Nuclear Anomaly

 is a perk added to Fallout 3 with the Broken Steel DLC.

With this perk you erupt into a devastating nuclear explosion 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 the Very Hard difficulty, you can be killed by the explosion itself (not the enemy).
 * With a high Damage Resistance, this perk can be useless. For some reason, Damage Resistance is taken into account with the explosion, and with a high DR, the explosion will take away more health than it will heal. It is suggested not to use Nerd Rage! with this perk because of it.
