Bounty

In Fallout 3 you can collect bounties from good or evil characters. Before that, you must have either the Lawbringer or Contract Killer perks.

Lawbringer
With this perk, the player can remove the finger of every (human) evil character he or she kills. The finger can then be sold to Sonora Cruz at Regulator HQ for 10 caps and a Karma increase. The bounty is higher for some characters:


 * Junder Plunkett's finger can be traded for 1000 caps.

Contract Killer
With this perk, the player can remove the ear of every (human) good character he or she kills. The ear can then be sold to Daniel Littlehorn at the Scrapyard for 15 caps and a Karma decrease.
