When one exits on the other side, they will encounter a squad of NCR Veteran Rangers. From here, check the terminal if the player character has a Science skill of 100 and a detonator, they may use the terminal to detonate one group of Legion soldiers (the blast is centered near the first tower). Proceed to the north along the curved walkway above the dam. Exit via the double doors on the east side to Hoover Dam. At this point, one will begin to notice assistance appearing from companions and factions the Courier has helped out along the way. Follow the passage along the left, then go up the stairs, and exit via the elevator to the Hoover Dam visitor center. Climb the stairs on the left in power plant 01, then proceed north across the balcony. Proceed to power plant 02, then power plant 01, killing any Legion troops on the way.

On the second floor on the east wall, from where the Courier reentered there is an exit to the Dam exterior. Completing this will require manual intervention return to power plant 04 by the closest door which is right below the console.

Passing a Science check (65) allows the player character to use the terminal to engage the turbines. The console is on the second floor of power plant 03, on the southern wall. To complete the optional part of the quest, follow the staircase immediately to the left in power plant 04 then across the room to enter power plant 03. If they wish to follow his suggestion and do the optional part which involves flushing the Legion invaders through the turbines, agree to his suggestion.

The Courier is given the chance to wait, as this begins the end quest for the game. Moore's office to General Oliver's compound, where the general will begin a briefing.
