"Second Chance"
Welcome to REPCONN Headquarters, Rocketeer! Come all this way to see our little facility, have you?Tour guide

REPCONN headquarters is a location in the Mojave Wasteland in 2281. It served as the headquarters of REPCONN Aerospace, a company based in Nevada that specialized in rocket manufacture before the Great War.


REPCONN headquarters was the home office of REPCONN Aerospace (Rocket Engineering and Production COmpaNy of Nevada), located in Henderson.[Non-canon 1][Non-canon 2]

After the company was acquired by RobCo Industries in 2075, the building was overhauled, providing greatly increased security, so that they would be able to handle classified research. The security took the form of automatic facial recognition monitors, badge scanners, security locks and heavily armed sentry bots for defense. All employees were required to wear identification badges at all times, lest they be harmed by the security system.[1] The third floor was marked executives only, with the employees requiring a daily password to gain access.[2]

No amount of automated security could replace humans, however. A mole was delivering information on REPCONN's plasma rifle project undertaken at the headquarters to Poseidon Energy, their competitor. Although the fact was detected by the company's information services, no concrete evidence could be located to take official action against such industrial espionage.[3] REPCONN itself was guilty of industrial espionage, as their plasma rifle project relied in its final stages on Project SEMELE schematics acquired from Poseidon Energy.[4]

The project eventually produced the first working prototype, the Q-35 matter modulator. Poseidon Energy's mole, Julia Masters, was tasked with intercepting the prototype on its way to the Department of Defense. The weapon was never delivered, as its delivery was interrupted by the Great War.[5] The building was left abandoned for decades, haunted by its automated, self-maintaining security systems forever on watch for trespassers. The centuries were not kind, leading to structural damage in the building's shell, but not the electrical system and computers.


Outside the building, there are three friendly maintenance robots. The interior of the building contains many hacking and lockpicking tasks. The main purpose of lockpicking and science in this location is to obtain security clearance so that the many defensive sentry bots do not become hostile. There are several safes as well, most of which can be opened with either Science or Lockpick skill. The hardest of which are two Very Hard locked terminals and one Very Hard locked door. The first Very Hard locked door and Very Hard locked terminal can be bypassed by progressing through the entire building carefully. Behind them lies the unique weapon, the Q-35 matter modulator.

First (main) floor

Upon entering the building, the Courier will find 3-5 Fiend corpses and a number of maintenance robots. The area has several locked doors and safes. The most notable is the Very Hard locked door that leads to the unique plasma rifle, the Q-35 matter modulator. This weapon can also be obtained via the second level through another locked door, however, this is only a Hard lock and not a Very Hard lock. There is a tour guide REPCONN robot that will greet the player character upon entering the facility. It will tell the player character to return between the hours of 10 AM and 5 PM (if it is not any time between then).

If the Courier chooses to wait, they will get to take a free tour, avoiding all lockpicking that is needed to get to the utility room located in the orrery where they will find Jenny Millet's security keycard. Along with the keycard, the player character can use the facial recognition database computer in the room behind the locked door the Fiend corpses are in front of, to bypass the security robots. The door can be unlocked by lockpicking or cracking the security terminal (both Average difficulty).

There are 12 hidden doors throughout the building (starting at the tour bot), which require 8 Perception in order to detect and 65 Repair to jam them closed. Jamming all of the doors closed is worth 540 XP (45 XP each).

  • Hidden door 1: The first door in the building is to the left of the bathroom door and the doors leading to the exhibits.
  • Hidden door 2: Along the left wall of the second exhibit room (rocket room).
  • Hidden door 3: Through the first door on the right after entering the building (Average lock), then to the left of the regular door at the other end of the room.
  • Hidden door 4: Go through the regular door next to the previous hidden one, it's at the end of the hallway through the Very Hard locked door. Right beside the chamber that holds the Q-35 matter modulator.
  • Second floor access: For the purposes of this guide, use the stairs, not the collapsed ceiling behind the Very Hard locked door.

Second floor

Access to the second floor is gained by passing a 7 Intelligence challenge at one of the mobile facial recognition scanners. There is an option of using a Very Easy locked computer on this floor to add facial data to the database.

A second floor security card can be found in one of the rooms on this floor. It is in the same room as the terminal where the third-floor executive pass can be printed. This is required to get past the maintenance robots who will request the floor be vacated, even if visiting between the hours of 10 AM and 5 PM. There is a door that leads to a room "REPCONN Office Main Floor" that requires a keycard to access. Inside there is a hole in the floor that will lead to the unique Q-35 matter modulator plasma rifle, bypassing the Very Hard locked door and terminal.

