Sole Survivor



The Sole Survivor is the player character and main protagonist in Fallout 4. Depending on the player's gender selection, the Sole Survivor is either the husband or wife in a pre-War family and has a son, Shaun.

Background
Depending on player choice, the Sole Survivor is either a male retired Army veteran or a female graduate from law school.

According to pre-war records of the Lookout at the USS Constitution, the husband served in the 2nd Battalion, 108th Infantry Regiment, while the wife was a lawyer. At some point during the Sino-American War, the Sole Survivor married and had a son, named Shaun and bought a robotic butler named Codsworth. On October 23rd, 2077, the Sole Survivor was preparing for an event at the Veteran's Hall when a Vault-Tec representative approached the family and approved them for the papers that allowed them access into Vault 111. Only a few moments later, it was announced by a newsreader that nuclear detonations were being reported, forcing the Survivor and their family to rush to Vault 111. They were then trapped in cryogenic stasis under the pretense of being "decontaminated." The Sole Survivor is kept in this state from 2077 to 2287.

In 2227, the Sole Survivor and their spouse are reawakened by two seen unknown individuals and one off-screen, who open the spouse's cryogenic tube with the intent of kidnapping Shaun. Though conscious, the Sole Survivor is trapped in their tube and are powerless to do anything but watch their spouse being shot and their child abducted. The Sole Survivor is re-frozen, awakening in 2287 and escaping the cryogenic tube. Learning that they are the sole survivor of Vault 111, the Sole Survivor emerges from the Vault and vows to avenge their spouse's death and locate Shaun.

Story
The main story of Fallout 4 directly follows the Sole Survivor's actions. {{Collapsible content|

Returning Home
The player character heads home to Sanctuary Hills, now ruined from the bomb blast, where they meet a distraught Codsworth, revealing to the Survivor that over 210 years have passed since they were frozen in the Vault, also telling the player character to go to Concord for help. The Sole Survivor then meets Preston Garvey - one of the last of the Commonwealth Minutemen - and assists him in protecting settlers from a group of raiders and a Deathclaw, later helping them to travel to, and settle into the remains of Sanctuary.

The Search For Answers
After helping Garvey and his group, the player is instructed to go to Diamond City, a settlement based in Fenway Park where they meet Piper Wright, the city's reporter, who tells the player character to seek out the city's detective Nick Valentine who is revealed to have been missing two weeks prior to the Sole Survivor's arrival in Diamond City. After finding Valentine, they learn the identity and location of their spouse's killer, a man named Conrad Kellogg. Tracking him down, Kellogg reveals that Shaun is in The Institute, a secretive organization feared by the people of the Commonwealth, that is based below the ruins of the Commonwealth Institute of Technology. The player then kill Kellogg and retrieves a cybernetic implant from his brain. After some consultation with Nick and Piper, they head to Goodneighbor where they first encounter John Hancock, the self-appointed ghoul mayor of the town, and get help from Doctor Amari, a scientist skilled in neuroscience. The doctor assists the Sole Survivor in viewing the dead mercenary's memories and discovering that the Institute uses teleportation as the means of travel between their facility and the surface. During their hunt for Kellogg, the Survivor also witnesses the arrival of the Brotherhood of Steel in an airship called The Prydwen, their mobile airship HQ.

The Threat Within
After viewing Kellogg's memories, the player is then tasked to go to the Glowing Sea - the ground zero of the nuclear blast during the intro sequence - to find Brian Virgil, an ex-Institute scientist specialized in researching the FEV virus, who has escaped and went into hiding, to get help in infiltrating the shadowy organization. Virgil, now mutated into a super mutant by prolonged FEV exposure, mentions that the player must kill an Institute Courser - one of the most advanced creations of the Institute, designed to be stronger, faster and smarter than average human beings - to get a special chip from it in order to access the Institute. Once the chip is retrieved, the player is directed to find The Railroad, a secret organization that works to free synths from the Institute's control and give them normal lives in the Commonwealth, since only one of its members, Tinker Tom, can decode the chip and get the frequency code used by the Institute to teleport.

A Meeting Long Overdue
The player then heads back to Virgil, who gives them a blueprint of a device that hijacks the frequency of the Institute's Molecular Relay. After retrieving the blueprints, the player must seeks assistance from one of the three factions: the Minutemen, Railroad, or the Brotherhood. Once the device is built, the player infiltrates the Institute to find their son. After finding a synth based on a young Shaun, it is revealed that the real Shaun was kidnapped in 2227, sixty years prior to the Survivor's release from cryogenic sleep, and is now an old man, entitled Father, and the current leader of the Institute.

The Fate of Humanity
From now on the Survivor faces a choice that will greatly affect the Commonwealth and its people. They can side with Shaun and help the Institute in "protecting" the Commonwealth by destroying the Railroad and the Brotherhood of Steel (The Minutemen can be persuaded to ally with the Institute after passing a few difficult speech checks). They can inversely side against Shaun by assisting one of the factions; the Railroad in destroying the Institute and the Brotherhood in order to free and protect the synths; the Brotherhood of Steel in destroying the Institute and the Railroad in order to exterminate all synths; the Minutemen in destroying the Institute (and the Brotherhood of Steel if made hostile to the player) in order to protect the Commonwealth. Either of the four choices results in Shaun's death, this being due to either the cancer he'd developed by then, or by the Survivor's hand.

At the very end, the synth child Shaun will refer to the Sole Survivor as its parent and asks them if he can go live with them anywhere in the Commonwealth to be a family.If the protagonist agrees, the synth child then gives the player character a holotape from the real Shaun with a message that differs depending if the player sides with the Institute or not. In the holotape, the real Shaun tells his parent that he wishes them would give the synth child a chance to live as a family since Shaun himself never had the chance to with the Sole Survivor. The Sole Survivor then contemplates on the events that transpired and says that "This isn't the world I wanted, but it's the one I found myself in" and that they are now ready for anything comes ahead because they know that "War. War never changes." }}
