Quests

 * Arizona Killer: the Courier will be required to meet with Cato Hostilius between Ranger Station Delta and Hoover Dam on top of the mountain. There, he will offer the Courier advice on how to assassinate President Aaron Kimball before resting. Upon waking, he will be dressed in civilian clothing, give the player NCR armor as a disguise, and rush over to Hoover Dam in the middle of the crowd awaiting the President's arrival. After the quest is completed, he will disappear from the game.
