For a moment I thought this was a Venom cover (if you haven't heard it, you should, it's arguably the song that started thrash metal chugga riffage). Nevertheless, very fucking cool song, has a bit of a Castlevania feel and I could definitely see it in a SOtN style game in a catacombs sector or such. I've never been a fan of djenty modern sounding riffs and pinch harmonics, but I can let them slide here, they're quite tastefully placed and the one section that does have them makes them fit. Excellent work dude!
