Happy DOOMsday, everybody! It’s been a long, 12-year wait for another chapter of the iconic game series, but did you know much of DOOM’s original music was inspired by metal legends?

Plenty of DOOM and DOOM II’s original soundtrack was molded by some of rock and metal’s most sinister sounding music. The list of potential bands to lend inspiration to DOOM is rather long, but we’ve focused on cuts from Pantera, Metallica and Slayer.

Out of all the metal adaptations, Pantera’s music is the most obvious. Dimebag Darrell’s riffs from “Mouth for War,” “Rise” and “This Love” are all featured and you can hear the comparisons for yourselves in the clip above.

Below, we’ve got Metallica’s influence. In the very first level of DOOM, a reworked version of “No Remorse” hits gamers right in the mouth. Some feel like it’s closer to a part in “Master of Puppets,” but we found an ever closer similarity deeper into the game. A creepy cut of “Call of Ktulu” is also matched up in our video.

Finally, we’ve got thrash titans Slayer. Most of DOOM’s Slayer influence can be attributed to drummer Dave Lombardo. Dave’s opening fills in “South of Heaven” can be plainly stacked side-by-side with an old DOOM cut, while “Criminally Insane” seemed to be reworked for a separate piece of music. As for riffs, check out the similarity between a DOOM cut and “Behind the Crooked Cross.”
