[The main riff that goes through the whole song pretty much:]
E|-----------------------------------------------|
B|--6-----6-----6--6-----9--8--6h8p6h8p6h8-------|
G|-----------------------------------------------|
D|-----------------------------------------------|
A|-----4-----4--------4--------------------------|
E|-----------------------------------------------|
 
repeats multiple times and then you finish it off like this:
E|-----------------------------------------------|
B|--6-----6-----6--6-----------------------------|
G|-----------------------------------------------|
D|-------------------------7---6---4-------------|
A|-----4-----4--------4--------------------------|
E|-----------------------------------------------|

[after the whole band joins in you play the main riff riff again and one of the guitars plays
the lower octave:]
e|---------------------------------------------------------------------------|
B|---------------------------------------------------------------------------|
G|---------------------------------------------------------------------------|
D|---------------------------------------------------------------------------|
A|-4--------4--------4--4---------7----6---4h6p4h6p4-------------------------|
E|-----2---------2-----------2-----------------------------------------------|
 
[repeat multiple times and then finish it off the same way as before:]
e|---------------------------------------------------------------------------|
B|---------------------------------------------------------------------------|
G|---------------------------------------------------------------------------|
D|--------------------------------7---6---4----------------------------------|
A|-4--------4--------4--4----------------------------------------------------|
E|-----2---------2-----------2-----------------------------------------------|

[before the band stops playing and its only Stu singing you finish off the main riff with this:]
E|-----------------------------------------------|
B|--6-----6-----6--6-----9--8--6h8p6h8p6h8-------|
G|-----------------------------------------------|  (x2)
D|-----------------------------------------------|
A|-----4-----4--------4--------------------------|
E|-----------------------------------------------|
E|------------------------------------------------------------------------|
B|--6-----6-----6--6-----9--8--6------------------------------------------|
G|------------------------------------------------------------------------|
D|------------------------------------------------------------------------|
A|-----4-----4--------4---------------------------------------------------|
E|------------------------------- 0s7--7--7--7--0--2h5--5--5--5--2--0--2--|

JOIIIN THE LAST MIGRATION! 
[As Stu is singing sometimes the band does just this part on a few spots during the song:
e|---------------------------------------------------------------------------|
B|---------------------------------------------------------------------------|
G|---------------------------------------------------------------------------|
D|---------------------------------------------------------------------------|
A|---------------------------------------------------------------------------|
E|0s7--7--7--7--0--2h5--5--5--5--2--0--2-------------------------------------|

The AUUUUTOMATIOOON! - part:

G|-----------------------------------------------------------------------------------------------------------|
D|----------------------------------------------------------------------------------------------------7--6--4|
A|---------------------7--6--4--------------------7--6--4-------------------7--6--4--------------------------|
E|2--2--2--2--2--2--2-----------4--4--4--4--4--4-----------5--5--5--5--5--5---------7--7--7--7--7--7---------|

You repeat this twice and on the second repeat finish it off with this part from earlier:
e|---------------------------------------------------------------------------|
B|---------------------------------------------------------------------------|
G|---------------------------------------------------------------------------|
D|---------------------------------------------------------------------------|
A|---------------------------------------------------------------------------|
E|0s7--7--7--7--0--2h5--5--5--5--2--0--2-------------------------------------|

The riff before the final chorus differs from all other riffs till now but basically follows the exact
same pattern as the main riff ( this is at 2:40 btw) :
e|---------------------------------------------------------------------------|
B|---------------------------------------------------------------------------|
G|---------------------------------------------------------------------------|
D|---6-----6-----6-6----9--8--6----------------------------------------------|
A|------4-----4------4-------------------------------------------------------|
E|---------------------------------------------------------------------------|
[ repeat multiple times and before chorus starts finish it off like this:]
e|---------------------------------------------------------------------------|
B|---------------------------------------------------------------------------|
G|---------------------------------------------------------------------------|
D|---6-----6-----6-6----7--6--4----------------------------------------------|
A|------4-----4------4-------------------------------------------------------|
E|---------------------------------------------------------------------------|

final AAAUUTOMATIOOON! - riff again untill end of song
E|-----------------------------------------------------------------------------------------------------------|
B|-----------------------------------------------------------------------------------------------------------|
G|-----------------------------------------------------------------------------------------------------------|
D|----------------------------------------------------------------------------------------------------7--6--4|
A|---------------------7--6--4--------------------7--6--4-------------------7--6--4--------------------------|
E|2--2--2--2--2--2--2-----------4--4--4--4--4--4-----------5--5--5--5--5--5---------7--7--7--7--7--7---------|
