I'm a fan of evil / terrifying biomes. But my question is this, I normally have a meat industry set up (birds / bears / whatever i can farm). They are normally pastured underground, but with the changes bringing in zombies is it even possible to have a meat industry in evil biomes anymore? or does everything you kill come back as a zombie?
Some evil biomes reanimate, some don't. I have one evil biome with live grass, freakish rain and no reanimation, and one with normal weather and dead flora that does reanimate. Haven't seen yet how reanimation is transmitted -- is hauling a corpse through a reanimating biome without dropping it enough to start the reanimation process?
How far away does a corpse have to be from an evil biome before it stops rising?
One tile. I have a non-reanimating mountain and a reanimating marsh, and corpses left on a stone floor next to a sand floor didn't do anything for the month I left them there. Moving the corpses to a sand floor saw them up less than a week later.
Further testing is required with regard to z-levels. There's a non-evil mostly-frozen lake on the site, and I'd like to see how the ice tiles compare to the stone tiles beneath and around them. The stone is presumably the same sort underlying the marsh, which means reanimation. Without testing, I'd assume that floors dug from the ice are corpse-safe and floors dug from the stone are not.
Not a clue about how the biome boundaries function above ground in this case.
