I see some familiar perks...oh look you might be right on ghoulification perk.
Ghoulification - Become a zombie with rotting flesh as you scare foes and citizens alike with no consequence!(Oh and you heal from radiation).
Just wanted to talk about that one. Never mind that Bethesda screwed up Ghoulification even more (it is suppose to be very rare, depending on various factors and takes years of exposure), it should come with some serious stat losses to compensate for the radiation and toxin immunities such as Charisma and Strength losses.
Edit: and I am sure there will be an ingame cure for when people become tired of playing a Ghoul.
