Zombie speed is ok but some zombies, not all, don't make a noise when they are near you or maybe they just respawn right behind me and I don't even know it. Which sucks because I get hit and my stuff gets ruined. The zombies have eagle eyes so stealth is not an option. They still go through walls and doors which is really a bummer. How hard is it to make the walls.... Walls? Also, since the zeeks are faster can we make quick inventory items in our hands faster or at least take it out as we are running not slowing down?
