Detailed walkthrough

 * OPTIONAL: You will be given this quest once you finished the Wild Card:Side Bets quest from Yes Man. It requires you to upload an Override Chip into the El Dorado Substation controlled by the NCR. An optional objective to the quest is for you to save President Kimball when he arrives to give his speech. If you go to save the president you will talk to Ranger Grant and he will ask you to help if you are friendly with the NCR. He will ask you to conduct a search but this is not needed. Go outside and wait for Ranger Grant and talk to him. Immediately after doing this the president's Vertibird will arrive with him inside. The tower closest to the Hoover Dam Visitor Center you were just in is where the assassin will be. Go up top by asking the guard to see the vertibird and using 50 speech to convince him to say yes, once you're up there you can examine the vertibird with 50 repair or 50 explosive. You discover a bomb on the vertibird. Go down and speak to Ranger Grant and tell him about the bomb and he will prematurely end the speech and have the president take off in the vertibird. Saving the president will result in the NCR Idolizing you.


 * The main part of this mission is very simple. Go to the El Dorado Substation and upload the Override Chip into the terminal located inside. There will also be a few NCR troops inside though that will shoot on sight so try to sneak in with a Stealth Boy if possible. The best way is to wear NCR armor, the guards don't attack you that way. If you did the optional part of this quest and kill the troops in the substation it will not matter to your Reputation because you are so liked.


 * OPTIONAL: Yes Man asks you to convince the Followers of the Apocalypse to give full assistance to the New Vegas region; simply go and talk to Julie Farkas. There appears to be no way that she'll decline, so once you're done just report back to the Luck 38 and complete your quest (and enjoy your Wild Card achievement).
