Good time for you!
I found that sounds like zombie breathing was static in 0.60. I mean the situation when zombie is on the right side fron you, and sound of his breathin start playing, it will be in your right headphone even if you turn around duering that time. It was hard to detect from which side zombie will come. Acctually it's like the bullets sounds from one of your
latest status reports.
But in 0.61 it was fixed as for bullets sounds as for zombies sounds. BUT NOT FOR AMBIENT SOUNDS like thunder sounds etc. Also zombie breathing is even quiter than their footsteps.
Please, deal with it.
