Corruption. Corruption never changes.

In the Fallout universe, in the years before the bombs dropped, it was common knowledge that society was on the verge of collapse. It seemed inevitable. International tensions were so bad that nuclear war was a part of regular conversation in the general public. But within the U.S., there was one specific group that stoked the flames domestically. This group had the most to gain from increasing paranoia, a sense of doom, and a desperate military. They could sell the idea of hope and progress and become multi-trillion-dollar industries. They were scientific researchers and CEOs. They were warriors against ethics. They were corporate America.

Fallout is rich with iconic retrofuturistic symbols that are immediately recognizable and beloved by fans, like the visually striking brands Nuka-Cola and Vault-Tec. But don’t let the smiling faces of Vault Boy or Nuka-Girl fool you; there is always a dark side. The one thing that unites every company, lab, and institute in the wasteland is corruption.

So let’s put on our press caps, channel our investigative companion Piper Wright, and uncover the truth.

• Vault-Tec Corporation
• RobCo Industries
• West-Tek Corporation
• Big MT
• Pulowski Preservation Services
• HalluciGen, Incorporated
• Poseidon Energy
• Nuka-Cola Corporation
• Abraxodyne Chemical

Vault-Tec Corporation

“Vault-Tec is the largest company in America. There’s a lot of money in selling the end of the world.” — Kate Williams, Fallout series

To the public, Vault-Tec sold the very survival of humanity, even if the worst should happen. Their marketing worked. The interiors of the Vaults were designed to look like an ideal suburban American neighborhood, so just sign your name on the dotted line and when the bombs come, it’ll be like your lives never changed. Then, when the surface is safe again, the Earth will be yours to inherit.

In private, the Vaults assumed their intended purpose as centers of human experimentation. Only 17 of the 122 known Vaults worked as publicly advertised. The rest housed thousands of vulnerable people, all hoping to survive disaster, but ended up becoming guinea pigs in the name of human progress — just not progress for these specific humans to enjoy.

But the web of sinister dealings doesn’t stop there for Vault-Tec. Rumor has it, the organization that started the whole thing is an authoritarian shadow government. But their most lucrative partnership was with RobCo Industries.

RobCo Industries

“I’m excited to announce that RobCo has agreed to my proposal to preserve the entire research team’s collective intelligence through the Encephalon Extraction Program. You will each have your cranial cavity scooped out, and your brains suspended in a biomedical solution that will keep your cognitive functions intact and ready to be used for several lifetimes.” — Immobile Weapon Platform Research terminal, Fallout 76

Along with Vault-Tec, RobCo is one of the first companies to appear in the Fallout franchise. In the first game of the series, they are introduced as the inventors of the personal information processor, or the Pip-Boy, that Vault dwellers don on their arms across the country. This was widely considered the greatest joint-venture of all time.

Also among their remarkable technological inventions are the eyebots, protectrons, and sentry bots. But if you asked the common working man, “remarkable” was not the word that came to mind when those robots came to take their jobs.

The owner of RobCo, Robert House, pushed his robots into the workforce, causing mass unemployment across the country. Though this understandably resulted in strikes and riots and even some minor opposition in the Senate, there’s no evidence of any slowing down. In fact, the Appalachian government promised full automation in the region by the year 2087.

Robert House remained a prominent, sinister figure pre- and post-war, even driving his own half-brother and owner of H&H Tools Company, Anthony House, mad with fear and paranoia. As of Fallout: New Vegas as well as the second season of the TV series, Mr. House resides in New Vegas, surrounded by an army of RobCo securitrons, scheming his way through the post-apocalyptic hellscape.

West-Tek Corporation

“In business news, West-Tek stocks are up again amid reports their latest biological products will revolutionize skincare.” — Radio ad, Fallout series

West-Tek specialized in defense and research. Before the bombs, they were most well-known as the creators of the T-45d Power Armor and, later, the T-51 Power Armor. Though the T-45d Power Armor was effective during the invasion of Alaska, the armor had serious design flaws that were to blame for many needless deaths. As West-Tek had gained much power and influence by that point, they felt little pressure to stand and take responsibility for their negligence.

Contracted to design immunizations for a plague and bioweapons, the side effects of that project caused them to shift gears and start testing what they called the Forced Evolutionary Virus, or FEV, which caused massive growth and completely changes the genotype and phenotype of organic subjects.

To test drive the FEV on a larger scale than what can be produced in a lab, West-Tek put the virus in Huntersville’s water supply. The town then became the birthplace of the Appalachian race of super mutants. And to top off their participation in making the wasteland even more of a horror show, they created and released a few “cryptids,” terrifying mutants that resembled creatures of folklore, like the snallygaster and the Grafton monster.

Big MT

“Yes, Project: Burke involves what some less science-minded individuals might call ‘grave robbing.’ Yes, we’re forced into this due to budget cuts. No, none of the senior staff uses the bodies for anything else.” — Dr. Adam Figgis, Fallout: New Vegas: Old World Blues

Like many of these companies, Big MT received funding by talking big about their concern for the future of humanity. Research was their focus — the kind that couldn’t have them bothered with moral limitations. Their experiments sourced unwilling participants from places like their own concentration camp, thanks to their partnership with the U.S. Army, then from exhuming corpses and assassinating non-political targets for new research specimen.

Located in the Southwest, the Big MT Research Facility created many of the deadly creatures seen throughout Fallout: New Vegas such as the cazadors and night stalkers. They also sent the very plant sample to Vault 22 that was ultimately responsible for the Vault’s green undoing, turning their scientists into violent spore carriers.

