Detaillierte Lösung

Starten der Quest

At the entrance on the south side of HELIOS One there is a NCR officer named Lt. Haggerty, who is the head of the NCR detachment guarding the plant. The player character can ask her for access to the plant. She is inclined to turn the player character away, but the player character can get her to change her mind with one of the following options:

  • Sprache 30 - Lie and say the player character's brother works there.
  • Wissenschaft 30 - Point out that the tower isn't working right, and offer to help.
  • If the player's NCR reputation is more positive than negative, or with Speech 35 or more, the player can claim to be with the NCR and be let in.
  • Have an NCR disguise.
  • The Courier could shoot their way in past the NCR guards (Courier loses more Karma this way)

Once the player has convinced her, she tells the player to talk to the "idiot wearing sunglasses."

Optionally, the player can sneak in through a back door with a very easy lock (player loses Karma). From there the player should find the idiot with the sunglasses, Fantastic, and talk to him to begin the quest.

Warning: To get the quest reward from Ignacio, you have to tell him that you do not work for the NCR.


In the back of the plant is a science lab of sorts, where Fantastic and Ignacio Rivas are trying to get the output of the plant up. Fantastic is a transparent fraud who clearly has no idea what he's doing. Rivas is an actual scientist, but is really working for the Followers of the Apocalypse, who worry that the plant is not merely a power plant, but a pre-War super weapon, which, as it turns out, it is.

Fantastic and Rivas explain that to get the plant running, the mirror control systems need to be connected to the mainframe, and then the mirrors re-targeted from the mainframe terminal in the plant itself. The two mirror control terminals require a password. Each man holds a password for one of the two mirror control terminals. Fantastic will give his up easily enough. Note that Fantastic's password is not in his inventory; it must either be obtained via dialogue or found in the same room as Rivas' password in a footlocker on the second floor.

Rivas will only give the player his if the player gains his trust by professing to be peaceful (or at least not trying to get involved - both available if the Courier states they only work for themselves), states that they want what he wants (must know Rivas is with the Followers, requiring a Speech check or Confirmed Bachelor perk), or if the player claims to be with the Brotherhood of Steel. This may only be done on the first conversation. The player can also pickpocket the password from him, or a duplicate password can be found in a second floor office, lying on a desk.

Die Außenterminals

Both terminals are inside small shacks on the outer perimeter of the mirror field. The west mirror control terminal requires the password obtained from Fantastic. The east one can be unlocked with the password obtained from Ignacio Rivas or from the office of the main building on the second floor by the room with the giant hole in the floor, or it can be hacked with 75 Science.

The western shack has multiple traps, including three frag mines, a rigged shotgun with a tripwire, and two bear traps. Once the traps have been disarmed or avoided, the terminal just needs to be activated and "Reset Mainframe Connection" selected.

This second terminal is protected by several NCR guard dogs, but they aren't much of a problem. Killing them has no impact on NCR reputation. Activate it just like the first, by selecting "Reset Mainframe Connection."

Gehe zum HELIOS-One-Zentralrechner

The player then enters the tower via a door near the base. Just past the door and a short hallway is an area with three hostile turrets and hostile robots. In a room just across from the entrance is an easy locked terminal that controls the turrets. This same room also has four armed land mines.

The player then must wind through the rest of the building, destroying many robots along the way, until arriving at an elevator in the basement that takes the player to the observation level. Along the way is a Poseidon Energy employee ID card. There are two lying on the floor in a room adjacent to the room with the elevator. There is a door in the elevator room with an average lock that leads to the room with the IDs, or the player can go back through a room filled with protectrons(Note: Combat with these protectrons can be avoided as they are contained in shielded charging stations until activated by a laser Trip-wire at the base of the door to the room containing them, Either disarming it (85 Repair or 67 Science skill required) or simply jumping over it will prevent them from becoming hostile.) and down a hall to reach the back door of the room.

