Fallout: New Vegas description

Brainless is a perk in the Fallout: New Vegas add-on Old World Blues.


In the initial dialogue with Dr. Klein as part of the quest Welcome to the Big Empty, you find out that your brain, heart, and spine have been removed and replaced. This perk represents the replacement of your brain. While you technically have these perks from the start of the add-on, they are unlocked in the course of the conversation.

Your head cannot be crippled, you gain 5% DT (with a minimum of +1) and +25% resistance to chem addictions.
