxx-9-x-9-x-9--xx-6-6--xx-2-x-2-x-2--xx-9-9--o|
a--xxxx-9-x-9-x-9--xx-6-6--xx-2-x-2-x-2--xx-9-9---|
e--xxxx-7-x-7-x-7--xx-4-4--xx-0-x-0-x-0--xx-7-7---|

i'm on a mission...
e---------------------------|--------------------------
b---------------------------|--------------------------
g---------------------------|--------------------------
d--2-2-2-2-2-2-2-2-2-2------|--9-x-9-x-9-x-8-9---------
a--2-2-2-2-2-2-2-2-2-2------|--9-x-9-x-9-x-8-9---------
e--0-0-0-0-0-0-0-0-0-0------|--7-x-7-x-7-x-6-7---------

Then just before the chorus, it's an E then F# power chord
e---------------------------|--------------------------
b---------------------------|--------------------------
g---------------------------|--------------------------
d--2-2-2-2-2-2-2-2-2-2------|--4~----------------------
a--2-2-2-2-2-2-2-2-2-2------|--4~----------------------
e--0-0-0-0-0-0-0-0-0-0------|--2~----------------------
                                  Then it goes into the main riff