Repariere den HELIOS-One-Zentralrechner

The observation level contains not much more than the mainframe itself and stairs to reach the exit door to the outer viewing deck. The mainframe is not working, as it doesn't have enough power because the attached generator is malfunctioning. The player can either repair the generator (which is connected to the mainframe by a steaming hose) with a piece of scrap metal and 35 Repair, or can go up the stairs to find a maintenance bot called PYTHON, which can be activated with a Poseidon Energy employee ID card or with 45 Science skill. Once activated, the robot will repair the mainframe.

Wähle eine Ausgangskonfiguration

The terminal on the mainframe contains some notes the player has probably already seen on previous terminals in the building, and an option Configure Power Grid. Selecting it reveals 5 options:

  1. McCarran and Las Vegas Strip: By directing the extra power toward Camp McCarran and the Strip, the power will be transferred to the NCR home states along with the energy generated at Hoover Dam and part of it to power the neon lights in the casinos in New Vegas. You will gain NCR fame for making this decision.
  2. Fremont and Westside: This solution will direct all the power toward the two poorest areas in the New Vegas area and the Followers of the Apocalypse camps located there. This pleases the Followers of the Apocalypse, though it won't benefit as many people as it potentially could.
  3. Full region: The energy will be distributed to the entire regional grid equally, but as a result everyone will only get a small amount of energy and the plant will suffer frequent brownouts. You will gain a large amount of Followers of the Apocalypse reputation and Ignacio Rivas will give you a Big Book of Science, 3 stimpaks and 2 doctor's bags as a reward for making this decision.
  4. ARCHIMEDES II: This solution diverts power to the next-generation space laser system mentioned in the terminal notes and will give the player the option of calling down space-laser strikes once every twenty four hours (Patch Update), provided the player has also obtained Euclid's C-Finder. The Followers are satisfied with this option, as Ignacio Rivas does not know the location to which the power has been diverted. However, Ignacio will not give you a Big Book of Science as part of your reward.
  5. Full region (emergency output level): This solution overloads the plant, which prevents Archimedes I from being activated (see further notes). This gains no reputation with any faction, as no one will be getting any power, but Ignacio Rivas will still give the player a small reward out of sympathy.

Once one of the five options has been selected, the terminal returns to the main menu. A new option comes up at this point, Arm ARCHIMEDES Plant Defense System. If it is activated, then the Archimedes I plant defense system will be triggered as soon as the player activates the reflector control panel on the outside of the tower. Doing so will call down a laser strike on the area around the plant (unless power option 5 was selected), killing all the NCR personnel in the area. This result will earn you massive infamy gain with the NCR and no rewards from either Fantastic or Ignacio Rivas, even if the power is diverted to their preferred location.

Until the choices are locked in by activating the reflector control panel, the status of the Archimedes I defense system can be changed and the options for where the power goes can be changed.

Zeit den Schalter umzulegen

Once the player has chosen the final power grid disposition and whether to activate Archimedes I, the final step is to go up the stairs and through the door to the outside of the tower. The reflector control panel is down a spiral ramp to the left. It can only be activated between 9 am and 3 pm. Once the player activates the control panel, one of three things will happen:

