I for one find the zombies to be way overpowered. When I am crouch running, a zombie that is quite far away will start running after me. I run to try and lose him, but it is a little faster than me. Zombies should also not be as smart as they are. I do not think they should be able to run after you even if you are swerving through buildings and you can't even see them anymore. Also, last thing, zombies are too strong. If you get punched you shouldn't start bleeding like you lost an arm. Or your leg could break. Too strong. That is all I have to say. I like the game but sometimes it just angers me that I start out and I am bleeding and running until I lose all my blood.
