Welcome to Megaton. The bomb is perfectly safe. We promise.Deputy Weld

Megaton is a fortified settlement in the Capital Wasteland. It is built in and around a crater with an undetonated megaton class atomic bomb at its center, after which the town is named. The town of Megaton is protected by large metal walls made from various scavenged materials, primarily the scraps of old pre-War airplanes, which were assembled and reforged together several decades ago by the founders of Megaton in an effort to make the town safer. With 28 named inhabitants, 10 unnamed Megaton settlers, and 4 Children of the Atom, it is surpassed only by Rivet City in terms of population.



The site of Megaton began as a gigantic crater left by a plane wreck that was carrying an atomic bomb. Shortly after the crash, several wasteland survivors, including Manya Vargas' grandfather, attempted to gain entry to Vault 101 and huddled down in the crater, since it provided shelter from the dust storms. Once things began to settle down, some people left and began to wander the wasteland. These people then returned later on to trade with the remaining settlers. As a result, Megaton had become a full-on trading center by the time Manya's father was born.

However, as a result of the town's expansion, raids by gangs and super mutants became an issue. Manya Vargas' father became rich on the caravan routes, and convinced the other settlers to construct their homes in the crater using aircraft debris and plane scrap from a nearby airport. Everything had been scavenged from the airport by other wastelanders and all that remained were the planes, which were used in the town's construction, and so the airport no longer remains.

Megaton's construction was aided significantly by the Children of Atom who had just began to worship the undetonated atomic bomb in the town center. The settlers were forced to leave the bomb untouched in exchange for their much needed help.

First contact with Vault 101 and raider attackEdit

As the years went by, Megaton remained a stable settlement. In February 2241, an expeditionary party of Vault 101, led by Anne Palmer and sent by the overseer of the vault, made contact with the residents of Megaton. Initially the locals were cautious of the strangers, but eventually they were accepted and welcomed into the settlement. Palmer appointed two vault residents, Agnes Taylor and Lewis, as vault ambassadors to Megaton and, as a result, remained in Megaton to further study the town and the surrounding environs before eventually returning to Vault 101. A record of this expedition was archived in the overseer's terminal in his office.

During the same year, a group of raiders attacked the town, resulting in the death of 14 year old Colin Moriarty's father. After the raid, Moriarty inherited his father's wealth and his bar, Moriarty's Saloon.


Many residents of Megaton came from the surrounding areas and weren't originally born there. The Stahl family came from the north, Moira Brown came from Canterbury Commons, which is the main source of Megaton's food and supplies and Doc Church came from Rivet City.

Boppo's raidEdit

By 2277 Megaton was still a large settlement and trading center, but still faced common wasteland threats. A gang of raiders who had been occupying Springvale Elementary School launched a raid on Megaton. A group led by Boppo staged the raid on Megaton, but the attack ended abruptly when Boppo was shot in the head and killed by the town's sheriff, Lucas Simms.

However, the raiders did not leave the area, choosing instead to remain at the Springvale school. Boppo's successor recognized the folly of any raid on Megaton, and instead began attempts to tunnel into Vault 101. This plan was terminated when the raiders tunneled into a nest of giant ants.


Megaton had commonly received people who had escaped Vault 101, due to the fact the vault is located very near to the site of Megaton itself. Around 2267, a girl from Vault 101 stumbled into Megaton and had Moira Brown armor her vault jumpsuit for her (though the girl never came back). Moriarty claims to have met an escaped vault dweller in 2272. James, Cross and the Lone Wanderer (as an infant) visited Megaton in 2258 on their way to Vault 101 and stayed in Moriarty's Saloon. 19 years later, James returned to Megaton to speak with Colin Moriarty. The Lone Wanderer (as an adult) entered the town in search of their father, and disarmed the atomic bomb during their visit. Lucas Simms died when the Lone Wanderer alerted him to Burke's plan leading to Burke shooting him in the back, and when drunk, Harden would speak about how the Lone Wanderer was responsible for Lucas' death.[1]

After the Brotherhood-Enclave WarEdit

Following the Brotherhood victory against the Enclave, and the activation of Project Purity and the distribution of Aqua Pura, Megaton slowly rose to a great fame throughout the wasteland, and was instantly put on the map. By 2297, the town became the hub of the Wasteland Survival Guide distribution, and brought in masses of assistants for the town. In addition, Harden Simms succeeded his father in the position of sheriff.[1]


The residents of Megaton feel safe behind their metal walls. Ironic, considering their proximity to a live atomic bomb.Fallout 3 loading screen

The city of Megaton has been built in a steep-walled crater around an undetonated atomic bomb, which rests in a small pond of radioactive water at the bottom of the depression. This gives the city two roughly circular levels centered on the bomb. The main gate consists of two old aircraft wings and is powered by a jet engine, which can be opened and closed to protect the town's only entrance/exit.

