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 to the explosion of a car or mini nuke whenever your health is reduced to 20 or less. Any allies in the vicinity will also suffer the effects of the blast.

 * When playing on Normal+ difficulty, you can be killed by the explosion before the health regain activates. This makes the perk entirely useless at higher difficulties (the perk merely kills you when your health reaches 20).