There is a Hard locked terminal on this floor which can be used to print out a pass that allows safe passage on the top floor. To the left of this terminal, along the back wall, is a first aid box that may be invisible to the player character unless directly facing it.

  • Hidden door 5: Directly to the right of the security poster when entering from the stairs to the first floor.
  • Hidden door 6: Right of the facial recognition terminal, left of the regular door out of the room. To find the terminal on this floor, go left and through the bathroom when coming up the stairs mentioned above.
  • Hidden door 7: When using the regular door next to the previous hidden one, head straight to the end of the hall, go right through the broken wall. The hidden door is to the left of the well preserved corporate espionage poster.
  • Hidden door 8: From the previous hidden door, go out the regular door on the other side of the poster, turn right and then take the first left. At the intersection, turn left, and the door is along the left wall here.
  • Hidden door 9: From the last door, enter the small office on the right (the one without a collapsed ceiling), the southwest cubicle in the room has the final hidden door on the wall behind the chair.
  • Third floor access: Use the office opposite this last door and the ceiling ramp to reach the third floor.

Third floor

In order to remain protected from the robots, a 7 or higher Luck or an Intelligence of 2 or less is required, which allows the player character to guess the password, which is "ice cream." Giving the correct password once is all that is required. A REPCONN third floor security card in Piers Isley's briefcase can be found close to two dead Brotherhood of Steel paladins near the main entrance to the third floor. In the room with an Average lock on the second floor (across the hall from the locked entrance to the main floor) is another terminal with an encrypted message on it. This contains the password to Isley's terminal on the third floor, which would otherwise need to be hacked. It is possible to destroy the mobile facial recognition scanners and sneak, but risks the release of sentry bots.

Robots can be disabled on one of the executive computers. In doing so, the maintenance and scanner bots can be destroyed. Also, the alarms will not sound. If one destroys the first scanner robot encountered before it engages in dialogue, the alarms will not go off and no other robots on the floor will interact with the Courier.

This location is one of the focal points of Still in the Dark, a quest for the Brotherhood of Steel, to find their missing patrol. The missing patrol can be found dead on the third floor, their T-51b power armor and laser rifles can be taken. Nearby lies a skeleton and Piers Isley's briefcase, containing 200 pre-War money and a REPCONN third floor security card allowing third-floor access without harassment from robots, as well as access to the Very Hard locked door (on the first floor) to the Q-35 Matter Modulator.

  • Hidden door 10: Use the door on the right when first appearing on the floor, the hidden door is along the right wall in the bathroom.
  • Hidden door 11: Turn around and head down through the bathroom, step through the hole in the wall and it's along the right wall.
  • Hidden door 12: When exiting through the large double doors in the room you entered for the last door, turn right and head through the open doorway, turn left and head to the end of the hall. In this room head through the hole in the wall, turn left and the final door in the building is between the file cabinet and bookshelf.

Tour messages

Header Message
"Boring Old Rod? Or..."

What's this? A dull rod? Not so, Rocketeers! This "dull rod" once powered REPCONN's old nuclear-propelled rockets and still contains harmless* traces of radioactive material. As an exercise, stare closely* at the rod and try to spot the telltale glow!

* While this case is lead-lined (standard in these cases, not specifically requested for this display), do not touch, look, or stand too close to this exhibit - keep your legs moving and see the rest of the museum!

"Plas-Ma What?"

Hold up, Rocketeers, what's this? This trio of cylinders isn't a trio of cylinders at all!* They're containers holding what some* scientists call "plasma." Can you say "plasma?" REPCONN's always looking to the future, and in our future, we don't have to worry about radiation, health risks, or lawsuits when using this new and improved fuel source to blast our rockets into and out of the sky!

* Clarification: "Cylinders" and "plasma" are factually correct designations of display items, both by definition and by the scientific community.

"Radioactive Waste?"

We've all heard "stories" that radiation is dangerous - fact or fiction?* A common site in factories, military installations, and the basements of selected government-funded middle schools, these safety barrels* are just what the name implies - safe. While their attractive coloring can be interpreted as a warning, for REPCONN, it's an invitation to a future filled with nuclear power!

* Rhetorical questions and nomenclature of exhibit items cannot be used as a basis for criminal prosecution.

"Nuclear Family!"