Following the entry path to the bottom of the depression, the Megaton clinic will be on the right and The Brass Lantern on the left. Just past the bomb to the right is the Children of Atom building and past it to the left lies Mister Burke's house. Confessor Cromwell will be found here standing in the puddle and sermonizing to random Megaton settlers.

Turning right immediately upon entering and following the lip of the crater counter-clockwise will lead past Lucas Simms' house, around the water processing plant, down to Craterside Supply, then back up to the men's restroom, Moriarty's Saloon and Billy Creel's house. Going down the ramp from there will lead around Nathan and Manya's house (a blue bus) and to the women's restroom. Craterside Supply can also be easily reached by taking the ramp directly to the right of the Megaton clinic.

Turning left instead of right at the upper lip will lead to a locked house (which is a reward from Lucas Simms for deactivating the central atomic bomb and will subsequently be renamed My Megaton House), followed by Jericho's house. From there, going down will lead to Lucy West's house while going around to the left will lead to the end of the right hand path.

The Megaton armory, only accessible by either picking the very hard lock or with Lucas Simm's key, can be reached by going up the ramp and around the Church of the Children of Atom to the right or by going down the hill starting from the back door of Moriarty's Saloon. Inside, the player character will face a strong opponent, Deputy Steel, a unique Mister Gutsy.

The common house can be reached by going around the women's restroom to the right or by passing behind Moriarty's Saloon rather than going around the front past the entrance to the men's restroom. Just look for the couch sitting outside.

In front of the city, outside the walls, is a caravan stop; Micky the water beggar; and Deputy Weld. Behind the city, near the southwest corner, between a group of 3 scorched trees is the hollowed-out rock.

Megaton ruinsEdit

Revisiting Megaton's ruins after blowing it up in The Power of the Atom, the Lone Wanderer will find Deputy Weld's head with an orange (or purple) eye nearby, sticking out of a pile of debris. He says, ironically, "Welcome to Megaton. The bomb is perfectly safe. We promise. Please hold," in a garbled voice that sounds broken. The town will be completely inaccessible, as a high wall surrounds it. The sky will be green.

If the Wasteland Survival Guide quest has been started, Moira Brown will survive as a ghoul and show up to mention that she is relocating to Underworld. If the quest is not started, Moira can still be found in Underworld. If Jericho was hired and is following the player character at the time of the detonation, he will linger around the ruins for later recruitment. Detonating the bomb before retrieving the Strength Bobblehead will render it unobtainable. The area around Megaton will contain progressively higher levels of radiation closer to the town's ruins, up to 11 rads per second. Ground zero (only reachable using tcl) will count 26 rad/s.



Notable lootEdit

  • 300-700 bottle caps in The Brass Lantern. A Very Easy locked terminal unlocks a floor safe which otherwise has a very hard lock.
  • A rolling pin, a rather hard-to-find and (mostly) cosmetic weapon, can be found in the water processing plant.
  • The sheriff's duster and hat are found being worn by Lucas Simms.
  • There are five boxes of Sugar Bombs: One in the Megaton common house to the right of the entrance on a shelf, two in Craterside Supply on the bottom shelf in the northwest corner, one on a shelf in the upper level of Lucas Simms' house against the northeast wall, and one in Lucy West's house upstairs on a shelf across from the bed.
  • There are four teddy bears in Megaton: One is in Billy Creel's house in a box on the table upstairs, two are in Jericho's house to the right of the entrance and under the bed, and one is in Lucas Simms' house upstairs on a table in the southwest room.
  • Schematics - Rock-It Launcher - Sold by Moira Brown
  • Environment suit, armored Vault 101 jumpsuit, shady hat, repellent stick and schematics - bottlecap mine - Can all be obtained by helping Moira Brown with the Wasteland Survival Guide quest.

