Bloodlands

from the introduction:
Welcome to Bloodlands, a dark fantasy Deadworld for All Flesh Must Be Eaten. This is a world in which the quest of a group of heroes a thousand years past went horribly wrong, and the consequences of that quest, combined with a mysterious great sin by the elven peoples during a world war, caused the entire face of the continent (and possibly the world) to be reshaped, and allowed the dead to arise. This Deadworld assumes ownership of the following books: the AFMBE core rulebook, Dungeons and Zombies, and Atlas of the Walking Dead. While it will be possible to play in this world with only the core AFMBE rulebook, some important details and aspects of the world will be lost.
