How to Get Bounties for the NCR
- 1). Travel to Camp McCarran and speak to Major Dhatri outside the main terminal building to obtain the "Three-Card Bounty" quest.
- 2). Travel west of Camp McCarran to the location markers on your map to locate the three Fiend leaders you must kill.
- 3). Use extreme caution when killing each of the Fiend leaders; to receive the full bounty in the quest, you must not kill them with a headshot.
- 4). Return to Major Dhatri to receive your bounty for each of the Fiend leaders you killed.
