Behind the scenes[edit]

Much of the following text comes from the timeline in Fallout Bible 0, written by Chris Avellone, which in turn comes from the original Fallout timeline created by Brian Freyermuth and Scott Campbell. Some post-Fallout information was laid out by Rob Hertenstein, and some dates were added by Chris Avellone himself. Additionally, this timeline includes all dates seen or mentioned in Fallout, Fallout 2, Fallout 3, Fallout: New Vegas, Fallout Tactics and Fallout: Brotherhood of Steel, in all Fallout official game guide, in the Fallout Bible as well as Van Buren design documents.

  • The Magna Carta was signed by King John of England and English barons, greatly limiting his authority as king and placing more power into the hands of the feudal government.










  • September 17: The Constitution of the United States was signed by the Constitutional Convention in Philadelphia, Pennsylvania, and ratified by conventions in eleven states. It went into effect on March 4, 1789.


  • December 15: The United States Bill of Rights amended the United States Constitution with ten rights that all American citizens are guaranteed by their government.


  • December 2: President James Monroe proposed the Monroe Doctrine, a policy of the United States which stated that further efforts by European nations to colonize land or interfere with states in North or South America would be viewed as acts of aggression, requiring U.S. intervention.[7]

















  • December 7: Pearl Harbor is attacked by the Empire of Japan.[16]
  • December 11: The United States of America declared war on Nazi Germany.[21][22]


  • Sierra Army Depot is erected. Its mission is to store and maintain a defensive supply of military ordnance. This mission continued until 1991. This is a real event, before the Fallout universe diverged from ours.[23]


  • The Los Alamos Nuclear Research and Development facility, codename: the Reservation, completes construction. Los Alamos becomes part of the research team for the Manhattan Project[24].




1950s: Estimated point of Divergence[edit]



  • May 5: Captain Carl Bell of the United States Space Agency became the first human in space. This claim is disputed by both the Soviet Union and China. Captain Bell's flight in Space Capsule Defiance 7 lasted twelve minutes and seven seconds, and made a full revolution around the Earth.[29] Bell died when the capsule crashed on its return to Earth.[30]


  • Assuming that the flag displayed in the Smithsonian Museum of Technology is genuine, rather than a fabrication by the increasingly totalitarian state, the United States created thirteen commonwealths, creating another, intermediate layer of governance between the state and the federal government. The national flag was amended to reflect this and depicts fourteen stars - thirteen in a circle to represent the commonwealths and one in the middle to represent the federal government and the nation as a whole.[31]
  • July 16: The Virgo II Lunar Lander Valiant 11 with U.S.S.A. astronauts Captain Richard Wade, Captain Mark Garris, and Captain Michael Hagen lands on the Moon. The astronauts become the first humans to walk on a celestial body other than Earth.[32]
  • November 14: Virgo III Lander Valiant 12 lands on the Moon.[33]


  • The mission of Sierra Army Depot is changed. It is now responsible for the demilitarization of stores of surplus ammunition that have been deemed unfit or obsolete for military purposes. This mission is to be overseen by the Industrial Operations Command in cooperation with the Environmental Protection Agency, providing a greener, cleaner way to dispose of military ordnance. The mission continued until 2050.[23]




  • The Delta IX rocket is commissioned by the U.S.S.A. The Delta IX rocket is the last of the manned rockets to the Moon.[36]



  • The last manned mission to the Moon occurs.[36]
  • The Delta IX rocket is converted for U.S. military purposes. Crew and instrument sections are replaced with a nuclear warhead.[36]



  • Template:Icon Prometheus Coal, a division of Poseidon Energy, opens a coal mine in central Utah. As a result a small village is settled nearby called Eagle Rock.[39]
  • An early bug in Mister Handy robots that caused interference in the operation of the multiple arms is fixed with a hardware update, with no major problems since then.[38]


  • Template:Icon The Tibbets Prison is commandeered by the United States government in association with Vault-Tec and Poseidon Oil to tie into their Project Safehouse. On April 5, 2040, the Secretary of the Army makes the decision to build a new Disciplinary Barracks, with a capacity for 456 inmates. A cost ceiling of $363 million in allocated construction dollars is set. The target budget year for funding this project is fiscal year 2041. Construction begins in fall of 2042, with completion projected for fall of the year 2045.[40]






  • The mission of Sierra Army Depot is changed again. It is refurbished with the latest in technology and is from now on used as a secret research installation for developing and testing robotic, biological and conventional weapons until 2076.[23]


  • Seeking to protect business interests and their oil supply, the United States begins to exert increasing pressure on Mexico, citing the political instability and pollution stemming from Mexico as a threat to the United States. Various economic sanctions serve to destabilize Mexico, and the United States military enters Mexico to keep the oil refineries running and making sure oil and fuel continue to make their way north across the border at Mexico's expense.[45]
  • The N99 10mm pistol becomes standard issue military sidearm following the phase out of the N80.[46]


  • A television documentary revealing the withered husk of the Texas oil fields brings the oil shortage into American households and reveals how deep the energy crisis runs.[47]
  • The last manned space flight to the moon to be performed by the USSA takes place. On that flight, the astronauts recover the flag planted on the surface by the Valiant 12 team.[33]
  • The widely known Nuka-Cola’s Dazzling Blue bottle color was adopted as standard after market research programs indicated that the blue color was the favorite in 86 people out of a hundred polled.[48]
  • Template:Icon March 5th: The United States closes its borders.[16]
  • April: Resource Wars begin. Smaller nations go bankrupt as the European Commonwealth declares war on the Middle East in response to rising oil prices.[49]
  • May: The ailing United Nations begins to collapse. In a series of heated debates, many nations withdraw from the organization as the U.N. tries to keep the peace.[50][51]
  • July: The Linden Street slayings of the Pint-Sized Slasher take place.[52][53]
  • July 26: The United Nations is officially disbanded.[54][53]


