HELIOS One

HELIOS One is a Poseidon Energy concentrated solar power plant that used to, and potentially still can, generate and provide power to the Las Vegas Strip and regional power grid. It also contains the control system for two experimental satellite weapon systems, the self defensive system Archimedes I and the offensive system Archimedes II.

Before the War
Established before the Great War as a next generation solar power plant, hailed as the Dawn of a Golden Age, Helios One was more than just a renewable source of energy. It doubled as a research and development facility for the U.S. Army's top secret orbital energy cannon, Archimedes II. Having joined the "Poseidon Family" when they began work, employees of HELIOS One were expected to keep company projects a secret; carelessly discussing developments could pose a threat to national security if the communists got wind of Poseidon projects. The military side of affairs was handled by Brigadier General Scott Lowe, who oversaw the testing of the weapon on site. Tests of the orbital weapon proved to be less than successful, as while both the orbital cannon (Archimedes II) and the array of smaller lasers dedicated to facility defense (Archimedes I) were successful, they resulted in a 2.5 minute downtime at the facility and system-frying power fluctuations in nearby installations, including Hidden Valley and Black Mountain. Further development was precluded by the destruction brought by the Great War.

Operation: Sunburst
After centuries of disuse, the Brotherhood of Steel discovered the facility. The occupation of HELIOS One was a decision made by Elder Elijah, who intended to unlock the secrets of the power plant. The Mojave chapter operated freely amid the Vegas wastes for several years, carrying out many reclamation missions without serious opposition.Fallout: New Vegas Official Game Guide Collector's Edition p.43: "Brotherhood of Steel The Brotherhood of Steel is a militant organization devoted to the preservation of pre-war technology and human knowledge. Their professed mission is to preserve pre-war technology and human knowledge for the benefit of future generations. In practice, its definition of technology is strangely selective, ignoring basic but potentially useful technologies (genetic modification of crops and civil engineering, for example) in favor of combat technology such as energy weapons and power armor: and even now, nearly two centuries after the Great War, the Brotherhood zealously restricts the use and knowledge of such technologies to its own membership. ''The Mojave Brotherhood operated freely amid the Vegas wastes for several years, carrying out many reclamation missions without serious opposition. The balance of power shifted in 2251, when a large contingent of NCR troops entered the region and occupied Hoover Dam. Conflict was inevitable. Nearly two years of guerrilla skirmishes culminated in a pitched battle at HELIOS One, a solar energy plant the Brotherhood had been refurbishing for several months with the goals of bringing it back online and activating its hidden offensive capabilities (the ARCHIMEDES II death ray). The battle for HELIOS One (Operation: Sunburst) proved a disaster for the Mojave Brotherhood. More than half its Paladins and Knights were killed. The chapter's leader, Elder Elijah, disappeared without a trace. The Brotherhood was driven from the facility, which suffered extensive damage. Survivors retreated to Hidden Valley. Since that defeat, the chapter's leader, Elder McNamara, has restricted activity outside the bunker to occasional reconnaissance missions and high-value raids. All operations take place at night, and engagement of NCR forces is strictly forbidden. Though the Brotherhood's ascetic lifestyle has prepared its members for a sequestered existence better than most, the passivity of their current situation has proved highly stressful."'' (Fallout: New Vegas Official Game Guide faction profiles) In 2274, the NCR had officially set up a base at McCarran International Airport. From there, the NCR soon set its sights on the HELIOS One solar plant. Elijah, still believing that the plant contained an unprecedented military advantage, refused to leave the plant, and forced the Paladins to continue defending it. Two years of guerilla fighting against the NCR followed, culminating in Operation: Sunburst in 2276.

The NCR launched the operation to capture HELIOS One. Outnumbered by NCR soldiers, a pitched battle took place. Despite the Brotherhood being in control of far superior equipment, such as energy weapons and power armor, the Brotherhood had no reinforcements, and were gradually worn down by NCR's attacks. By the time the retreat signal was given by Paladin McNamara, more than half the chapter lay dead in the dust. The chapter's leader, Elder Elijah, disappeared without a trace. Brotherhood survivors retreated to Hidden Valley, while the NCR regrouped at the newly occupied HELIOS. When they finally set out to locate and destroy remaining Brotherhood forces, they were nowhere to be found.

Under NCR control
As NCR soldiers scouted the interior of the plant, they discovered that the Brotherhood had left them with one last nasty and spiteful goodbye in the solar collection tower before departing. The building's automated defense system had been activated, and the halls and corridors were now crawling with active and heavy armed security robots and turrets, meaning that the getting at the innards of the building was extremely dangerous. Not being willing to divert manpower and resources towards such a hazardous undertaking and with no way of remotely shutting down the security system, the NCR command instead ordered the tower to be on lock-down, and had it secured in way that required permission from two separate security terminals before it could be entered.

The NCR established a firm foothold in HELIOS One and its vicinity, although due to a stroke of bad luck, an incompetent con artist was hired to act as the facility's principal engineer. He was unable to bring the facility to even moderate operational status, leaving it stuck at 1% efficiency. Ignacio Rivas was posted by the Followers of the Apocalypse to research the facility independently and ensure that the ignoramus hired by the NCR would not figure out a way to unlock the facility's dark secrets.

HELIOS One power plant
At the beginning of the events of Fallout: New Vegas the facility is controlled by the NCR, who have a detachment guarding the facility. At the front entrance is Lt. Haggerty, who must be convinced to allow the Courier in, or the player can lockpick a side door to gain entrance. Another way to enter through the front entrance is to use a Stealth Boy and sneak inside.