Pulowski Preservation Services

“Unlike those other guys (Vault-Tec), the sensible folks in Pulowski Preservation Services have created an affordable line of personal protection products to make sure no one gets left behind. Personal protection there when you actually need it. … Exact change only.” – Those Other Guys, Fallout 3 advert

What if you could buy your survival on a budget? Pulowski Preservation Services answers the need for more affordable options to live through the end of the world with a self-preservation pod that’s not much bigger than a changing room. Only, if you step into the pod and miraculously survive the blast from the nuclear bombs, which the pods are not equipped to withstand, then you’ll soon discover that you are without food and water and will perish in a few days regardless.

In spite of them blatantly selling a product that doesn’t work, they profited from desperation and Pulowski Preservation shelters were installed in urban areas all over the country including Appalachia, the Capital Wasteland, and the Commonwealth.

HalluciGen, Incorporated

“Adjust dosage, retest. At least this is making progress. If marketing would just position this as a military-grade chemical weapon, we’d be done here. Would make a good grenade or artillery shell.” — Development Lab Manager, Fallout 4

HalluciGen was a biochemical manufacturer based in Boston. It primarily developed technology for crowd control, especially for use in the automation riots against RobCo. However, most of their products failed in testing. Their HQ is a labyrinth of rooms for experimentation, complete with an observation room to overlook the tests as the products misfire in hilariously dark ways. One product called the Irradicator was originally intended to be a field decontamination system. In practice, it worked by applying extremely lethal doses of radiation.

HalluciGen’s most popular product was HalluciGen Gas, which was a tool in the form of a grenade. It caused massive damage to a person’s adrenal glands, making them go mad and aggressive. One such company employed the use of the gas with some … mixed results.

Poseidon Energy

“To whoever hears this: I was just following orders. Check my terminal. It’s all there. This whole fiasco, it goes all the way to the top. Poseidon. The military. The government. They were all in on it.” — Poseidon security director’s recording, Fallout: 76

The energy conglomerate faced some riots of their own, particularly against a miner’s union due to the company’s distaste of organized labor. They used HalluciGen’s riot control gas, which caused the peaceful strikers to suddenly grow aggressive and attack each other. While it might’ve been written off as a win since the union’s image was irreparably tarnished, the gassed strikers stormed and took control of the Poseidon Energy Plant.

Poseidon Energy had an extended reach, though they weren’t as successful in weapons manufacturing as they would’ve liked when their own spin on plasma weapons was stolen by REPCONN, a subsidiary of RobCo. However, they played a major role in the survival of the Enclave, a deep state fascist government and self-proclaimed successor of the pre-War United States. Publicly, the oil rig was just a deep-sea drilling platform constructed by Poseidon Energy. In secret, it was a base for the president and his cabinet to survive the inevitable nuclear war.

Nuka-Cola Corporation

“Absolutely loved the ‘Nuka Condolences’ Fruit and Cheese Baskets you sent out to the families of our early prototype Quantum flavor testers. Great idea.” — John-Caleb Bradberton, Fallout 4: Nuka-World

One might expect that the corruption of a soda company might be a far cry from the likes of the previously mentioned robotics, biomedical, and tech giants, but the inventor of Nuka-Cola, John-Caleb Bradberton, had an arsenal of the world’s top organic chemists at his disposal. That, plus his overwhelming success in the market — due in part to buying out the flavor patents of his competitors — attracted the attention of the U.S. military. And so, the soft drink company was contracted to create chemical weapons.

Nuka-Cola’s Beverageers (chemical engineers on Bradberton’s team) developed a protective coating for Power Armor and explosive munitions using a brand-new isotope called strontium-90. Naturally, Bradberton next asked the question: Can he make this the first isotope safe for human consumption?

Testing resulted in over 60 fatalities, and caused radiation burns in many more. Eventually though, they succeeded, and the drink with the signature glow was called Nuka-Cola Quantum.

Bradberton’s compensation took the form of a top-secret government project called the LEAP-X program, which boasted the tech to be able to extend one’s life indefinitely. With the end of the world on the horizon, the offer was irresistible. So in the bowels of his theme park, he built a private Vault. With the Nuka-World expansion for Fallout 4, the Sole Survivor can visit this Vault and find Bradberton’s talking head in a jar surrounded by Nuka-Cola memorabilia.

Abraxodyne Chemical

“I hear your concerns, I do, but think of it this way: If we get this right, then Abraxodyne Chemical will be helping protect our troops overseas. This stuff is so strong, it could be used as a deterrent against the Commies! Who knows, it might even prevent a war. Now that’s patriotic!” — Abraxodyne tape 11, Fallout 76

Thanks to the giant region expansion in Fallout 76 released on December 2, Abraxodyne Chemical can confidently be added to the list. Along with the addition of Burning Springs, a portion of Ohio that’s now a vast desert, there’s a new questline that’s dedicated to uncovering the nature of the company and its role in the illness the locals call Rust.

Through a series of holotapes, it’s revealed that Abraxodyne was contracted by the military to create a chemical weapon, one that the company called Meadow Breeze. The reddish orange chemical that the weapon fires can be found all over the landscape, leaking out of barrels and turned over Abraxodyne trucks. With the violent sandstorms of the region, these chemicals get kicked up into the air and into the lungs of Burning Springs residents, causing great pulmonary distress and even death.

Though select employees balked at the idea of their family-friendly brand taking on a project in weapons development, after one executive showed them the money that was being offered to them, the rest quickly got on board, agreeing that it would be a heroically patriotic undertaking.