  • The socially transmitted New Plague arises, killing tens of thousands. The United States closes its borders and the first-ever national quarantine is declared. The source of the plague is unknown, but rumors persist that it is a genetically engineered weapon.[55][56][16]
  • ZAX 1.0 goes online, developed by Vault-Tec Industries. Initially a prototype of some of the systems designed to govern the vaults, it is given to the government to help the Department of Energy collect resource data. Within a year, it is taken by the military for plague and tactical research; one version, ZAX 1.2, would later be constructed for West Tek.[57][58][59]
  • December: Like an exclamation mark on the end of a very bad year, a terrorist nuclear weapon destroys Tel Aviv.[60]


  • REPCONN Aerospace is founded following the first launch of the Delta IX rocket.[61]
  • January: Limited nuclear exchange in the Middle East raises fears throughout the world.[62]
  • In light of the European-Middle Eastern War and the plague scare, the United States officially sets Project Safehouse in motion. The project, financed by junk bonds, is designed to create shelters, called Vaults, for the populace in the event of a nuclear war or deadly plague. Construction begins late in 2054 and proceeds rapidly due to advances in construction technology.[63]


  • West Tek Research Facility is established to continue work on a cure for the New Plague. Their viral research and close ties to the federal government eventually lead to them being chosen for the Pan-Immunity Virion Project twenty years later as well as power infantry armor and laser research.[57][64]
  • ZAX 1.2 is brought in to regulate conditions in West Tek. It is not part of the Vault-Tec preservation software, so it does not have any orders to protect humanity after the bombs fall. In the meantime, it calmly calculates data and plays chess with the scientists. Many scientists claim that ZAX is a "big ol' cheater" and draws the game out too much for a computer of his considerable abilities.[65]





  • The Anchorage Front Line is established, as the United States increases its military presence in Alaska to protect its oil interests. The Anchorage Front Line causes tensions in the United States and Canada, as the United States attempts to pressure Canada into allowing American military units to guard the Alaskan pipeline.[70]
  • The first artificial Intelligence is born. Limited by memory constraints, its expansion is rapidly halted. The discovery paves the way for future A.I. research in laboratories throughout the United States.[71]


  • Traffic on the streets of the world stops moving. Fuel becomes too precious to waste on automobiles, so alternatives are explored - electric and fission-powered cars begin to be manufactured, but factories can only make limited amounts while conserving fuel. Pressure on fusion research increases.[72]
  • The European-Middle Eastern War abruptly stops as the oil wells in the Middle East no longer produce oil. With the fields exhausted, neither side has a reason to continue hostilities. Both the Commonwealth and the Middle Eastern states are almost completely ruined by eight years of war.[73]
  • The European Commonwealth falls apart, reduced to hostile nation states, fighting over the remaining resources. The European Civil War begins.[74]




  • Template:Icon Dr. Willem Clark, a top nuclear physicist in his day, is put in charge of all scientific endeavors at the Reservation. Colonel Green, a career soldier in the U.S. army, is put in charge of security.[24]
  • August: The construction of most Vaults completed, except for Vault 13, whose construction finally gets off the ground heralding a development cycle that seems plagued with problems. Drills begin in the other cities with completed Vaults, but the increasing frequency of the drills has a "cry wolf" effect, and the turnouts for drills trickle off as the years go on.[80][81]


  • Template:Icon A photograph of Dr. Clark, Dr. Sebastian, and the Maniac AI surfaces during the lull between the remobilization of Los Alamos and the arrival of its new mission orders.[24]
  • March: Construction of Vault 106 begins.[75]


  • Template:Icon The Reservation is given orders to research and produce nuclear missiles that can be fired from an orbiting space platform.[24]
  • February: Construction of Vault 76 begins.[75]
  • April 14: M.A.R.Go.T. enters service.[82]
  • June: Due to enormous demands for electricity from a 17+ million population, a nuclear reactor in New York City goes supercritical, almost causing a meltdown. The near meltdown brings into effect power rationing, and the term "Hot Summer" is used to refer to this incident.[83]
  • August: Increasing need for mobility in the United States mechanized cavalry leads the military to focus the efforts on creating a man-based tank - essentially, a two-legged walking armored unit: power armor.[84] Research grows until 2067 and several prototypes are developed, many of which prove to be unworkable in the field. These prototypes pave the way for future advances in military, construction, and fusion technology.[85]


  • The U.S. Army conducts a test of a next generation nuclear weapon, dubbed the Super Bomb by the media.[86]
  • The U.S. Navy missile cruiser USS Ebon Atoll is accidentally sunk by the U.S. Navy Submarine USS. Interference during the Anchorage Campaign. The Interference mistook the Ebon Atoll for an enemy vessel and shot it with a nuclear torpedo killing all on board. It is one of the worst U.S. Navy disasters since World War II.[87]
  • Template:Icon Resource rationing in Denver results in Food Riots, after the midwestern parts of the United States and Mexico cannot supply enough food for the population. National Guard units are called in to deal with the situation.[88]
  • Template:Icon Poseidon Energy shuts down the Eagle Rock mining complex due to the danger and expense. The installation is sold to the government.[39]
  • May: Construction of Vault 87 begins.[75]
  • Spring: As the oil resources dry up across the globe, China's fossil fuel dependency causes an energy crisis in the nation. China, bordering on collapse, becomes more aggressive in its trade talks with the United States. Unwilling to export oil to China, talks between the United States and China break down.[89]
  • June 24: Negotiations between the U.S. and other world powers come to a dramatic end, with the president walking out of oil talks with the other world powers. After a much heated debate, the president stormed out of the meeting and declared that the last known supply of petroleum will be used exclusively by the U.S. and the U.S. will not sell or trade any oil to outside parties.[90]
  • Summer: Adding further insult to the Sino-American relations, the first crude fusion cell is unveiled, one of the results of the power armor project. Devices designed for the fusion cell begin to be manufactured. Incorporating fusion power into the general U.S. infrastructure begins, but the process is too slow to supply power to the regions that need it. Nearly eleven years later, few sections of the United States were supplied with fusion power.[91][92]
  • December: In the winter of 2066, China invades Alaska. The Anchorage Front Line becomes a true battleground.[93][94][95] The United States Congress unanimously passes and the then-President of the United States signs the U.S. Declaration of War on China, officially marking the beginning of the Sino-American War.
  • December: As a sign of increasing tension between the two countries, Canada proves reluctant to allow American troops on Canadian soil or allow American planes to fly over Canadian airspace. American and Canadian tensions rise, but Canada eventually backs down, and U.S. troops pass through Canada. This sets the stage for the Canadian annexation in 2076.[93][96]


