Fallout 3 Perks

In Fallout 3, you will gain perks every level, as opposed to every three levels like 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 will not be met by equipping items, or using drugs.
