So I recently did the Gentleman quest and really with that and another quest the zombies in this game act very differently then most games.
They seem to posses some intelligence and a remain of humanity but do hunger for brains and such but still posses the logic of reasoning and knowledge of weapons and even speak. This seems very refreshing to me seeing how some of what XIV decided to trow to the side and make some nice different zombies yes manly for comedy but I enjoy that they are not just depressing beings.
