If you're an attentive Quake Champions fan, you may have noticed that videos released over the past few months have featured music that's not featured in the game. Today, Bethesda finally revealed the secret: Andrew Hulshult, the "sweet metal Viking" behind the music heard in Brutal Doom and Dusk, is creating a new soundtrack for the game. 

"This update will be a top to bottom, in-game music preview," community manager Joshua Boyle wrote. "Everything from the menu idle music to each map's theme music during the match; including the different theme music you hear whether you win or lose. Top to bottom—it’s the whole shebang."
