i have to confirme the supsicion, i just started a new server recently after a while and it's shocking how tough the game is now. We can barely get out of our base and we all die at least once each game. We killed hundred of zombie around our base who is not inside a town and there is always more a few minutes after. It may be something about noise because even when i sneak the z seam to always see me before i see them. I never noticed anything like that the last time i played to PZ.
