I believe they scale backwards. Where as 1 is insane amount of zombies, and 5 is none. You can pull up a sandbox creation to use as reference when changing these values. That's what I did. The numbers essentialy just mark their places in the dropdown windows. I am wanting to have no zombies on my map as my friends and I are trying to look around the map without any hassle to find a place to make a base, as the PZ map doesn't actually let us see inside the buildings so we don't know if it is good to create a base and hold up there. If your suggestion works Loki I will love you as I have spent hours Googling! You just need to make sure you're editing the correct file in the correct directory. And it WILL work. After it is changed do you need to soft reset it, I have changed it.
