Although not a common occurrence, nuclear weapons have been used on the occasion in the numerous wars between worlds.  It has been discovered that the radiation released in the blasts would on a very rare occasion, mix with necromantic magic and create zombies from the corpses of those killed in the attack.

These strange zombies are somewhat stronger and tougher than other zombies, and are made all that much more dangerous by the simple virtue they are actively radioactive! Getting within 20 feet of these creatures will force the hapless victim to make a Fort saving throw or contract radiation poisoning.

Sometimes these undead monsters are mixed in with other types of zombies, although they are usually easily distinguished from the others due to their appearance. Typically these zombies have a burnt look about them. Patches of flesh is crispy and blackened, the eyes are milky white and appear to glow, even in bright light. The clothing – what little remains – is in tatters and usually covered with scorch-marks. Furthermore, any open wounds will glow a sickly green.

These types of zombies are always hungry, and are always looking for flesh to feast upon. They are drawn by both life-force and blood. If there are any targets with open wounds, or who are bleeding, the range of detection goes from 60 ft. to 120 ft.
