A solution for the "surprise 2-tap" in 2v8
No, I'm not going to complain about being chased by 2 Killers when I play Survivor in 2v8. That's part of it, and It's really fun to play Killer with my duo and actually be able to coordinate.
What I'm not a big fan of is getting 2-tapped or just flat-out running into the other Killer when I had absolutely no idea that the second Killer was even nearby. This is the fifth(?) iteration of 2v8 and there's still no feature to let Survivors know when both Killers are nearby/in chase unless you can see them with your eyes (or a Scout can) or until you get double-tapped.
Layer the terror radius music.
Do something like Legion's Mix Tapes.
If you're inside Killer 1's terror radius and Killer 2 gets close enough for their radius to overlap you as well, put another audio layer over the radius music. Same if you're in chase with Killer 1 and you enter Killer 2's terror radius and/or Killer 2 enters the chase as well, just make the audio layer for the latter more intense.
I feel as though something like this would make stealth and chase in 2v8 as Survivor more stressful, but in a fun/good way… and cut out a fair bit of frustration.
