@Midnight9746 Footstep audio is very loud, scan audio is loud, ambience is quiet which is fine, but heartbeat scan is almost as quiet as ambience, and Kings Canyon, particularly the deserty areas, seems to be the only place I hear that ambience, so I often mistake it for a heartbeat scanning me.
Other maps, like Broken Moon and E-District, I've yet to hear that ambience. Whenever I hear it on those maps, it's always followed by either gunshots or a seer tactical. Kings Canyon however, 9 times outta 10 it's the ambiance.
I use a headset. Works very well, to my liking. I don't know if it's surround sound though, as sometimes I hear something on the left that's actually on the right, or I hear something in front that's actually behind or beside me. Although normally it does a good job. Could just be the sound engine. I don't know.
Seer heartbeat doesn't sound like machinery. More like a pulsing or crickets? Eh, the desert ambiance basically. That's why it gets me there, and only there.
I also don't get distracted on storm point either. Most maps are safe from ambiant distraction, it's only kings canyon that gets me that bad.
Although, I think there was one spot, probably near a prowler den or creature cage, where I heard footsteps. I think it was the creature though, as no players were around. If there wasn't a creature, then I don't know where it was, it's been a while since I've heard it or been distracted by that. It's only the heartbeat vs desert ambiance that gets me lately. Maybe when they bring another map back into rotation might I figure out what the other thing was. I've completely forgotten what the other was and what map it was.