  • The first suit of T-45d power armor is deployed in Alaska. While lacking the full mobility of future versions, this power armor is incredibly effective against Chinese tanks and infantry. Its ability to carry heavy ordnance becomes key in various localized conflicts, and it has the power to destroy entire towns without endangering the wearer. China rushes to create its own versions, but they are many years behind the United States.[97]
  • A Nuka-Cola machine can be found on almost every street in America.[42]
  • Template:Icon Senator Todd Peterson decides to build a secret bunker to house himself and his family should war break out. Senator Peterson is a wealthy man in his own right, but lacks the funds necessary for such a project. Through secret dealings with Poseidon Oil and a covert branch of the government known as the Enclave, the final funding for the project is attained. A construction site is chosen in southern Colorado and work begins.[98]



  • Canada begins to feel the pressure from the United States military as the U.S. draws upon Canadian resources for the war effort. Vast stretches of timberland are destroyed, and other resources in Canada are stretched to the breaking point. Many Americans refer to Canada as Little America, and Canadian protests are unheard.[99]
  • February 11: By order of the U.S. government, all Patriot's Cookbook magazines are banned and incinerated. However, many magazines still remained in circulation.[100]
  • March: Vault 13 is finally completed - it is the last of the Vaults on the West Coast,[101] and drills begin. Due to its late completion, the "cry wolf" effect that hurt the other Vaults is not as pronounced.[80][102]
  • October: Construction of Vault 76 ends.[75]
  • December: Construction of Vault 106 and Vault 108 ends. Vault 108 was in construction for 8 years due to work stoppage.[75]


  • The first of the Chryslus Motors fusion-driven cars are developed. Reassuringly big and American, the limited models carry a hefty price tag but are sold out within days. Many Chryslus plants have long since been converted into making military ordnance.[103]



  • Template:Icon Completed B.O.M.B. missiles are sent to different space centers around the U.S. so they can be carried into space and installed into the B.O.M.B. satellites. The process is slow, but it is being carried out fairly regularly.[24]

  • June: The United States Army confirms the development of a "Super Weapon" to liberate Anchorage Alaska.
  • June 3: The United States' increasing demand for Canadian resources causes protests and riots in several Canadian cities. An attempted sabotage of the Alaskan pipeline is all the military needs as an excuse to finalize its annexation of Canada, which had already begun in 2067.[93][106][107][108][109]


  • Template:Icon August: The Ballistic Orbital Missile Base, or B.O.M.B.-001, is completed and partially functional (for security and maintenance bots) using a temporary onboard generator. The only thing the base needs are the manually input final launch instructions and codes, and the main power reactor.[110][111]
  • September 15: As China becomes increasingly aggressive with their use of biological weapons, the United States government felt that a countermeasure was needed. The Pan-Immunity Virion Project is officially formed and plans are made to begin experiments at the West Tek Research Facility in Southern California.[112][113]


  • Despite claiming that it fights a purely defensive war, United States units are deployed to China. Long supply lines and difficult conditions on the mainland lead to the units becoming bogged down in fighting. American infantry, mechanized divisions, and power armor units suffer from strained resource and supply lines.[114]
  • Template:Icon The government turns the lower levels of Eagle Rock into a radioactive waste dump. Future founders of the Enclave help Poseidon Energy secure a contract for the operation, leading to the development of Agricola robots and the installation of a bunker on site.[39]
  • June: Construction of Vault 112 ends.[75]
  • Template:Icon July: Bloomfield Space Center is completed. It is tasked with building Hermes XIII and Hermes XIV, rockets meant to service B.O.M.B.-001 and -002 respectively. Originally meant for Mars missions, the rockets are instead to be used for installing the final elements of the orbital base (reactors), entering final launch instructions, and performing a final check of the station.[110][111]


  • The Sierra Army Depot A.I., Skynet, becomes self-aware.

  • RobCo brings up plans to purchase REPCONN Aerospace, threatening a hostile takeover otherwise.[116]
  • March 21: PVP experiments continue at West Tek with batch 10-011, in the wake of successful tests of the virus on single-celled organisms. Experiments on plant cells are postponed. The pan-immunity virion is renamed Forced Evolutionary Virus (FEV).[117][118]
  • May 9: F.E.V. experiments continue at West Tek with batch 10-011, in the wake of successful tests on flatworms; the flatworms exhibit increase size and heightened resistance to viral contagions. Experiments with insects have less success, and further experimentation on insects is postponed by Major Barnett.[117][119][120]
  • May: Vault 112 seals two years early, for Stanislaus Braun's sadistic desires.[121]
  • June 30: F.E.V. experiments continue at West Tek with batch 10-011, with white mice as subjects. Increased size, muscle density, and Intelligence are noted.[117][122][123]
  • November 9: FEV experimentation (batch 10-011) on rabbits is concluded. Increased size, Intelligence, and (this time) aggressiveness is noted. Apparently, it was hard to determine whether the flatworms in the previous experiments were angrier and more violent than normal. Frankly, the researchers cannot be blamed for this.[117][124]


