From the publisher: Bone Orchard is an EL6 encounter that can be dropped into most any sci-fi campaign that can accomodate the concept of nanites. It finds the PCs in a veritable Dawn of the Dead, as rogue medical nanites are animating corpses and driving them to eat animal flesh for fuel. The encounter includes 5 locations, 4 NPCs, 2 new weapons, 3 new xenomorphs, and a new disease. All this for less than 2 DSR credits!
