There will be new perks in Fallout: New Vegas but a lot of the old perks will make a return exactly the same as before or with slight modifications. This is done to counter how easy it was to max out the player’s skills in Fallout 3, most of the skill-boosting perks from Fallout 3 have been removed and replaced. Unlike in Fallout 3 you now gain perks every two levels. There are 88 regular perks, 8 companion perks and other unknown amount of quest perks.
