General information[]

In Fallout 3, the Lone Wanderer will gain a perk every level (as opposed to every three levels in Fallout and Fallout 2, and every two in Fallout: New Vegas).

There are :

Also, unlike previous games, traits that provide 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 SPECIAL requirements cannot be met by equipping items or using drugs (with the exception of the Lucky 8-ball).
