Very good point actually.
Not sure how load I would have to have my speaker system to hear footsteps, but the neighbours would not be impressed. Not one bit.
in all honestly, there are maps that are better for awareness than others.
Maps I've found best for awareness:
Maps terrible for awareness
*Drone being the only exception because the entire drone side with doors is pretty obvious if someone is coming through. The doors are so loud it's really only useful for the busy side.
The smaller maps generally are not nearly as good because of the chaos and constant flux of both teammate and enemy players all over the map. Also, because of these smaller maps I tend to rely on communication over sound.
