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, opposite of the Hoover Dam, off in the distance with a ranger standing guard is where the assassin will be. Go up top as soon as possible and wait for him to appear. He is a normal NCR Ranger and will appear as an enemy, kill him right away. (NOTE: The guard standing there originally is not the sniper.) Go down and speak to Ranger Grant and tell him about the sniper and he will prematurely end the speech and have troops search the area for any other Legion spies. There will also be one engineer that will charge the President Kimball with a Knife but will get shot down right away. 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.
