The rules are fairly simple. 9 is the target number to roll for all actions, after modifiers. There are three types of characters. The first, and my personal favorite of the three, is Norms. They are average people such as you or me. They will probably survive if they're smart, but shouldn't run headfirst into the zombie hordes expecting to survive like in zombie movies. The second type is Survivors. They're essentially the main character in a zombie video game. They're tougher than Norms , with 5 extra points for Attributes (Your basic stats), Skills (No explanation required) and Qualities (Somewhat similar to feats in D&D). They don't have to be as careful as Norms, but will still probably die if they're stupid about it. The third type is the Inspired. They have the same Attribute points as Norms if I remember correctly, with fewer points for Skills and the same points for Qualities. What makes the Inspired special is Metaphysics, which are basically magic. In AFMBE, the rules for Metaphysics only cover divine type magic, but you can easily replace it with magic from Witchcraft (Another great Eden game, this one's free also). Some may find the Inspired out of place in a zombie game, but because this is an Eden game, they're there anyway. I don't personally like to play in games with Inspired, but they are very balanced compared to Survivors if you do want to play them. There are also detailed rules for creating zombies, and a bunch of campaign settings, called Deadworlds, to use in the game as well.
