After the kick ass keyboard intro:

When Till starts to sing:

Intro:        
-----------------------------------------------------
-----------------------------------------------------
-----------------------------------------------------
--9-10-9-10-9-10-9-10-12-12-12-----------------------
--9-10-9-10-9-10-9-10-12-12-12-----------------------
--9-10-9-10-9-10-9-10-12-12-12-----------------------
Do this until he says "Ein hesser schrei... FEUER FREI!"
This is sounds like it MIGHT have SOME distortion.

Main Riff:    -----------------------------------------------------
-----------------------------------------------------
-----------------------------------------------------
-5-6-5-6-5-6-5-6-8-8-8-------------------------------
-5-6-5-6-5-6-5-6-8-8-8-------------------------------
-5-6-5-6-5-6-5-6-8-8-8-------------------------------
Again, when he says "Ein hesser schrei... Feuer Frei!"
and goes into the whole "BANG BANG" thing, start playing.

The Inbetween:    -----------------------------------------------------
-----------------------------------------------------
-----------------------------------------------------
-5-5-5-8---5-5-5-8---5-5-5-8-------------------------
-5-5-5-8---5-5-5-8---5-5-5-8-------------------------
-5-5-5-8---5-5-5-8---5-5-5-8-------------------------
This is just that between guitar part before they start
saying Feuer Frei! If you listen to the song, you'll get
what I mean.

At the end of the song before the final "Bang Bang", not too
sure how to play that part. I don't think it's too hard though.
This is pretty much it. The video for this kicked ass. Have fun
you jerky ass bastards.
