Eye for Eye

Eye for Eye is a perk in the Fallout: New Vegas add-on Honest Hearts.

Effects
For each crippled limb you have, you do an additional 10% damage.

Behind the Scenes

 * It is possibly a reference to the Bible passage Exodus 21:24, "Eye for an eye, tooth for a tooth, hand for a hand, foot for a foot".
 * The name of this perk might also be a reference to the Hammurabi Code, a law system developed by Hammurabi where whatever a person does to another, that would be his punishment.
