Metal Hammer have done it again with another kick ass cover. The metal magazine based out of the U.K. has always had great covers, but this one just tops it. This month features heavy metal giants Slipknot, but its not just your normal run of the mill cover. Walking Dead artist Charlie Adlard drew the entire band as if they were in the Walking Dead comic book. Take a look for yourself, its f@#%ing badass!
