Big MT

The Big Mountain Research and Development Center, alternately known as Big MT and the Big Empty, was a privately owned pre-War defense contractor and research center located in the Southwest Commonwealth.

Origins
The Big MT Research and Development Center was originally built inside a cavern system underneath a mountain peak (hence the name) to build the future of mankind and create the technology of tomorrow without restraints, either moral or technical. It welcomed some of the most gifted pre-War scientists, who plumbed the depths of many experimental technological fields. The research conducted within was as groundbreaking as it was unethical, conducted in part on living humans (both American volunteers and Chinese-American detainees). Big MT even included a concentration camp of its very own, safeguarded by lucrative contracts with the US Army, such as the X-42 giant robo-scorpion. However, due to budget cuts in the later years of its operation, Big MT had to improvise alternate means of funding and research. The executives began to strike deals with third parties, exchanging experimental technology for money and other privileges. Due to budget cuts, they even began assassinating non-military targets (Project Hare) to procure research subjects, and exhuming cadaver of previous experimentations (Project Burke - also named "grave robbing" by some scientists) to do new experiments on them.

Due to a failed experiment conducted in the Y-0 research center, the mountain above the center was vaporized, leaving behind a giant crater and the exposed central dome of Big MT. This catastrophe did little to phase the researchers, and the efforts in pushing the boundaries of science continued unabated. The new land exposed by the explosion was adapted for scientific purposes: new facilities were established, both above- and below-ground, including an artillery test field and a test town.

Under the guidance of its six gifted executives, named together the Big MT "Think Tank" executives (Gail Richardson, later known as Borous, the other known only as Mobius, Dala, 0, 8, as well as Klein, the administrator of Big MT, their original names long lost), the facility gave birth to new technologies, such as the Saturnite alloy, next generation hazmat suits, new models of cyberdogs, intelligent stealth suit, holograms, and many more. At the same time, many new horrors were also born in the laboratories of the Big MT: cazadores, nightstalkers, mutagenic plants, ambulatory corpses, unknown toxins, and other fearsome creations. Creations of both types were sold to private parties in exchange for certain favors: Frederick Sinclair obtained various experimental technologies (including even the prototype matter conversion machines) in return for allowing Big MT to use the Sierra Madre as a proving grounds, a decision that backfired catastrophically when the experimental technologies turned on the casino inhabitants, dooming them. Such an event was not unprecedented either: the town of Hopeville was wiped off the map by a disastrous meteorological experiment in another such exchange, later became the Divide.

The Great War
The Great War didn't stop the research efforts; it merely put them on a different rail, and they also began to form hypothesis concerning the post-holocaust economic systems. Sometime after a new project started, with the purpose of preserved the Big MT "Think Tank" executives by transforming them into a special brain bot called like them think tank, allowing them to continue their work at Big MT indefinitely, but "reprogrammed" to forgot a part of their personality and their name, by giving them a new one, enforcing the recursion loop in their new perception programming. With nobody to stand in the way, their research continued, becoming more sinister and debauched as the years went by.

But later, all of its researchers died, probably due to the escape of the cazadores and the nightstalkers. Only the six think tanks remained in the Big MT. Mobius, tired of his endless and horrible experimentation and thinking that "the world isn't ready for that kind of too-far-thing-taking" and that the think thanks had lost what remained of their humanity, erected a radar fence - a kind of radar-guided repulsive field around the perimeter of Big MT to prevent the disembodied brains from escaping into the wasteland, and destroying what little remained of humanity with their new prepared experimentation into a new "fertile testing ground".

After a severe dispute with Klein, Mobius removed all the chips of all personalities of The Sink; his room and personal laboratory, and against his will, hacked the databanks of his colleagues, reprogramming their chronometers, geometers and cartography programs, and making them to lose the sense of time and history. It also creating a belief that the robo-scorpion consumes intelligence (creating the fear to go out of the central Big MT's dome named The Think Tank), he was exiled for a crimes too heinous to remain in recorded memory, and a belief that Big MT it's the world, and nothing exist out of Big MT. However in the process, it also damaged some of their memories and knowledge, creating a mangled, disjointed versions of themselves. Disgusted to have done this to his friends, he also erased some parts of his memory, like this event and his Pre-War creation, the robo-scorpion.

