Abolish government by SLAYER
the tuning is one hole step down- D,G,C,F,A,D
the chords tend to be strummed many times quite fast,
so figure the rhythm out yourself- shouldn't be too hard.
opening riff 
D--------------------                     -------------------
A------------11-12-9-                     -------------------
F--10-10-10---------- x3, then last time:--10-10-10--12--11--
C--10-10-10----------                     -10-10-10--12--11--
G--8--8--8-----------                     -8--8--8---10--9---
D--8--8--8-----------                     -8--8--8---10--9---

then when shouting comes in, this riff:

F--------3--4----                     ---------------
C-3-3-3--3--4--6-  x3, then last time:-3-3-3--5--4---
G-3-3-3--1--2--6-                     -3-3-3--5--4---  
D-1-1-1--1--2--4-                     -1-1-1--3--2---

then, it goes quiet, with just a guitar playing this riff:

F-----11--10--8----    
C-10--11--10--8--8-
G-10--9---8---6--8-
D-8---9---8---6--6-

then it goes loud again for a while but with the same riff.
then a new riff:

F-10--11---------------
C-10--11--11--12-------
G-8---9---11--12-------
D-8---9---9---10------

there is also a 'bridge' section with these stab chords:

F-----11-------------------
C-10--11--8-8-8-8-8-8-8----
G-10--9---8-8-8-8-8-8-8----
D-8---9---6-6-6-6-6-6-6----
