Much of the source material is the same. However, we have added three new colonies (The Brotherhood, Sanctuary, and New Miami), four new organizations(The Fed-UPS, Agents of the Beast, Children of Purgatory, The Black Spike), not one but TWO basic magic systems (Word of God Magic, Savage Gods Shamanism), Details on a number of the supernatural denizens of The End (Locusts, Death Vampires, Soulless, etc), and some other information. We removed the adventure due to space requirements, but you will see it soon!