  • RobcOS v.85 is copyrighted.[125]
  • REPCONN Aerospace is bought out by RobCo Industries.[61]
  • January 3: A military team under the command of Colonel Spindel is sent to the West Tek research facility to monitor the experiments in the interest of national security, due to fears of international espionage.[34] Captain Roger Maxson (the grandfather of John Maxson, the High Elder of the Brotherhood of Steel in 2161) is among the team personnel.[126]
  • January 12: Splicing in several new gene sequences into their test virus, dogs are injected with batch 11-101a at West Tek. Although increased strength was noted, increased intelligence was not.[127] Using batch 11-011, experiments are conducted on raccoons. The same results are noted, but the attempted escape of several infected raccoons causes Major Barnett to terminate the escape... and the test subjects. Two pairs of raccoons, however, are unaccounted for.[128]
  • January: The United States annexation of Canada is complete. Canadian protesters and rioters are shot on sight, and the Alaskan Pipeline swarms with American military units. Pictures of atrocities make their way to the United States, causing further unrest and protests.[93][130]
  • April 15: Once all secondary tests and studies are done on the test subjects, all dogs from the batch 11-101a Forced Evolutionary Virus (FEV) tests at West Tek are terminated... from a safe distance.[117][131][132]
  • June: Power armor T-51b series prototype completed, resulting in the T-51b power armor. This is the pinnacle of power armor technology before the Great War. Many of these units are sent to China, and they begin to carve a swath through the Chinese forces. The Chinese resources are strained to the breaking point, and the supply lines from the nations China has annexed begin to break down.[133]
  • July: Flotation Homes and Seaweed is published by Vault-Tec Industries.[80]
  • August: Food and energy riots begin in major cities throughout the United States. Military units begin to be deployed in cities within the United States to contain rioters, and many temporary prisons are constructed. A state of emergency is declared, and martial law soon follows.[134]

  • Template:Icon October: Due to the seriousness of world events and the threat of nuclear war, Hermes' launch is postponed while funds are routed to vault technology. Launch is rescheduled for 2077.[110][111]
  • October 4: At West Tek, fifteen chimpanzees are infected with batch 11-111. The most successful test to date, growth and immunities in the chimpanzees surpass all other subjects to date. The military practically drools over the results. Plans are made in secret to begin testing in small quarantine towns in North America, and the Mariposa Military Base construction is sped up in anticipation of moving the West Tek project to a location under military supervision.[135]
  • Template:Icon November: Enclave personnel seize control of Bloomfield Space Center and begin researching and developing a way to convert Hermes XIII and 14 into a personnel transports to transport important individuals off-planet.[110][111]

  • January 10: Alaska is reclaimed, and the Anchorage Front Line is again held by the Americans.[144][145][146]
  • January 22: The first domestic use of power armor within the United States for crowd and quarantine control. Units originally serving in China and the Anchorage Front Line find themselves fighting Americans at home. Food riots increase, and many civilians are killed. Several soldiers defect from the military both in Canada and the United States. They are captured, and are sent to military prisons.[147][148][146]
  • February: F.E.V. Research is leaked to the world through an unknown source. Protests in many major cities and governments around the world, as well as accusations that the U.S. was responsible for the New Plague. F.E.V. is seen as the threat, and serves only to fuel tensions. The governments of the world fear what the U.S. is up to. Speculating anything from trying to make a breed of super soldier, to trying to make Hitler's master race, they begin to panic.[149]
  • February 16th: The testing of the Archimedes I weapons system was successful. However, despite precautions being taken, several minor systems were overloaded.[150] Furthermore, both the Black Mountain communications array and the Hidden Valley military bunkers experienced system frying power fluctuations at the time of the testing.[151] However the Archimedes II testing was pending the long-range communication/targeting system on the Euclid's C-Finder.[152]
  • February 22nd: The Army takes control of the HELIOS One installation in Nevada from Poseidon holdings. Full use of the laser artillery enters the American arsenal.[153]

  • August: Sometime prior to August 15, General Constantine Chase, the hero of the Anchorage Reclamation, begins testing a virtual reality simulation of the Reclamation at the V.S.S. Facility in Washington, D.C.
  • September 6: Technicians at the V.S.S. Facility notice General Chase is making radical, unrealistic changes to the Anchorage simulation. They believe Chase is becoming obsessed with the simulation and is gradually going insane, but refrain from confronting him out of fear that they will lose their jobs to military contractors.
  • October 10: Captain Roger Maxson and his men discover that the scientists at Mariposa have been using "military volunteers" (military prisoners who didn't have their brains scooped for use in robobrains) as test subjects in their experiments. Morale in the base breaks down, and in light of the mental breakdown of Colonel Robert Spindel stationed at the base, Maxson's men turn to him for leadership.[156][157]
  • October 13: After an interrogation, Maxson executes Robert Anderson, the chief scientist at Mariposa.[156]
  • October 15: Colonel Spindel commits suicide.[156]
  • October 18: Scientist executions at the Mariposa come to an end.[156]
  • October 20: Captain Roger Maxson, now in control of Mariposa, declares himself to be in full desertion from the army (via radio)... and receives no reply.[156][158]

