So I've been playing since like alpha 15 or so, and I love it, but I can't stand the fact that zombies make zero sound when indoors. It makes me feel like my character is deaf or something. How can it be that sometimes I can hear a zombie's activation snarl from about 20 meters away, but if I'm sneaking around in a house, any damage I take is ALWAYS the result of taking a blow to the back of the head from some random that levitated down a hallway without any footsteps or anything? Is this a design decision with an explanation, or a known bug that will be addressed in a future alpha? Because frankly, the current work around is to constantly do a 180 every few seconds, which looks ridiculous and is immersion breaking.