Downstairs, the building's hallways circle in on themselves, leading to a pool room, where a unique toolbox that spawns either a sawed-off shotgun or a 10mm pistol can be found on a nearby shelf, as well as an open workshop leading upstairs, to the opposite side of the downstairs area, as well as a door leading further back into the building.

Traveling further back into the building is a "technician," Fantastic, who is working on getting the power plant functioning; the room adjacent to Fantastic's contains a scientist, Ignacio Rivas. A nearby door leads to the mirror yard.

Mirror yard
Behind the main building is the solar collection tower and an array of computer-controlled mirrors. There are also two mirror control terminals in small shacks, and several tents set up by the NCR troopers guarding the facility. The western terminal is guarded by mines, bear traps, and a rigged shotgun, while the eastern terminal is guarded by NCR attack dogs. There are also a number of broken solar panels scattered around, that you can optionally repair/salvage for the Sunshine Boogie quest: you'll find the first near the tents behind the western terminal; walking along the outer row and the fence towards the eastern terminal will produce the next three; the final one is by the tents near the eastern terminal.

Solar collection tower
Inside the solar collection tower, past a small straight path there are three hostile automated turrets and several (level-dependent) security robots, a mix of protectrons, robobrains, Mister Gutsies, and/or sentry bots. Going straight ahead leads to an unlocked door to a small room containing several frag mines (both active and inactive) and an easy locked terminal. The terminal can be hacked to shut off the turrets or get them to fire indiscriminately at all targets (including the security robots). Near the entrance is a water fountain with no radiation. Downstairs is a small room with two pulse grenades on a shelf, and an average safe containing more pulse grenades and pulse mines plus miscellaneous loot.

The level continues through a double-wide door and down a sloping corridor guarded by a leveled security bot. The door at the bottom leads into another narrow corridor, leading to another multi-level room with stairways and catwalks, guarded by a Mister Gutsy.

At the bottom of the catwalks past the Mister Gutsy is a door leading to a corridor that branches left and a shorter one to the right ending at a door. The corridor to the left contains a single protectron in a shielded charging station, past which is a laser tripwired door (disarm with an 85 Repair or 67 Science skill). The room beyond contains four more protectrons also in shielded charging stations. The tripwire releases the shields and activates all five robots. The door to the right in the initial corridor opens into a room contains some desks, skeletons and two Poseidon Energy employee ID cards. Both paths have doors that adjoin the final room; which has an elevator that leads to the observation level of the tower.

HELIOS One observation level
The observation level contains the mainframe computer used to activate the plant and direct its power, plus a broken generator that can provide power to the mainframe and a repair robot called PYTHON. See That Lucky Old Sun for more about repairing and using the mainframe. There is a door at the top level that leads to the observation deck. A desk by the generator has a wooden box with embossed red symbols([!]-[X]-[H]-[A]-[H]-[X]-[@]) on it. It cannot be picked up but may be interacted with.

Observation deck
This is a circular deck all around the top of the solar collection tower. A spiral catwalk leads down from the entrance door. There is a reflector control panel that must be activated to complete the retargeting of the mirrors during That Lucky Old Sun. This location is outside, so the player can fast travel from here, though it is not recommended to do so during the HELIOS One/Archimedes I startup sequence, as this can cause quest glitches.

Notable loot

 * D.C. Journal of Internal Medicine upstairs in the main building, lying on a bed in the same room with the Eastern reflector control terminal password (head to the right from main entrance, through the pool room, and right up the stairs).
 * Big Book of Science can be acquired from Ignacio Rivas during the That Lucky Old Sun quest if the Courier chooses to distribute the energy to the full region along with a large amount of Followers of the Apocalypse reputation.
 * Poseidon Energy employee ID card - in the solar collection tower, on the bottom floor, in the room just prior to the elevator. It is on the floor next to a skeleton in the corner.

Appearances
HELIOS One appears only in Fallout: New Vegas and is mentioned in Dead Money.

Behind the scenes

 * In Greek mythology, Helios was the Titan personification for the sun and in Greek (Ἥλιος) the word still translates to "sun."
 * This structure appears to be modeled after Solar Two located in the Mojave Desert in California, but the location is more similar to the unrelated Nevada Solar One southwest of Boulder City, Nevada (though Helios One is a bit further north; Nevada Solar One is just southwest of where Novac would be if it existed in our world).

Bugs

 * The NCR will be hostile towards the Courier, even if he/she is idolized by them.
 * Protectrons within the room with the laser tripwire seem to be immune to explosive damage.
 * Disarming the laser trip wire within the room with protectrons with Science skill does not however prevent it from opening the forcefields and letting protectrons out to attack Courier.
 * The hostile protectrons in the blue glowing holding containers can be disabled with Robotics Expert while inside the container. Somewhere between the waist and the feet, the cursor will typically change to red and you can "activate" the protectron and receive the option to disable it, as usual with the Robotics Expert perk.
 * The southwest room with the Mister Gutsy has two filing cabinets occupying the same place next to the sink.
 * When entering the area with the solar panel, the Courier may be attacked by a few of Old Lady Gibson's dogs (Including Rey, Colmillo, Basura, and Audaz.) and a couple of mole rats. It is also possible to witness Old Lady Gibson appear along with her dogs. Reverting to previous auto save will prevent this, but reverting to a save (not auto) will make this occur. It is also possible to be attacked by just mole rats. It is also possible to obtain the Big Boomer Shotgun, from killing Old Lady Gibson
 * At HELIOS One, Old Lady Gibson's dogs may spawn at the back door (facing the tower) and become hostile.
 * Also seen once where dogs were not hostile, but Gibson was sitting in mid-air. Also, upon exiting Helios One there were sounds of metal objects colliding with one another. Upon looking to the ground the cursor displayed info on multiple junk items (such as paint guns and tin cans). However, these items were invisible.
