Megaton

 is a sprawling settlement south of Springvale and west of Grayditch, set in a crater and surrounded by impenetrable walls. It features a sliding front gate - guarded by a sniper named Stockholm and a Protectron named Deputy Weld - and is one of the two largest civilian settlements in the Capital Wasteland.

Megaton should be the first populated town the player encounters after leaving Vault 101. Its proximity to Vault 101, its distinctive silhouette, and the relatively straight route make it extremely difficult to miss, and it will very likely be the first trace of civilization the Lone Wanderer encounters.

Origin and history
Megaton was built by a large group of people who originally planned to seek shelter in Vault 101 but were denied access. So without shelter, they sought refuge in a large crater made by a large commercial plane crashing into the ground, probably as a result of the electromagnetic pulses generated by a nuclear detonation. They then constructed a place to call home out of pieces of metal/aircraft found nearby at a decimated air station. They were aided by the Children of Atom, who worshiped the undetonated bomb in the crater they were building around.

The plane
The large plane still can be seen in pieces throughout the town. The cockpit and nose cone are built into Craterside Supply apparently housing inaccessible living space to Moira. The main section of the fuselage is used as the armory, and the rear end of the plane is on the roof of Lucas Simms' house providing an extra sniper nest and speculated residence to Stockholm. You can get there via a trap-door in the ceiling of the Sheriff's house. The wings make up the two large "fins" that are symmetrically aligned next to Megaton's main gate, and the two engines are separated. One is used to work the pulley mechanism for the main gates, and the other one is above the path to the common house providing breeze.

Location layout
Megaton is roughly circular, with a central plaza around an atomic bomb resting in a puddle of radioactive water. Starting in the north and proceeding clockwise, the plaza is ringed by The Brass Lantern, Mister Burke's House, Children of Atom, and Megaton Clinic. Pathways lead from the plaza to the gate of Megaton, Craterside Supply and the Common House. A major attraction of the plaza are the sermons of Confessor Cromwell.

Around the central buildings, a ring of buildings is built higher up in the crater. The Water Processing Plant and Moriarty's Saloon can be found here along with most of the inhabitants' private houses.

Destroyed Megaton
If you choose to destroy the town in The Power of the Atom, Megaton will be nothing but rubble.

You can find Moira Brown here; she apparently survives the explosion, as she was out in Springvale, but the massive amounts of radiation from the explosion turned her into a ghoul. You can later find Moira in Underworld. Strangely, Deputy Weld also partially survived, but is buried and only his head is visible. He can speak to some extent, and claims that the bomb in Megaton is "perfectly safe".

The explosion also has an effect on the surrounding area in another way - while it is strangely not very radioactive, the massive amount of dust in the zone kicked up by the nuclear blast more or less permanently fogs the area with a green hue. The closer to the center of Megaton you walk, the more radiation is encountered. Radiation peaks at strangely low value: 23 rad/sec.

The shattered remnants of Megaton itself are normally inaccessible. On the PC, it is possible to use console commands to again access to the the remains of Megaton. Fast travel to Megaton Ruins, then enter the console command, then go into the ground, you should see a drainage grate that says it goes to Megaton. Enter this and you will be taken to the version of Megaton as it was before the detonation of the nuke. An alternative method to do the same thing is to type and that brings you to Megaton also. If you do this then the only NPCs you will encounter are a few settlers near the bomb and a Brahmin.

Also you may find some survivors from megaton in the Wasteland(confirmed on Xbox 360, PS3 and on PC in multiple areas), they are hostile against the PC.

Trivia

 * The power of nuclear weapons are measured in megatons.


 * Megaton is likely based on an "old west" theme. Many elements of this are observed in the town such as a sheriff (with a cowboy hat) and deputy, a saloon, a general store, and many outlaws and brahmin (cattle) ranchers.

Bugs

 * There may be a random spot on the Megaton gate from the inside where blood is shown to be gushing as though you were shot. If you fast travel or travel back to the location, it will still be there. (Confirmed XBox 360)


 * There is a bug where the praying Confessor Cromwell will die unexpectedly. His death does not affect any quest. (confirmed PC)


 * If you bring a follower into Megaton and start jumping from level to level, there is a possibility that they will also jump and fall to their deaths (confirmed XBOX 360).


 * There is also a glitch where if you kick a metal barrel at a NPC, he or she will die unexpectedly and will also hurt you. This doesn't do anything to karma though if you talk to any of the megaton settlers, they will treat you as though you have bad karma. (confirmed xbox 360)


 * Sometimes when entering Megaton for the first time Mr. Burke will be found near the atomic bomb. He floats in the sitting position moving toward the walkway leading to the saloon. Once he passes the post holding up The Brass Lantern's canopy he reverts to the normal walking animation. You can talk to him normally and even receive the Fusion Pulse Charge from him needed for The Power of the Atom. If you immediately give this charge to Simms before Burke gets to the saloon Simms runs over to the saloon, passing Burke. He enters, leaves, and finds Burke, but as soon as he starts the conversation he simply falls down dead. (Confirmed XBox 360)


 * Sometimes all the characters there will have their weapons drawn but act normally. (Confirmed 360)

Megaton Bug Fixes (Patch 1.1)

 * As of the December 15th, 2008 (PS3) and January 13th, 2009 (Xbox 360/PC) releases of the Fallout 3 patch, the issues regarding unexpected NPC disappearances and deaths have been fixed. Upon entering Megaton, if they haven't died previously, you should now be able to find all of your missing NPCs including the biggest offenders, Walter, Billy Creel, Colin Moriarty, and Andy Stahl.

Japanese version
In the Japanese version of Fallout 3, the quest to blow up Megaton has been completely removed due to its "parallels to real historic events" quotes Official Xbox Magazine. They are referring to the atomic bombs that were dropped on Hiroshima and Nagasaki in 1945.