After, Mobius moved to the X-42 robo-warfare facility (that renamed the "Forbidden Zone") and began to "re-create" the robo-scorpion after seen some radscorpions coming into Big MT, with all features of the pre-War model as energy bolts blaster in the tail, eyes and bullhorns systems connected to him. Having now his proper army and thinking that without something to distract them, the radar fence would not be sufficient and he began to send a repetitive threat broadcast to instill and install fear and prompting them to focus on retrieving technologies bringing to attack Mobius. After that, the Big MT fell silent, the remaining think thanks were stuck in The Think Thank dome, forced to continue their work only in this small area because of the fear instored by Mobius, continuously spying them.

Big MT was following more or less abandoned, the sheer size of the crater served as its best camouflage: most wastelanders assumed the ragged edges to be remnants of a massive nuclear explosion and avoided it altogether. The unfortunate few who wandered in disappeared forever, apprehended by robots and lobotomized by the think tanks to act as organic automata, maintaining the decaying facility and protecting it against scavengers. Over the years, it became known in the wasteland as the "Big Empty", a place where nothing exists. Its size and aura of mystery blocked the establishment of trade routes and reliable supply caravans between the Boneyard and New Vegas, a fact that proved crucial to the Legion's survival immediately following the First Battle of Hoover Dam, as the NCR was unable to reinforce its army quickly enough.

The Visitors
Even if the facility's security was almost perfect, three people were able to elude the think tanks and survive its horrors - Elijah, Ulysses and Christine Royce. Elijah came to the Big Empty in search of weapons that would allow him to destroy the NCR and everyone who would oppose him in the creation of a new Brotherhood of Steel order, his order. Elijah scoured the facility for technologies that would be of use to him in his endeavor; after learning of the Sierra Madre from Ulysses, he started gathering equipment that would allow him to crack the casino, the most important and sinister of these were the concentration camp detainment collars, that he experienced during his stay. He also took a unusable holorifle prototype, perfected afterward thanks to the holograms of the Sierra Madre. Ulysses came to this graveyard in search of knowledge, to learn what makes and breaks nations, what would allow him to reawaken America, the Old World. Christine Royce followed Elijah, tasked to kill him for the crimes committed against the Brotherhood of Steel.

Of the three, Christine was the only one who did not escape unscathed. Captured by Big Empty robots following a disastrous skirmish at Little Yangtze caused by an attack of Elijah that sending the survivor of the Little Yangtze against her like walking bombs, she was subjected to horrific experiments in the Y-17 medical facility conducted by some Mister Orderly and Y-17 trauma override harnesses and with a Mark IX Auto-Doc, that permanently damaged her brain, destroying her ability to read and write fluently. She was saved from certain death by Ulysses, destroying the present entities and nursing her back to health in his camp in Big MT. After, he talked to her about philosophy and his desire to go in the X-17 meteorological station and speak with the think thanks.

At some point after Elijah spoke with the think thanks and making them question the way of things. The think tanks began to doubted that their world can be larger than their perceived and installed new ideas in their mind. After, Ulysses and Elijah made contact, at which point Ulysses directed him to the Sierra Madre. Ulysses too spoke with the think tanks, particularly Dr. Klein, who asked a lot about history and asking a dangerous question: "what makes a nation, and what breaks them". Showing them the Old World flag, the think tanks eventually remember many past event especially that there is a world behind Big Empty, a world with ideas and possibilities for experimentation. Dr. Klein, regarded the question too dangerous and reminded him too much events, deleted it from his memory. After coax the answers he wanted out, he returned to his camp to say farewell and pass on information to Christine about Elijah, and he left Big MT to the Divide.

Elijah was the only one who left the think tanks a parting gift. After being apprehended by Dr. 0 and Dr. 8, he hacked them both within minutes, permanently damaging 8's voice module and sewing destruction in his wake: he rode out of Big MT on a cargo train, crashing the remaining trains in tunnels leading out of the facility. During these events, all were observed by Mobius (even the conversation of Ulysses and Elijah with the think tanks), with the inability to act on anything and his growing fear of the future actions of the think tanks.

