In the words of the iconic Tenacious D song, The Metal:
You can't kill the metal
The metal will live on
Punk Rock tried to kill the metal
But they failed, as they were smite to the ground
New wave tried to kill the metal
But they failed, as they were stricken down to the ground
Grunge tried to kill the metal, hahahahaha
They failed, as they were thrown to the ground
Aargh! yeah
The creators of Doom Eternal know the score.
No one can destroy the metal
The metal will strike you down with a vicious blow
We are the vanquished foes of the metal
We tried to win for why we do not know
New wave tried to destroy the metal, but the metal had its way
Grunge then tried to dethrone the metal, but metal was in the way
Punk Rock tried to destroy the metal, but metal was much too strong
Techno tried to defile the metal, but techno was proven wrong
So there could be only one musical choice for the soundtrack and background music to a game as frantic and action packed as Doom Eternal, a game that literally pits you against the minions of hell itself.
Metal!
It comes from hell!
