There's something I want to talk about it, is that NPC sometimes doing something beyond the player,
for example, I always seen the NPC getting chase by the zombie hordes, and they can somehow walking straight into the hordes, and come out safety, and they can even doing that when attacked by the zombies, if the player is attacked by the zombies, they will getting speed penalty, whichs moveing slower that usually, the NPC, somehow, dosn't have the same problem, they can always getting out the hordes surround anytime, and they can even doing that with sprints, that's really blows my mind, right now, I can always seen a bunch NPC that led a whole hordes going what ever they please, also they sometimes stand still after climb over fence or something.
I mean, come on! Why does the npc getting such favour?
