Undead

Undead were a semi-sentient species composed of both living and deceased Humans who got corrupted by the Slag. Whether the infected person only got changed or was directly killed heavily depended on the Slag's plans and the person's biology. Potent personalities were more likely to hold on after a person's infection. The infection was trasmited via biting. In order to keep the undead active the Slag inside of them had to feed them, though even when they weren't hungry they still attacked surviving humans, though they only ended up biting them rather than devouring them.
