Napalm Death - The Infiltraitor Tabs

Words from the exit wound
Tune down a step and a half

A few things to tell about my transcription of the song is the fact 
that the structure of the main riff isnt written correctly but just
use your ears to tell when to play each riff also there may a couple
of mistakes like during the blast riff when there are barely audible power
chords played at fast speed but overall this is accurate.
