Anyone noticed that Zombies are alot more aggressive than usual? I've been encountering zombies noticing me from afar (I had to use a sniper's scope to clearly see the zombie). this was regardless if I was walking or jogging. i've also encountered zombies not making any noise while approaching me. I was eating (crouched) and was surprised to find a zombie hacking at me from behind. or is this just all me? lol
