when I hit a zombie with a baseball bet or something else, he still stands right in front of me like he never got hit. I never notice when I hit him or if i hit him at all. It would be realistic, advantageous and nice if a hit would knock the zombie back or pushes him aside. Maybe with some more blood splatter that extravasates out of the zombies head, when I hit him there (Same with all Charakters like other Players). And the hit sound is too low and sometimes not realistic, but I think you know that yourself already...
