Also, not sure why (false sense of security?), but I have had more jump scares in this alpha than the entire 2 years or so I've been playing this game.
I kinda wish there was some reverb added to zombie sounds when they are farther away for a more realistic representation of audio cues (and more footsteps), so I don't have to do laundry so often. Neebs adds reverb for a nice theatrical effect. I think the added audio space would be nice, but it's also kind of awesome the way it is, if you ignore the heart attacks.
But it does sound like they are right behind me when they are yards away....then they are right behind me at other times with no notice, no telegraph. Sneaky bastards.
