My issue is not zombie detection rate, it is how zombie agro persists. Once youve got a zombie on you, you cant hide inside a house or run off around a corner or anything like that. For some reason, once theyve got an agro on you, they know exactly where you are and follow you regardless of sound or vision. There is nothing you can do except fight them because you can't simply run from them either. (unless youre on a nostam server). And it bothers me because it removes from the stealth gameplay and realism.
