Doom is a game that attracts edgelords because the very subject matter involves rock music, demonic imagery, lots of blood and gore, and lots of violent ways to kill stuff.
I don't need to explain why that's an edgelord sperg magnet, do I?
To be honest I expected Doom to have a fanbase consisting of pretentious hipsters who are also metal elitists that would berserk at music that is modern pop and mainstream.