Some time after the three left permanently, the think tanks installed a pacification field in The Think Tank central area and the Courier was teleported at Big MT by a Big MT's crashed satellite in the Mojave Drive-in. He was taken to The Sink to become a lobotomite but because they suffered a cranial injury in just the right place, it was enough for the Sink Auto-Doc to change its programming to fix the problem and improved the cranial procedure, but in the process, their spine and heart was also removed of their body and replaced with synthetic organs. With The Courier's brain procedural data, this would give to the think thanks the knowledge to modify their cranial selves into host to slip past the radar fence and left Big MT. But after the think thanks extracted it, they fell to bickering amongst themselves. Mobius saw an opportunity to steal The Courier's brain with its knowledge and led it into the "Forbidden Zone". Wanting to gain their brain back and escape, the Courier were obliged to help the think thanks against Mobius by retrieving three pieces of technology, changing the future of Big MT forever.

Layout
Big MT is dominated by the central dome of the Think Tank, which is connected to outlying facilities by numerous walkways, pipes, and conduits.

To the north lies the rail line that passes into Big MT via the Big MT North Tunnel before splitting into two lines that run toward the east and west tunnels. Near the north tunnel is the Forbidden Zone Dome, the lair of Dr. Mobius. Other notable facilities include the Signal Hills transmitter, the Saturnite Alloy Research Facility, the X-22 Botanical Garden, and the X-17 Meteorological Station. Just north of the western train tunnel are the Little Yangtze concentration camp and the Construction Site.

To the east, along the eastern rail spur, lie several notable facilities, including the X-8 Research Center, the X-7b "Boom Town" Target Zone, the Securitron De-Construction Plant, the Hazmat Testing Ground, and the Waste disintegration platform.

The western portion of the crater is dominated by the X-66 Hexcrete Archipelago, a collection of hexagonal concrete structures that vary in size from small platforms to towering monoliths. Among the hexcrete structures are several facilities, including the X-13 Testing Facility, the Z-43 Innovative Toxins Plant, the Z-38 lightwave dynamics Research building, and the X-7a "Left Field" Artillery Launch.

In the southern portion of the crater is Higgs Village, which contains the former homes of the Think Tank within a large, hangar-like structure. It is flanked by the X-12 Research Center and Y-17 Medical Facility.

This is not an exhaustive list of locations within Big MT, but notes some prominent facilities visible from the balcony of The Sink, Dr. Mobius's former apartment, located atop the central dome. For a complete list of locations, see Locations in Old World Blues''.

Creatures
Originally meant as a beacon of new hope for humanity, Big MT eventually created a vast number of horrifying, unique creatures and machines, several of whom have made the Mojave Wasteland their home and killing grounds. Big MT's "legacy" includes:


 * Cazadores - hybrid insect creations of Dr. Borous that broke out of the facility.
 * Nightstalkers - rattlesnake/coyote hybrid creatures, also created by Dr. Borous, that broke out of the facility and developed the ability to reproduce, despite their creator's assurances of sterility.
 * Spore carriers - human victims mutated by plant pollen, the same ones that infected Vault 22.
 * Ghost people - mutated products of The Cloud who stalk the Sierra Madre, another "test field" of Big MT.
 * Lobotomites - countless lobotomized victims of Big MT's experiments.
 * Y-17 trauma override harnesses - robotic suits encasing long-dead bodies they were designed to save.
 * Robo-scorpions - Robotic guardians inspired by scorpions, created by Dr. Mobius.

Appearances
The Big Empty is mentioned in the Fallout: New Vegas add-ons Dead Money and Honest Hearts, and appears in the add-on Old World Blues.

It was to appear in Van Buren, but in later development was merged with the Leavenworth Prison into the Tibbets Prison facility. Tibbets would occasionally still be referred to as the Big Empty by developers in design documents.

Behind the scenes

 * The Big Empty is one of two known facilities to have done research on electrical weapons. The other was the Secret Vault, Vault-Tec's private vault.
 * Despite being one of the defense contractors in the employ of the United States, many of their advanced technology (like K9000 cyberdog gun, holograms, LAER, proton axe, sonic emitter, transportation prototype etc.) were never used by the Enclave, the descendant of the pre-War United States government and the U.S. Army.
 * There are three geographic features called "Big Mountain" in the southwestern US: Arizona's Black Mesa, a peak in Nevada's Black Rock Range, and Big Mountain Ridge, in Los Angeles County, California.