    • 82 students from the Early Dawn Elementary school go on a field trip to Lamplight Caverns with a couple of teachers and a few parent chaperons.[161]
    • In the early morning (U.S. Eastern Standard time) the war begins, triggered by an unknown party. The United States and China deploy their nuclear arsenals. Other countries, seeing the missiles on their way, launch their planes and fire their warheads as well. Air raid sirens sound, but very few people heed the warning. The vaults are sealed. Two hours of nuclear bombardment later, the War ends, along with much of humanity.[156]
    • Randall Clark witnesses the destruction of Salt Lake City and, by extension, the death of his family. The city is hit by thirteen nuclear warheads, resulting in total destruction.[162]
    • Mr. House saves Las Vegas and most of the surrounding area from complete destruction with his defenses at the Lucky 38, stopping 68 of the 77 ICMBs launched at Las Vegas (59 through forced deactivation and 9 destroyed with laser cannons mounted on top of the Lucky 38). The resulting "light show" can be seen as far as Mexico City.[163] Nine of the warheads evade destruction, a fault of Mr. House being forced to use an inferior operating system without the Platinum Chip, but only damaging minor parts of the Mojave Desert, with the most damaging detonation being near Nellis Air Force Base.[164]
    • The Sierra Madre gala event begins, but is cut short by the war. The casino hermetically seals itself and the holographic security murders many of the guests. The few scattered survivors eventually commit suicide in the following hours and days. Vera Keyes dies from an overdose of her pain medication, while Frederick Sinclair dies in his attempt to disarm his traps. The only known survivor is Dean Domino.
    • Vault 12 fails to close properly. Once it becomes known that the other vaults have sealed, people within Bakersfield attempt to force their way into Vault 12 to protect themselves and their families.[165][166]
    • The West Tek Research Facility is hit by warheads, breaking open the F.E.V. tanks on levels four and five and releasing it into the atmosphere. Mutated by radiation, it loses its mutagenic abilities, but it later complicates things for the Master.[167]
    • The Mariposa Military Base survives; the soldiers within protected from the radiation and FEV flooding the wasteland.[156][168]
    • Template:Icon Surviving scientists and soldiers based in Los Alamos band together with other survivors they encounter for safety. They set up a temporary camp in a cliff dwelling at Mesa Verde and attempt to contact the federal government for further instructions. No contact is ever made. A small vault is built into the cliff side to shield the only computer they have from the elements.[169]
    • Template:Icon All Enclave personnel leave Bloomfield to either take cover or maintain "hot spots". Sub-reactor is turned off. Bloomfield, B.O.M.B.-001 & 002, and Hermes XIII & 14 are completely forgotten.[110][111]
    • Template:Icon Two Poseidon scientists are trapped in the AGRICOLA Lab. After four years, one dies of natural illness. After one more year, the other commits suicide.[39]
    • Template:Icon Due to seismic activity, some radiation seeps into the sub-levels of the Reservation. Even though the people underground are safe from the blasts, radiation eventually takes its toll.[24]
  • October 25: At Mariposa, Platner, bound in power armor, is sent out to get specific readings on the atmosphere. He reports no significant radiation in the area surrounding the facility.[156][170]
  • October 27: After burying the scientists in the wastes outside of Mariposa, the soldiers seal the military base, then head out into the desert, taking supplies and weapon schematics with them. Captain Maxson leads his men and families to the government bunker at Lost Hills.[156][171]
    • Note: Although Maxson's points in his holodisk indicated that civilian personnel other than the families of soldiers under his command were to remain at the base, whether they did so or not is unknown.[172]
  • October 28: After having wandered for five days, Randall Clark takes refuge in a former USGS research station inside a cave in Zion Canyon.[162]
  • October 31: A black rain begins to come down in areas across the United States and likely the globe, causing a spike in radiation levels in affected areas.[173]
  • November: Captain Maxson, his men, and their families, arrive at the Lost Hills bunker a few weeks later, suffering many casualties along the way, including Maxson's wife (but not his teenage son). The surviving soldiers go on to become the Brotherhood of Steel.[174]
  • November: During the Exodus, a faction within the Brotherhood of Steel led by Sergeant Dennis Allen breaks off to explore the southeast Glow to recover technology. The Captain refuses to permit that, so Allen and his separatist group splits away from the Brotherhood of Steel, taking power armor and weapons with them.[175][176]
  • November: The separatists make their way to the West Tek research facility. They arrive there twenty days later, and are promptly chewed apart by the West Tek's unforgiving automated defense systems. Wounded, Allen begins to suffer radiation poisoning from a leak in his suit. Before he dies, he logs what happened to the expedition into a holodisk.[175][176]
  • November: Ms. Carrie Delaney is the last adult to leave Little Lamplight Caves in search for help. Ten year old child Jason Grant takes charge in her absence.


  • January 8–10: What sounded like a two day windstorm occurred in Zion Canyon, the radiation dropped 500 rads.[177]
  • January 15: Glowing green snow fell in Zion Canyon.[177]
  • January 28–30: The background radiation in Zion Canyon is finally low enough for Randall Clark to explore outside the USGS research station. He quickly finds himself to be the only living thing in the immediate vicinity.[177]
  • The dwellers of Vault 87 are locked in airtight chambers and exposed to the FEV by the Vault's Overseer and his security, who are simply, though callously, following the "plan" laid out by Vault-Tec. The vault's population is transformed into super mutants.[178]
  • The city of kids, Little Lamplight is officially founded. By unanimous vote Jason Grant is named as the city's first mayor.[179]


  • The first effects of radiation are seen in the survivors. Widespread mutations occur with animals and humans alike. Those that survive the effects of the mutations are permanently changed. New species are created almost overnight.[180]
  • Template:Icon John Bloch's military group makes a peace-protection pact with local ranchers.[181]


  • The Skynet AI, in Sierra Army Depot, becomes self-aware, according to its own records.



  • April 10–~June 17: Randall Clark leaves Zion Canyon to visit Salt Lake City, circling pockets of radiation and scavenging. Outside of Nephi he caught the trail of three men heading toward Fountain Green, he didn't follow however, believing them to be cannibals bue to the missing corpses of the old couple he mercy killed on the day of the Great War.[184]
  • Spring: Set takes control of Necropolis, wrestling control from the original Overseer. The Vault 12 Overseer, not willing to take a dirtnap, is driven north and history loses sight of him.[185]


  • The planned date for the U.S. military to bring the VB-02 Vertibird, a Vertical Take Off and Landing (VTOL) aircraft, into service.[186] For obvious reasons, this never happens, but the Enclave resumes development after regaining its footing.


