Hey.. I also think that this game is a bit "unaturel" sounds wierd in a zombie game, but zombies in movies etc. ( are the slow walking, taking a few bullets to the chest without dieing, takes one shot to the head, and not able to do alot of fysical things as climing a ladder). They should patch it, so that they would run a bit faster than they walk, when aggroed, but still being escapable. just my thoughts:) :P
