Nuclear Anomaly

 is a perk added to Fallout 3 with the Broken Steel add-on.

With this perk you erupt into a devastating nuclear explosion similar of the explosion of a car or mini nuke whenever your health is reduced to 20 or less. Note that any allies in the vicinity will also suffer the effects of the blast!

Bugs

 * When playing on Normal+ difficulty, you can be killed by the explosion before the health regain activates.
