Fallout 3 Perks

General information
In Fallout 3, you gain perks every other level (opposed to every three levels in previous games). Also, unlike previous games, traits that gave you both bonuses and penalties at the same time are no longer in the game. Instead, some of them (like Bloody Mess) were changed into perks.

In Fallout 3 a perk's S.P.E.C.I.A.L. requirements cannot be met by equipping items or using drugs (with the exception of the Lucky 8 Ball).

Quest perks
You can get these perks as a reward for quests.

Important note about quest perk codes: Trying to add them before doing the quest required may cause game to crash or corrupt.

Add-on perks
Perks available through add-ons.

Regular perks
These perks are added only in Broken Steel.

Cut perks
These are perks cut from Point Lookout which can only be obtained on the PC with the console.
