This looks really rad, a bunch of us have been itching for a server like this. Cheap's checking it out now and I'll get on later.
Are there any rules about building? With such a finely crafted world with ruins and stuff I hope there's some basic aesthetic rules/guidelines. I love the idea that the world is actually hostile/dangerous. Zombies present one danger, but radiation and acid rain and stuff present another. Looking forward to a hardcore survival experience!
PS what's it take to start a town?
