This really should have been a high priority from the start. First - Plain and simple the zombies don't act like zombies at all. I hope that part is whats being changed with the new ai. It would be pretty messed up if the animals end up acting the same way. If anything the animals should be more aggressive than the humans. Of lesser importance, should consider the zombies having an actual animation of trying to eat you and not just smack you around. Smacking people around doesn't exactly cause people to bleed or get infected. Second - The zombies being able to walk through doors and building walls should of been a high priority to be fixed from the beginning. When is planned on getting fixed?
