The first thing that you should know is that this is not actualy a d20 game. It is actualy a homebrew world of my own creation that we are play testing as I build it. I have never done something like this before so please, be gentle.
This is a world based off of the books of Max Brooks. in particular my material comes from “The Zombie Survival Guide” and “World War Z” I just started this page so dont expect to see everything up just yet.
After that, take a look at your wiki. There is some more helpful info there.
