Complete the That Lucky Old Sun quest in fallout new vegas. Learn how to get ARCHIMEDES project locations and reset HELIOS One terminals.

  • Speech 25 to extort caps from Fantastic.
  • Speech 35 to get Ignacio Rivas to talk about his allegiances.
Walkthrough
  1. 1
    Head inside the HELIOS One building and loot the reception room, paying attention to the metal shelves and the Gun Cabinet behind the counter for .308 Rounds. The building contains a significant amount of free ammo.
  2. 2
    Proceed through a door to the east and follow the hallway until you reach its end. Turn north and continue to the end of this hallway, passing a locked door [Very Easy].
  3. 3
    Go west through a room containing a pool table.
  4. 4
    Head north up another hallway, bypassing a door to the east, and climb the stairs to the north.
  5. 5
    Continue through a room with a ruined floor patched with boards, and enter a bedroom to the west.
  6. 6
    On the bed, find a D.C. Journal of Internal Medicine.
  7. 7
    Read a terminal to learn about the ARCHIMEDES project.
  8. 8
    Take the note “Eastern Reflector Control Terminal Password” from a desk or a Footlocker at the foot of the bed. Investigating the terminal and reading its entries will reveal the locations of Hidden Valley and Black Mountain on your map.
  9. 9
    Make your way back downstairs and head through the first doorway to the east. Follow the linear path, looting containers and ammo, to reach a machinery-filled room.
  10. 10
    Ignore the metal stairs and continue west through the room, then go through a door, down some stairs, and through another door to reach the control room.
  11. 11
    Speak with the NPC (non-player character — anyone the game controls, not you) named “Fantastic”. Agree that you are there to replace him and succeed at a [Speech 25] check to extort 100 Caps from him.
  12. 12
    Ask Fantastic about his credentials, work, and progress. He will reveal that the solar plant is operating at only 1% efficiency and that calibrating the solar panels could make HELIOS One a major asset for the NCR, especially if power is directed to the New Vegas Strip and Camp McCarran. Agree to help him, and he will give you the “Western Reflector Control Terminal Password”.
  13. 13
    Head into a smaller room to the north to find Ignacio Rivas, a member of the Followers of the Apocalypse. State that your interests in HELIOS One are scientific, then succeed at a [Speech 35] check to learn about his allegiances. Avoid mentioning the NCR or promoting war. Ignacio will give you the note “Eastern Reflector Control Terminal Password” and express concerns about the HELIOS One plant's secrets.
  14. 14
    From Ignacio’s room, head north down a tunnel and up some stairs to a door leading to the fenced-in area of HELIOS One.
  15. 15
    Once outside, head north past solar panel arrays until you find NCR troops near a fenced-in terminal. Loot tents to the north-west of the terminal for a First Aid Box and two Ammo Boxes.
  16. 16
    Return to the fenced-in terminal. Disarm traps, including Bear Traps and a Tripwire rigged to a shotgun at the entrance to a shack, and Frag Mines near the terminal.
  17. 17
    Activate “Terminal 1” and select the option “Reset Mainframe Connection”.
  18. 18
    Head east through solar arrays to find another NCR camp around a second enclosed terminal. One tent contains an Ammo Box [Easy].
  19. 19
    From the tents, go north-east to find the enclosed terminal. Kill the three NCR Guard Dogs guarding it.
  20. 20
    Activate “Terminal 2” and reset this mainframe connection.
  21. 21
    Travel south-west from the second terminal, passing the NCR camp, to find a small building labeled “Solar Collection Tower”. Prepare for powerful robots inside.