  • If the player has chosen to activate the Archimedes I defense system, and has chosen option 5 (overload) for the power grid, horns will blare and a warning will play about the imminent weapon test, but shortly thereafter, everything grinds to a halt. If the player is trusted by Ignacio Rivas, they can now go talk to him to receive their reward. Otherwise the quest ends.
  • If the player has chosen to activate the Archimedes I defense system, and has chosen any of options 1-4 for the power grid, the horns blare and warnings sound, and this time everything works perfectly. All of the NCR troops in the area of the plant (inside and out) are obliterated in a massive display of pyrotechnics. The quest ends and the player gains a significant amount of NCR infamy and turn the Brotherhood of Steel hostile to the player. Fantastic and Ignacio Rivas will not have been killed, but will refuse to talk to the player. If the player goes away for two days after this and returns, the plant will be occupied by Caesar's Legion, who have stepped in to fill the void.
  • If the player has not chosen to activate Archimedes I, but has chosen any power grid option, the plant powers up.
    • If the player chose anything other than option 1, and is not trusted by Ignacio Rivas, the quest will end with no reward.
    • If the player selected option 1 (McCarran and the Strip), they can talk to Fantastic, who will be thrilled, claim all the credit, and give the player nothing. The player will gain a lot of NCR reputation.
    • If the player selected option 2 (Freeside and Westside), and is trusted by Ignacio Rivas, they can talk to him to get 3 stimpaks, 2 doctor's bags, and a moderate amount of Followers of the Apocalypse reputation.
    • If the player selected option 3 (Full Region), and is trusted by Ignacio Rivas, they can talk to him to get a Big Book of Science, 3 stimpaks, 2 doctor's bags, and a large amount of Followers of the Apocalypse reputation.
    • If the player selected option 4 (Archimedes II), and is trusted by Ignacio Rivas, they can talk to him to get two stimpaks, a doctor's bag, and a small amount of Followers of the Apocalypse reputation.
    • If the player selected option 5 (Full Region, Emergency Output Level), and is trusted by Ignacio Rivas, they can talk to him to get 3 stimpaks, 2 doctor's bags, and no reputation gain.
  • No matter how the quest ends, the player gains 550, 480 or 350 XP.

  • In order to avoid glitches and bugs, it is a very good idea to wait by the reflector control panel at the top of the tower until the entire powering up sequence is done, whether the player has elected to activate Archimedes I or not. The sequence ends with a bright white light filling the screen (if Archimedes I was not activated) or a large laser beam coming down from the sky, causing a massive explosion (if Archimedes I was activated).
  • If Arcade Gannon is with the player, he will encourage the player to distribute the power over the Freeside and Westside districts of New Vegas, saying the NCR does not need it. With Intelligence 7 the player can convince Arcade that the NCR needs HELIOS One as a backup. He may not say anything if you started the quest before receiving him as a companion. Whatever distribution choice the player makes, he will comment on it. Arming Archimedes I will cause him to get angry and leave permanently.
  • Activating the Archimedes I defense system while having Boone as a companion might cause him to confront the player, and possibly leave or become hostile, depending on the player's current NCR reputation. (This is not special to HELIOS One; he will confront the player if the player's NCR fame/infamy ratio goes below neutral, or if he's warned the player once about hurting the NCR and their reputation gets worse.)
  • If the player did not arm Archimedes I during this quest, they can come back later and arm it, then walk outside and the attack sequence will play (if they didn't choose option 5 the power during the quest), producing the same infamy gain as if they did it during the quest. However, the NCR troops inside the building will not disappear, nor Haggerty and her troops at the front entrance, and all NCR troops in the area will turn hostile.
  • If the player returns after the Legion have taken over (after activating Archimedes I), Ignacio Rivas will be dead and Fantastic will be wearing a Legion uniform. He has a whole new set of dialogue about his belief that Caesar's Legion is the next big thing.
  • Fantastic can be killed without any loss of NCR Reputation.
  • If you have joined the Legion and are vilified by the NCR, you can still complete this quest. Just kill any soldiers you encounter and no NPCs will be hostile.
  • Ignacio heavily mentions code words that will help you complete ED-E My Love.

Hinter den Kulissen

  • The title of this quest is a reference to a 1949 song, "That Lucky Old Sun", by Beasley Smith and Haven Gillespie.
  • The passwords to the Eastern and Western reflector control terminals can be converted from hexadecimal into ASCII, producing the phrases "My voice is my passport" and "Too many secrets." The phrases are originally from the movie Sneakers (1992), starring Robert Redford. They were used as computer passwords in that movie.

  • A number of remaining resources indicate that at one point this quest included a method for completing it on behalf of the Brotherhood of Steel, allowing them to take over the facility. Among other resources, the quest includes greeting dialogue for Brotherhood guards, indicating their satisfaction at gaining control of HELIOS One. Other unused resources include the guards themselves (FormID 00143924) as well as the corresponding dialogue faction for these guards.
