I've noticed during combat that ship modules are a bit...bland. All too brightly lit during combat. I was thinking that bridge and guard stands could have a small red alert siren that would activate during combat. There could even be a separate corridor that has this feature.
We could take this a step further and make this have a buff that infects crew efficiency.
The siren could also be modded and downloaded via the Workshop, so if I so desired, I could have Voyager's red alert sound.
Interesting idea, yeah. Crew buffs/debuffs is something that might turn up during the monster update. Gotta have fear effects. :D
