Cardiac Arrest

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

Location
Convince your brain to return to your body or convince it to come back to The Sink. After, you can have your heart reinserted into your body. This perk replaces Heartless.

Effects
You gain +50% poison resistance, +50% bonus to healing items and robots have -25% critical chance against you.

Bugs

 * This perk grants -50% critical chance from enemy robots, rather than the listed -25%. (verified, the GECK lists 50%). For PC users, a fix for this perk along with Brainless and Big Brained is available here.

Behind the scenes

 * Cardiac Arrest shares the same Vault boy image as Heartless.