Related questsEdit


  • This is likely the first settlement the Lone Wanderer will encounter, due to Megaton's proximity to Vault 101 and the fact that Following in His Footsteps, which starts upon exiting the vault, begins with a directive to investigate the town.
  • The Strength bobblehead must be obtained before blowing up the town in the Power of the Atom quest, as the explosion will destroy Lucas Simms' house, rendering the bobblehead inaccessible.
  • If the player character has very good Karma, a Megaton settler will approach each day the Lone Wanderer is in Megaton (after around 8am) and provide a random item of loot, saying a randomized quote, including but not limited to, "I wish there were more people like you in the world." The gift can range from ammunition (around 10 to 20 of any standard type) to medical supplies (stimpaks, Rad-X, etc.) to packaged food. She will sprint from wherever she happens to be in town in order to approach; occasionally this action will not be triggered, but finding and talking to her will produce the appropriate dialogue. With very bad Karma, the same settler will approach and mutter insults instead of providing something.
  • Despite the completion of the Power of the Atom side-quest with the outcome of defusing the live atomic bomb, Megaton Settlers will still be rude to you if you attempt to speak to them. Karma does not affect their speech.
  • Wearing a Vault 101 jumpsuit when entering Megaton for the first time will lead Lucas Simms and the other named settlers to comment on it during the initial greeting. This special greeting does not occur when wearing the vault security, utility jumpsuit or vault scientist coat.
  • Megaton will occasionally be attacked by various enemies when the Lone Wanderer approaches or leaves it. These are usually one or two raiders or giant ants but can be more dangerous enemies such as giant radscorpions. Usually, Deputy Weld can easily dispatch them, with the help of Stockholm and any merchant caravan that may happen to be in front of Megaton when the fight happens.
  • After The Waters of Life quest is complete, an Enclave Vertibird may drop off some Enclave soldiers south of Megaton.
  • Looking up during Megaton's daytime will show a flock of birds circling the settlement.
  • If Megaton is blown up, the fast travel point will be renamed "Megaton Ruins."
  • Viewing Megaton Ruins, an eerie green glow will surround the wreckage, which will still be evident from places like Super-Duper Mart.
  • Megaton cannot be entered after it is destroyed, and getting very close will result in a hefty dose of radiation.
  • The player character will likely encounter Megaton refugees after destroying Megaton; they are hostile on sight.
  • The first time the Lone Wanderer comes to Megaton, the gate is closed, but it opens upon approach. The gate never closes again after this.
  • Even after gaining access to the empty Megaton house, performing various tasks for the locals, and spending a significant amount of time in Megaton, the Lone Wanderer is still considered an outsider by the settlers in their conversations. In fact, nobody besides the Simms' family and Moira comments on anything remotely related to the fact that the Lone Wanderer has a permanent house there.
  • Megaton is an open environment, so fast travel is available into and out of town without going through the town gate.
  • There are additional unused sniper towers seen on the inside perimeter of the town, although they cannot be seen from the outside and there is no visible way to enter them.
  • It is possible to get to Stockholm by entering Lucas Simms' house, going through the trapdoor on the second floor, jumping on the fence on the roof, running along the fence, getting on top of the plane, running along the left side of the plane, and making a jump at the perfect time to land on the city walls. From here, carefully walk along the edge to his platform. Once up, it is possible to talk to him, and he will say he needs to keep his eyes open, and wonder how the Lone Wanderer got up there.
  • The irradiated water source that the atomic bomb is sitting on can be very useful for the second part of the Wasteland Survival Guide quest.
  • Behind Megaton there is a secret weapon stash containing a Stealth Boy and sniper rifle with ammunition.
  • In the Megaton clinic is a holotape that will start the Replicated Man mission. You can also talk to Doc Church and Moira Brown after listening to the holotape to complete the next steps in the mission.
  • The bomb in the center of Megaton is said to have come during the Great War. However, there is some inconsistency with the established lore of the Great War. In the original story itself, it was inter-continental ballistic missiles which created the wasteland, and not bombs. However, it is possible that the bomb itself is a reference to the several bombs lost during the development of the atomic bomb in the US, most notably one which was dropped on a small town in Virginia, but did not detonate. Given the EMP pulse from a nuclear explosion, as well as the shockwaves, it's entirely plausible that the bomb was in transit when the apocalypse came, and fell from its mounting as the aircraft (which Megaton is made of) crashed to earth.
  • A note found near the Museum of Witchcraft in Fallout 4 mentions Megaton, containing the vague statement of "looks like history repeats itself".
  • The Sheriff's duster appears in Fallout: New Vegas and has a sheriff's star with the inscription «Megaton».


Megaton appears in Fallout 3 and is mentioned in Fallout: New Vegas and Fallout 4.

In Fallout Shelter, it is mentioned in the description for Sheriff's duster and as a question in the weekly quest Game Show Gauntlet.

Behind the scenesEdit

  • In Beneath The Planet of the Apes, a cult is featured worshiping an undetonated nuclear weapon after the modern world has been destroyed.
  • A megaton is a unit used to measure the force of an explosion, equivalent to that of a million tons of TNT.
  • In the Japanese version of Fallout 3, Burke is completely gone, and therefore, the quest to blow up Megaton has been completely removed due to its parallels to real historic events,[2] referring to the atomic bombs that were dropped on Hiroshima and Nagasaki in 1945.