Why, look here! A pile of itty-bity safety barrels,* all nestled together like a family sitting down to dinner! Now, while it's claimed even the safest nuclear waste disposal procedures seep poison into the environment that never, ever goes away, in REPCONN's case, we say it all depends on where you put them - and Nevada's just the place!

* Nomenclature for "hazardous waste barrels" as per REPCONN glossary specs.

"Ready, Set, Launch!"

Force your parents a short drive south, and you'll see the retractable dome of REPCONN's launch facility (not actual size!). You may have heard wild stories about rocket flights and their impact* on nearby towns and communities, but REPCONN feels you can't put a price of space exploration - after all, Rocketeers, you do want to go into space someday... don't you?

* Statement is figurative and inadmissible as evidence in a court of law.

"Rockets Away!"

Just like the rocket you see here, we're aimed at the sky, but we've got a ceiling in the way! See, Rocketeers, while REPCONN is (was) focused on non-radioactive* propulsion engines, we still need to sneak back and use some of our older "proven" techniques with nuclear-driven engines to make space travel a reality. Partnered with our new buddy RobCo, we've dug up older, cheaper technology for upcoming orbital projects. No worries, even if you can't always see what we're up to up there - we can see you!

* Any implication of radioactive material as negative is unintentional and in no way reflects RobCo or its subsidiary REPCONN.


This sleek and purple R77-293A "Needlenose" is what happens when you mix fossil and plasma in a rocket and shake it up! The fossil fuels punch this sharp-nosed terror through the sky, and the plasma is used to shoot it through space to planets where REPCONN can mine more fossil fuels,* continuing the whole cycle again!

*Interplanetary mining and resource rights still in negotiation.

"Big Fat Fiery Fred"

V29-321G may look like a big, fat, red rocket, Rocketeers, but Ol' Fatty here ran circles around the Earth not so long ago, so let's see you keep up! Sure, V29-321G's re-entry gave it its more commonly-known nickname "Big Fat Fiery Fred," but here at REPCONN we chose to focus on the successes and apply what we learned about explosive-resistant shielding to future models and even our landing platforms!*

*The newly-(re)constructed REPCONN Launch Facility was a direct beneficiary of this discovery.

"Green Bean"

Officially called the "Z43-521P" by silly engineers, we prefer to call this little scrapper by its true nickname, the "Green Bean." After all, which would you prefer in your backyard garden - a smoldering Z43-521P, or a green bean?* One sounds like it belongs if mentioned on the news, and make news it did... featuring REPCONN's plasma engine, it was soooo newsworthy that we decided to take the Quantum Matter Modulation unit out and see if we could use it for non-explosive uses.

*Rocket nickname chosen after results of first trial landing.

"Watch Your Step!"

Whoa, watch your step! You don't want to be facing this fearsome fellow if you accidentally stumble into a restricted area. Whether sporting the latest in dual miniguns, rockets, or laser cannons, the Sentrybot not only takes it job seriously, it also takes no prisoners! It's proof of RobCo's commitment to defense that these deadly guards are concealed in chambers throughout this facility, so let this be a warning: Watch where you step, or out'll come RobCo, guns blazing!

Exhibit Brought to You By Your Friends at RobCo

"The 'I' in 'Eyebot.'"

RobCo's always had an eye for robotics, and this little fellow is no different! This robotic marvel can not only recognize your face and voice with advanced facial and auditory recognition technology, it can also broadcast video and audio as well! Think of it - all the sights and sounds of your radio and TV in your living room at home blasted directly at you on the street, subway, bathroom, or wherever you may be! Never fear, you'll never miss a news bulletin or presidential address again, no matter where you are!

"The 'Hand' in 'Handy'"

You never can have too many hands - three, why not four? That was RobCo's inspiration behind the popular (and cost-effective) Mr. Handy model, the first of the line shown here. Always a help around the household, whether with Mom in the kitchen using its titanium circular power saw or in the garage with Dad using its armor-piercing laser array, Mr. Handy is not just helpful... he's your friend, too.

Exhibit Brought to You By Your Friends at RobCo

"It's Got Wheels!"

Some folks have asked - why not a Protectron with wheels? RobCo wasn't afraid to answer that question: The Protect-O-Bot is the answer. While safety standards prevented this free-wheeling dynamo from entering mass market production despite RobCo's best intentions and teams of lawyers, we take consolation in letting you can see this extremely well-funded experiment as it was intended - a robot moving so fast it looks like it's standing still!

