Note: Many of these officers are involved in the quest Restoring Hope, and completing this quest will cause the opposite quest to fail. Other quests that begin in or involve the camp can be completed if they are finished first.
Upon talking to Dead Sea in the Nelson barracks, one can say that they are going to slaughter Camp Forlorn Hope. He will respond, saying that "A vow without action is breath across the lips, nothing more." This starts the quest. To complete this quest, the Courier must travel to Camp Forlorn Hope, and kill the four named officers there. Joseph Polatli, Carl Mayes, Reyes, and Alex Richards. These are the only four individuals that must be killed, the rest can be spared and the quest continues as normal. After the four are killed, the Courier returns to Dead Sea, and he will give them the Liberator as a reward for the slaughter.
Kill all NCR Officers at Camp Forlorn Hope.
Return to Dead Sea and inform him of your victory.
Completion of this quest allows the Courier to become leader of the Great Khans, as Papa Khan will name the Courier his successor after completion. Silently killing him after this exchange results in leadership, and is one possible solution to secure the Khans' loyalty during the final battle, even if siding with the NCR.
Completing the quest Back in Your Own Backyard by rescuing the NCR troopers or mercy-killing them makes Dead Sea permanently hostile toward the player, preventing this quest from being completed.
Completing the quest does not create a Legion presence at Camp Forlorn Hope. NCR forces will continue to spawn at the location and will only be wiped out during the epilogue.
As Restoring Hope requires the player to kill Dead Sea and this quest requires them to kill Joseph Polatli, these two quests are mutually exclusive. However, the other quests at Camp Forlorn Hope can be completed, as they do not involve fighting Dead Sea.
