Cannibal Corpse - Puncture Wound Massacre, аккорды

Here's a tab I found for Punture Wound Massacre on some German site while
surfing for tabs a few weeks ago. I have no idea who the tabber is and I'm
not gonna take credit for it but I'm gonna post it anyway for those who
want to play it. I don't know if it's correct cause I haven't had much
time to try it out so hope it works out for people okay.