  • Template:Icon December: After most of the initial survivors in the Reservation succumb to radiation, those "fortunate" enough to not die have turned into ghouls. And after spending ten years underground, they finally come back to the surface. Twelve ghouls, including Dr. Willem Clark, volunteer to search the wastes in the hopes of finding other survivors.[24]


  • Template:Icon The computer in Mesa Verde fails. The scientists resort to carving their most important schematics into the kiva walls.[169]
  • Template:Icon December: Of the twelve volunteers to explore the wastes, only one comes back to the Reservation; Dr. Willem Clark. However, he has brought back a few dozen fellow ghouls to seek shelter at the Reservation.[24]


  • Template:Icon Scientists in Mesa Verde began to drill the village children in the ways of mathematics and science so that knowledge is not forgotten. They hope that their descendants will one day help bring civilization back to the wasteland.[169]
  • Template:Icon January: After explaining the hardships and prejudices placed against ghouls by smoothskin humans, the ghouls of the Reservation proclaim Dr. Willem Clark as their leader. Willem further solidifies his place as leader by explaining his plans to one day make the ghouls the rightful and true heirs to the Promised Earth and that becoming a ghoul was the next, logical step in the evolutionary process.[24]


  • Vault 29 opens. Harold sets out to make his fortune as a trader, making the circuit around the survivalist communities in the wasteland.[187][188]


  • Vault 8 opens, and they use their G.E.C.K. to create fertile ground for their city. This eventually becomes Vault City.[189]
    • Note: While Lynette says that the city was founded 120 years ago, which would place the event around 2120, the Chosen One later says that it's 70 years before the Vault Dweller left Vault 13. This probably means that Fallout 2 was initially meant to take place earlier, and the dialogue file was not corrected.[190]


  • The Los Angeles Vault opens, the Boneyard is founded and attracts survivors.[191]
  • Dr. Richard Moreau is exiled from Vault City for murder. The circumstances surrounding the murder are unknown, but he changes his last name to Grey and heads south.[192]


  • The Hub is founded by a man named Angus, who sets up camp around a filthy oasis in the desert, and he proceeds to begin trading with other settlements.[193]


  • September 20–November 15: 28 Mexican survivors – eleven male, eight female and nine children – settle in Zion Canyon.[194]


  • Harold rises to the level of a caravan boss in the Hub. His caravans suffer occasional attacks in the wastes, but Harold's caravan outfit survives and prospers... until the mutant attacks begin to pick up a few years later.[195]
  • February: The inhabitants of Vault 22 leave their vault due to an outbreak of mutated spores infecting most of the dwellers and overrunning the Vault.
  • February 11: About 118 survivors of Vault 22 move out of the Mojave wasteland and travel to Zion Canyon. Most are infected with the spores and bring spore carriers and spore plants to the Zion Valley and attack/kill most of the Mexican survivors already in Zion.[196]
  • February 14: According to Randall Clark, the Vault 22 survivors eat the Mexican survivors they took captive.[196]
  • February 19 - January 13, 2097: Randall Clark begins to ambush the Vault 22 survivors and continues to until the remaining 34 survivors leave Zion.[197][198]


  • January: J. Hendricks becomes overseer of the remaining Vault 22 survivors, and as his first order as overseer orders everyone to leave Zion Canyon.[197]
  • January 13: The thirty-four Vault 22 survivors leave Zion Canyon after 10 months of ambushes from Randall Clark.[199]
  • A man named Jonathan Faust leads his group of about 200 people from the overcrowded Vault 15 into the wastes of the outside. Eventually they become a raider band known as the Vipers.[200]



  • May 22: Increasing mutant attacks on Harold's caravans frustrate him to the point of financing and leading an expedition to find out where the mutants are coming from. Consulting with a scientist and doctor at the Hub, a man by the name of Grey, the two of them decide to join forces.[202]
  • June 23: Richard Grey's expedition (including Harold) finds the Mariposa Military Base and is summarily scattered and defeated by the mutant inhabitants. Grey is knocked into one of the vats of Forced Evolutionary Virus (FEV) by a robotic arm, and Harold is knocked unconscious, only to awaken later out in the wasteland.[203]
  • June 27: Harold, already mutating, is found by traders and taken back to the Hub. His former caravan partners and employees, horrified by his condition, abandon him.[204]
  • July: Richard Grey, now horribly mutated by the virus, crawls from the vat, covered with F.E.V. and in terrible pain. Barely able to think or perceive his surroundings, he crawls into the vat control room and begins his audio log. He fades in and out of consciousness, sometimes for days or weeks at a time.[205]
  • July–November: Richard Grey begins to acclimate to his condition, and begins his first tests of animals by exposing them to F.E.V. These experiments and his growing awareness lay the foundation for his plans for the Unity and the master race. He takes the name "the Master".[206]
  • November: The first human victim wanders into Mariposa, and Grey consumes him.[207]
  • December: Grey continues his experiments on wanderers that enter Mariposa with no success. The creations are flawed (due to the radiation counts in their bodies), making them big but incredibly stupid, and Grey consumes them rather than letting them live.[208]


  • January: The Master discovers the problem with the influence of radiation on his mutations, and he begins to choose his subjects more carefully. The first classic super mutants are born. He begins his plans to build an army.[209]
  • 2103-2130: Throughout this period, the Master begins slowly gathering test subjects, willing or unwilling, from local human stock. The Great Winter of 2130 and the scarcity of human subjects make building his army difficult.[210]


  • August 22–September 3: Randall Clark tracks 10 sets of barefoot tracks northeast of the Zion Canyon entrance, and finds feral ghouls, which he believes to be the result of dementia until they attack him on sight. Over a little more than a week, he rids Zion of the ghouls.[211]


  • February 5-6: Randall Clark attempts to commit suicide on his 60th birthday, with the help of a bottle of Whiskey and a 12 guage shotgun.[212]


  • Angus establishes himself as governor over the Hub.[213]
  • Skynet is given final orders by its masters, then left to rot in Sierra Army Depot.





