Audio needs major work!

From my own experience, I mostly hear teammate footsteps, but not enemy footsteps until they're two steps away. 

I was watching someone stream REDSEC battle royale, and the audio is bad there, too. In the last match, a vehicle rolled up to him and made ZERO sound on its approach. Of course, he was killed because he didn't hear the vehicle arrive. 

That's really bad audio when you don't hear a vehicle approach you.
