The Exodus Overseer's Guide is the Game Master's Guide for running the Exodus Post-Apocalyptic RPG game. The rules within are designed to alter the Apocalyptic experience into a hoard of different Apocalyptic scenarios as well as teach how to be the Overseer. Many rules from the d20/Modern OGL document have been updated to fit into an apocalyptic setting along with new or expanded rules, and a hoard of examples for the Overseer to use. This product requires and works in conjunction with the Exodus Survivor's Guide. It is also recommended to have the Exodus Southwest Guide and Wasteland Bestiary, but is not necessary. This guide is fully compatible with other d20/OGL/Pathfinder products.