Exhibit Brought to You By Your Friends at RobCo

"Our Rich, Rich Solar System."

A model of our solar system (not actual size). Beautiful, isn't it? RobCo, with its subsidiary REPCONN, has often gazed into the night sky, seeing the rich pageant of stars and planets above us. Our goal? To send unmanned rockets to these other systems, seeing their beauty firsthand while mining ever deeper into each planet's surface for precious resources needed here at home. This is our promise to mankind, extending our reach into a future where the number of RobCo and REPCONN rockets match the stars in the sky.

Notable loot

Second floor map

Top floor map

  • The Q-35 matter modulator - A unique plasma rifle, levitating in an orange cylinder that lies behind a Very Hard locked door on the first floor, near the shipping sign. The Very Hard terminal outside this door also unlocks the door, as does a keycard that's found on the third floor. This room can also be accessed via the Hard locked door marked as "Door to REPCONN Office Main Floor" on the second floor and dropping down through the broken floor.
  • Two copies of Nikola Tesla and You - One is on top of the safe in the same room as the Q-35 matter modulator. The other is on the second floor, next to a Very Easy locked terminal on a desk.
  • Big Book of Science, two Nuka-Cola Victorys and two Nuka-Cola Quartz - On a table in the gift shop, through the Hard locked double doors to the left of the main entrance.
  • Jenny Millet's security keycard - On the main floor, in the utility room past the Solar System display.
  • Five Sunset Sarsaparilla star bottle caps - One located on the first floor in between two bottles on a desk behind the security terminal, one in the gift shop, one in a room with four desks on the second floor (with the red keycard), one on the third floor in the room with the large semi-circular desk on the floor near the shelf with the empty bottles on it (Piers Isley's office), and one in the northeast most room of the third floor, on the desk with the Very Hard terminal (Leonard Steeple's office).
  • Matter modulator project - A holotape relating to the Q-35 matter modulator.
  • 200 pre-War money - On the top floor in Piers Isley's briefcase.
  • 580 microfusion cells - In the office main floor (storage room to the right of the entrance, a desk in the same area and further down in the shipping room).

  • There is an unlocked door leading south from the Solar System display. Up the stairs, Jenny Millet's security keycard can be found on a console by a skeleton. The card unlocks the door on the right as soon as the player enters the building. It also allows one to pass the mobile facial recognition scanner security check (greeting the Courier as Mrs. Millet). It makes the same sound as caps when picked up.
  • Before or during the tour by the tour guide, the robot can be asked about the history of REPCONN. When asked, he will talk about how the company was purchased by RobCo in late 2076, but when asked about RobCo he will say RobCo purchased the company in 2075.
  • Behind the Hard locked door in the gift shop, there are two locked safes almost perfectly overlapping, making it difficult to loot both.
  • No alarm is activated if the mobile facial recognition scanners are killed before they start a conversation with the player character.
  • There are three downscaled radioactive waste barrels in the gift shop, appearing smaller than regular barrels.
  • If Arcade Gannon is an active companion when entering the building, he will discuss some of what he knows of REPCONN's history with the Courier.
  • The Solar System model does not display any moons, nor does it display Pluto.
  • One of the possible endings for the X-13 research facility involves it taking control of the REPCONN headquarters.


REPCONN headquarters appears only in Fallout: New Vegas.

Behind the scenes

When the dialogue check on the second floor is passed (with Intelligence 7), the code given to the mobile facial recognition scanner is "09 F9 11 02 9D 74 E3 5B." This is a reference to the AACS encryption key controversy.

  1. Fallout: New Vegas Official Game Guide Collector's Edition pp. 320-323: "[2.35] REPCONN Headquarters
    REPCONN Corporation was an up-and-coming regional aerospace firm, and keen contributor to Las Vegas political campaigns. They operated a test facility in the Black Mountains to the south (much to the chagrin of the local populations, who long complained of the "REPCONN bombs" landing in their fields and destroying property). The company was purchased by the giant RobCo Company just before the Great War, in a hostile takeover. New security countermeasures were installed, and more militaristic plans were undertaken, especially after the discovery of a special radioactive igniting agent that interested certain senior RobCo members. These countermeasures are still in effect, so investigate this building with caution."

However, within the facility, there's a prolonged stalemate going on between a band of Nightkin, devolved from Marcus' forces up at Jacobstown [1.10] and lead by a deranged man-mountain named Davidson.
