The Super-Duper Mart and the first Wasteland Survival Guide quest that accompanies it were likely thought up after an electrical storm knocked power out for 8-10+ hours in the Bethesda studio. Todd Howard and several other staff members went to a local Supermarket, using an iPhone to light their way across the pitch-dark aisles and essentially began to brainstorm ideas from that experience.

When talking to Milo, the shipping foreman of the Nuka-Cola Plant, asking for the shipping manifest and will result in him giving the player the terminal pass-code, NC-C1864. This is the registry number for the USS Reliant in the movie "Star Trek: The Wrath of Kahn".

The 2008 E3 trailer for the game contains a Vault-Tec commercial which advertises a phone number. Calling the 1-888-4VAULT-TEC number will play an automated message saying:

When creating the gun-system for Fallout 3, one of teams first tests was taking a bow from Oblivion and making a Bow and Arrow "gun." It shot rapid-fire arrows and apparently "didn't work quite right", so the new gun-system for the game was built up from scratch.

Actress Courtney Cox, best known for playing Monica Geller from the TV sitcom "Friends", briefly worked for Bethesda in the 1980s. She (along with David Arquette, Odette Yustman, Ben Harper and the Zenimax board of directors) later helped host the Fallout 3 launch party on October 18, 2008.

The voice of the protagonist as a baby is actually Game Director Todd Howard's son, Jake Howard.

The drug "Med-X" was originally just called Morphine, but in order to get a MA15+ rating in Australia by the Office of Film and Literature Classification (OFLC) board, all references to Morphine had to be changed to "Med-X". During the time there was no higher age rating (R18+) for video games, which would have meant the game could not be sold in Australia. The reason the OFLC board didn't pass the game was because of the usage of real-life drugs.

While the V.A.T.S. targeting system is an evolution of the targeted shot mechanic in earlier Fallout games, the slow-motion visuals were inspired by the Crash Mode Replays from the Burnout series. Artist Grant Struthers prototyped the V.A.T.S. camera system by filming stop-motion fight scenes with his Incredibles action figures.

Sally from the Mothership Zeta DLC makes references to a fictional pre-war show called 'Captain Cosmos', which itself features classic Star Trek references, such as "All systems normal, Captain!" and "Captain on the bridge!"

She also mentions a female 2nd officer, saying "Stella Skyfire reporting for duty! She's Captain Cosmos' second in command, at least for the first few episodes..."
This is in reference to the original, unaired pilot episode of Star Trek: The Original Series, "The Cage", in which Captain Pike has a female lieutenant who is second-in-command, simply referred to as "Number One". NBC rejected this pilot and requested a new pilot episode, ultimately making her role as second officer last for only one episode.

Another notable reference is the time slot 'Captain Cosmos' airs at, which was Thursdays at 8:00PM EST, according to leftover posters in the Hubris Comics building. Star Trek:ToS aired on the same day but at 8:30PM EST.

Just outside of Big Town, there is a utility pole in the exact center of the game map with a unique plate that reads "TES-04."

This is a reference to The Elder Scrolls IV: Oblivion, also by Bethesda. The placing of this pole in the map center likely suggests a reference to TES IV's most notable landmark, the White Gold Tower, which is considered to be the central point of the continent of Tamriel as well as the Imperial Empire in The Elder Scrolls games.

In the Hubris Comics building is a letter to an editor on the receptionist's computer which includes a number of comic book references.



"Mr. Moorellis" is likely the combined last-names of Alan Moore and Warren Ellis, two well known English comic book writers.
"Mr. Neptura" is a reference to the character "Marto Neptura" in the comic Promethea, which was written by Alan Moore.

After Spoiler: blowing up Megaton and encountering Moira after she becomes a ghoul, one of the player's dialogue options is "Honey, you got reeeal ugly!" This is a reference to Evil Dead 3: Army of Darkness, where Ash says this to Sheila.

Originally, President John Eden was meant to be voiced by former president Bill Clinton, but the team was unable to get him for the role.

Through the use of cheats, it is possible to talk to Stockholm (the guard on top of the megaton entrance) who is usually inaccessible. When talked to, he will state:

In the Slaver Barracks of Paradise Falls, there is a Vault 77 Jumpsuit, with a Holotape right next to it. The Holotape is from a slaver who wants someone else to get rid of the jumpsuit that "a stranger with no name" left behind. The man recording the holotape is obviously scared and says the jumpsuit "freaks the boys out" so they must fear the stranger. The Vault 77 jumpsuit is the only one in the game and gives you a +5 to both unarmed and melee weapons.

All of these are referencing the Penny Arcade web comic "One Man, and a Crate of Puppets," which starred an unnamed Vault Dweller who was the only resident of Vault 77 and ended up hunting and killing Slavers with his bare hands and a Vault Boy puppet.

Fallout 3 was originally being developed around the early 2000s by developer Black Isle Studios under the codename Van Buren. The game was an RPG similar to the previous installments played from a top-down view and would've used the engine from the canceled "Baldur's Gate III: The Black Hound". The game would've been set in the southwest of America and the story focused around a prisoner who escapes from prison and trys to discover why he was there in the first place and to stop a scientist named Presper from unleashing a virus to cleanse the world of non-pure blood humans. The project was canceled after Interplay had laid off the development team, however a tech demo was later leaked onto the internet.

Fat Man was the codename for the atomic bomb that was detonated over Nagasaki, Japan by the United States on August 9, 1945. Because of its relation to the real historic event, the weapon was renamed to the Nuka Launcher in the Japanese version of Fallout 3. It is, however, still referred to as the Fat Man in dialogue.

The "Experimental MIRV" (a unique Fatman) costs more to fire once than it costs to repair a regular Fat Man twice. At several hundred caps per nuke and firing eight nukes per shot, this is the most expensive weapon in the game, albeit the most powerful. It's also one of most inefficient, unnecessary, and impractical weapons in the game.

The Brahmin in all the Fallout games is in reference to "Brahmin" in Hindu culture, and the name likely plays on Hindu culture's reverence for cows.

However, this (and the fact that you and other NPCs can kill and eat the mutated cows) was viewed as disrespectful, which led to Fallout 3 being banned in India.

Liberty Prime is loosely modeled after Gort, from the 1951 movie "The Day the Earth Stood Still."

The "Prime" in Liberty Prime is actually NOT an intentional reference to Optimus Prime from the Transformers, as many people suspected.