  • January 2–22: Randall Clark begins leaving gifts, like books and medicine, and notes for the children to make the most of their new home. He signs every note as "The Father". The children later form the tribe the Sorrows. Clark also realizes that he is terminally ill, probably with lung cancer.[219]
  • January 23: Randall Clark makes his final notes as he climbs up Red Gate to make sure the children will not find his body, and reveal the mythological "Father" figure to merely being an old man. He dies peacefully shortly afterwards.[219]


  • The Vipers attempt to raze the Hub in its formative years. Despite the numerical advantage, they are defeated by a coordinated defence led by Angus. Beaten, they retreat to the north.[200]
  • Winter: Angus is murdered. The Hub is thrown into chaos.[220]
  • Spain emerges as the technological and economic leader of the European union, and begins instituting policies that lead to the eventual separation of the eastern members of the European Union.


  • A band of merchants seizes the water tower in the Hub. They demand anyone wanting water must pay a toll. The Great Merchant Wars begin.[221]
  • 2126-2128: The Great Merchant Wars are fought, the Water Merchants seal up the town, but are outnumbered.[222]



  • A man named Roy Greene makes peace in the Hub and negotiates a settlement. The Hub's Central Council is formed, composed of two representatives from each of the Hub caravan companies. A long period of indecisiveness and meetings maintain the status quo in the Hub.[222]



  • A group of machinists comes to the Boneyard, settling into an old, abandoned factory and beginning to manufacture weapons and ammunition.[225]
  • 2131-2135: The Master begins ordering his super mutants to gather human stock from caravans. For many years, the caravan disappearances are blamed on monsters in the desert, and even when the abductions begin to occur on Hub caravans, the deathclaws are blamed. The super mutant army grows.[226]


  • Elder Roger Maxson dies of cancer, and his son, already an accomplished soldier, takes up the role of "General" (Elder) within the Brotherhood of Steel. John Maxson becomes a member of the Paladins, showing tremendous promise as a soldier.[227]


  • The Master begins to mass-produce super mutants. Only about one in six or one in five attempts are successful, and of these successes, only half seem to last to go on to be part of his growing army, called the Unity.[228]




  • The brutal eastern European winter forces the Belukr tribe to flee from European Union territory. In the following spring, the tribe makes its way to Moscow, where they encounter the Muscovite Vault Dwellers.


  • Around the early 2150s the Vipers recover from their defeat by Angus at the Hub, replenish their ranks from captured slaves and caravan drivers, and begin to establish a power base in the badlands to the North of the Hub (and south of the Lost Hills Bunker). Driven by a religious frenzy (and the need to provide for their much larger numbers of soldiers and disciples), they begin raiding more frequently than before, attracting the attention of the Brotherhood of Steel.[200]


  • The Brotherhood of Steel Elder Council sends out Knights to seek traces of Sergeant Dennis Allen's separatist group. All they find is ruins.[175]
  • Crimson Caravan Company is founded by Demetre Romara.[231]
  • The Boneyard machinists run out of scrap in the surrounding area, form trade relations with Adytum.[225]


  • As their influence slowly spreads throughout the wastes, the Master finds humans, doomsday cultists, and rather than dip them in the vats, he demands their obedience as spies - their leader is a man named Morpheus, an ex-member of the gang called the Rippers, and he pledges his followers to the Master. Morpheus and his cultists form the future core of the Children of the Cathedral.[232]


  • Vault 760-C opens. The residents begin rebuilding Vancouver, Canada, and scouring the wastelands for music.



  • The machinists in the Boneyard name themselves Gun Runners.[233]
  • The Brotherhood sends out a few squads of scouts to track the Vipers down - it is more of a training exercise conducted by John Maxson's father, as the Brotherhood is convinced that small detachment of troops in power armor would be sufficient to deal with a group of raiders, no matter how large. One Brotherhood squad, lead by Maxson, finds the Vipers. Expecting the raiders to break and run, Maxson doesn't take into account the religious ferocity of the Vipers (or their poisoned weapons), and when a single arrow nicks him with his helmet off, he dies within hours. John Maxson takes up the role of Elder, and Rhombus becomes the new head of the Paladins.[200][234]
  • The Paladins, now led by Rhombus, begin a full scale campaign against the Vipers, tracking them down and wiping out almost all of their members within the span of a month. Some of the Vipers are able to flee north and east into the mountain range.[200]
    • Note: According to Chris Avellone's Fallout Bible #6, the Vipers were never heard from again. It was added there possibly because they don't appear in the final game, but it is inconsistent with Fallout, where the Vipers are mentioned by several characters (Ian, Aradesh, Killian) as still being around. The surviving Vipers must have therefore been still active in California until at least 2161. Furthermore, small groups of Vipers can be found in the Mojave Wasteland in 2281.
  • After capturing a caravan of vault dwellers, the Master learns the location of the Boneyard Vault, the future site of the Cathedral. He conquers the inhabitants and sets up operations there, and the human cultists begin to use the Vault as their powerbase. Within the Vault, the Master begins to send out patrols to Vault locations in search of these other Vaults. This move is finalized in the subsequent year, 2156.[235][236]


  • The Master sees advantages in establishing a benevolent "religion" (the Children of the Cathedral), and using them as spies in settlements throughout the wastes. Missionaries from the Children of the Cathedral spread slowly across the wasteland, acting as eyes and ears for Morpheus and the Master.[237]


  • The Master learns the location of the Bakersfield Vault, Vault 12, and sends a detachment of super mutants there to seize the vault. Many ghouls are snapped like twigs in the attack, and Set finally parleys with the super mutants, telling them that the ghouls are the Vault survivors the super mutants are looking for. The super mutants, angered at failing to find an intact Vault, set up a small garrison at the watershed to watch the inhabitants and ensure Set's...cooperation in the war to come.[238]


  • Regulators take control of Adytum. The trade relations with the Gun Runners sour, as the trade begins to favor the settlement heavily.[239]

With the help of other crash survivors, he reorganized the mutant group into a fighting force. However, he began to notice symptoms of brain damage sustained in the duel: Hallucinations and bouts of angers and depression.[266]


  • Template:Icon April 9th: Gammorin's forces inadvertedly wake up the Calculator, nearly leading to a holocaust of epic proportions.[267]

