For example, Set Lasers for Fun increases the odds of scoring Critical Hits with energy-based energy weapons to earn the perk, a player must do 16,000 damage with one handed energy weapons over the course of their game. Most of the perks obtained this way are related to the skill or task that was completed to earn it. Challenge tasks can be accessed from the Pip-Boy menu on the 'Misc.' page, accessible from the 'Data' section. Challenge perks are unlocked by fulfilling certain requirements.

Companions told to wait are still counted as active companions. Unless the companion is dismissed, the perk will remain in effect regardless of the distance between the player and their companions. The perk remains in effect so long as the companion is currently following the player. For example, Enhanced Sensors is only in effect while the Courier is accompanied by ED-E. Companion perks, as their name suggests, are granted by the player's companions. You can get up to a total of 25 non-challenge perks with all 4 DLCs installed. Other types of perks are granted through completing various tasks, and do not count against the limit of regular perks. Only regular perks may be selected during level up.

There are 88 regular perks, 8 companion perks, 16 challenge perks, and an unknown amount of special perks. To counter how easy it was to max out the player's skills in Fallout 3, most of the skillboosting perks have been removed or replaced.

Unlike in Fallout 3, the Perk Rate in Fallout: New Vegas is one perk every two levels. For an overview of Fallout: New Vegas content, please refer to 'Portal:Fallout: New Vegas'.
