Fallout: New Vegas Perks

General information
Unlike in Fallout 3, in Fallout: New Vegas you gain perks every two levels. The final number of perks is currently unknown. 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.

Companion perks
Fallout: New Vegas is not the first Fallout game to introduce the concept of companions having perks, but is the first to have perks that affect the party as a whole.