    • Note: The broken handgun is the one you see on her table in the opening movie of Fallout 2.[277]
  • February 2: The Vault Dweller's daughter ascends to role of Village Elder. She rules with a steady hand, and her wisdom is greatly respected.[278]

  • October: Melchior begins to mutate, but keeps his intelligence and cunning in the wake of the transformation, making him smarter than your average super mutant. Realizing that the Enclave will kill the super mutants after they get the FEV data, he begins to use his magician talents to hide away weapons for the mutants to defend themselves when the Enclave decides to dispense with them.[292]
  • 2236-2238: Horrigan gradually mutates from exposure to FEV, gaining the physique and slow, stupid, single-mindedness of a super mutant. He is kept heavily sedated, operated on, and studied. He is conscious for only brief periods at a time, then quickly sedated after the bloodshed is over.[293]


  • The remnants of the Naval Research Institute lead by Horace Pinkerton clear the mirelurks off the wreck of a beached aircraft carrier that later becomes Rivet City.[294]

  • May 16: Less than a day later, Vault 13 is opened, only to be greeted by two Enclave verti-assault squads. The squads kill three of the vault dwellers who were "resisting capture" and storm Vault 13, kidnapping all the inhabitants.[314]
  • May 17: Enclave animal handlers drop an intelligent deathclaw unit into Vault 13 from a safe distance to kill anyone investigating the vault and cloak the Enclave's presence. Other intelligent deathclaws are sent into the desert surrounding Vault 13 to check for any escapees or witnesses.[315]

  • Fall: Fallout 2 ends - The Chosen One enters the Enclave's oil rig using the damaged tanker and destroys the Poseidon oil platform, killing the President of the United States and ending the Enclave's plans for world domination.[316]
  • After the Enclave's destruction, the refugees of Arroyo and Vault 13 resettle, building a new community with the aid of the Garden of Eden Creation Kit. Finding themselves hundreds of miles from their Vault, the members of Vault 13 choose to join the villagers in establishing a new community, and their technical expertise, combined with the villagers survival skills, allow the new settlement to grow and prosper. Two generations of the same bloodline are re-united, and their savior, the Chosen One, becomes Elder, presiding over the village in the years to come.
  • The Arroyo elder lives for many years after the destruction of the Enclave. She seems pleased that the ancient separation between Vault 13 and the Vault Dweller has been reconciled, and many are the times she tells the Chosen One she wished the Vault Dweller were alive to have seen the reconciliation take place. Certain that the safety of the new village had been secured and the new community was flourishing, the Elder passes away a few months later in her sleep. Many of the older Arroyo residents believe that she now lives in the vault of the sky, telling the Vault Dweller of the Chosen One's brave deeds.

  • Template:Icon Optimizing Gecko's power plant becomes the first step in forging a spirit of cooperation between Gecko and Vault City. Gecko's increased power production becomes instrumental in helping Vault City's expansion.
  • Not long after the destruction of the Enclave, the Bishop Family of New Reno is blessed with a child. This child seems to have little in common with the Bishops, preferring instead to spend his days exploring the wastes.[317] When he turns thirteen, he seizes control of the Bishop Family and leads them to victory over the remaining New Reno families. He dies quietly in his sleep at the age of seventy-three, never having known his real father.[318]
  • Myron dies less than a year after the defeat of the Enclave, stabbed by a jet addict while drinking in the Den. His discovery of jet is quickly forgotten, and now there is no one who remembers his name.[319]
  • The Chosen One still hears mention of Harold from time to time. Apparently, the tree growing from his head has gotten larger, and if rumors are to be believed, fruit is growing from it. The seeds are said to remarkably tough, and several of them have taken root even in the most barren stretches of the wasteland.[320]
  • Several years after buying the Excavator Chip from the Chosen One, Marge LeBarge is able to purchase and control both the Morningstar and the newly opened Kokoweef mines. Marge is an easy choice for Mayor, and using her new political power, she makes Redding join the growing New California Republic in return for a seat in the NCR's Hall of Congress.[321]
  • With the destruction of the conspiracy to destroy the mutants, Broken Hills begins to thrive. Then the uranium ran out. The city, having lost its sole reason for existing, slowly disperses.

A few hold-outs remain, attempting to eke out a pathetic existence, but eventually, they too, disappear.[322]

  • The Chosen One's help with Vault 15 launched the New California Republic's push to civilize its neighbors. Though there were many more obstacles to overcome, the NCR now had a foothold into the northern wastes.[319]
  • Shi eventually went into an uneasy trading relationship with the tanker vagrants after the destruction of the Hubologists, and the two groups went on to make San Francisco a major fishing and trading center.[324]




  • Graham, Calhoun and Sallow are captured by the Blackfoot tribe for ransom. The young Sallow uses his knowledge to train the tribals in the art of warfare, impressing them enough to become their leader.[229]
  • Sallow assumes the name of ancient Roman emperor Caesar and makes Joshua Graham his right-hand man. He decides to create an empire modeled after the historical Roman Empire, intending to erase the tribals' individual identities and replace them all with a single, monolithic culture - the Legion. He tells Calhoun to go back to the Followers and spread the news of these happenings.[229]

They invade Kyle's beloved Bloomfield – Kyle and his men do not resist Dr. Presper and his technically more advanced brigade – and launch themselves into space to dock with B.O.M.B.-001. Four NCR soldiers stay behind with the remaining rocket to prevent anyone from launching the second rocket. The Rusty Hooks keep clear of the launch pad and form an "understanding" with the NCR guards.[110][111]








  • A generator in the Citadel overloads, creating errors in the artificial intelligence routines of the medical robot called Sawbones, giving him intelligence beyond his programming and a disliking for his human masters.[347]
  • Amata Almodovar's mother dies from unknown causes.[348]


















  • Caesar's Legion, the New California Republic and the Society are forced to end their war, signing the New Vegas Concord and creating firm borders for each of the three tribes. An uneasy truce is maintained for the next 50 years.
