Since before the game even launched myself and everyone I know agrees that the Last Man Standing music is BORING.
So I want to suggest replacing the soundtrack, perhaps having it change once you reach level 30 so the current soundtrack won’t be gone, to another soundtrack such as The Emperor of Mankind or Darktide Main Theme or Path of Trust.
These are great soundtracks that I believe would fit great and will make a big positive difference in how the game feels during a Last Man Standing situation.
Funnily despite my opinion on this since launch, a recent conversation with a friend had the idea to make it level 30-related and inspired me to post this
It should be a more urgent sounding cover of one of the game’s main leitmotifs, the way it is in Vermintide 2. Personally I’d pick Immortal Imperium to make a cover out of, though.
