Released worldwide on November 10, 2015, it is the fifth major installment in the Fallout series. The game is set within an open world post-apocalyptic environment that encompasses the city of Boston and the surrounding Massachusetts region known as "The Commonwealth". The main story takes place in the year 2287, ten years after the events of Fallout 3 and 210 years after "The Great War" that caused catastrophic nuclear devastation across the United States. The story begins on the morning of October 23, 2077 at the player character's home, Sanctuary Hills, with the player character, their spouse (Nate or Nora depending on the player character's gender), their son Shaun, and their robotic butler, Codsworth. As the player character is preparing for an event at the Veteran's Hall in Cambridge, a representative from Vault-Tec comes to inform them that their family is approved for admittance into Vault 111, the local fallout shelter. Moments later, a news bulletin warns of an incoming nuclear attack, prompting the family to evacuate to the Vault. They enter just as the nuclear bomb explodes. Upon entering the Vault, the player character and their family are tricked into entering cryogenic tubes by the Vault-Tec staff and frozen alive. After an unknown period of time, the player character and their spouse are re-awakened by two strangers, and the player witnesses Shaun's kidnapping and their spouse's murder. The player is put back into cryogenic sleep, but manages to get free themselves when the life support system malfunctions. The player discovers that they are the sole survivor of Vault 111, and vows to avenge their spouse's death and find Shaun. The player character, known as the Sole Survivor, heads home to find Sanctuary Hills in ruins. The Sole Survivor meets a distraught Codsworth, revealing that 210 years have passed since the war. Codsworth suggests that the player character to go to Concord for help, on the way, finding and befriending a German Shepherd named Dogmeat. When the Sole Survivor arrives at Concord, they rescue Preston Garvey—one of the last of the Commonwealth Minutemen—and his band of settlers from a group of raiders. After assisting Garvey and his group, the player is recommended to travel to Diamond City, a fortified settlement based in the ruins of Fenway Park, where they meet Piper, an intrepid reporter. From there, they learn about a secretive organization called the Institute, terrifying the Commonwealth, kidnapping people from their homes and sometimes replacing them with "synths," synthetic human beings indistinguishable from real humans.The Sole Survivor seeks out Nick Valentine, a detective based in Diamond City, to locate their son, but soon learns that Valentine went missing two weeks previously. After finding Valentine—who is revealed to be a second-generation synth; a sophisticated biomechanical android—the Sole Survivor uncovers the identity of their spouse's killer, a man named Conrad Kellogg. The Sole Survivor tracks down Kellogg and learns from him that Shaun is currently in the Institute. The player kills Kellogg, avenging their spouse's murder, and retrieves a cybernetic implant from his brain, then heads to Goodneighbor to seek help from Doctor Amari—a scientist skilled in neuroscience—to access the dead mercenary's memories. During their hunt for Kellogg, the Survivor also witnesses the Brotherhood of Steel arriving in the Commonwealth with the Prydwen, their mobile airship headquarters, and has the option to travel to Boston Airport to offer their assistance to the Brotherhood in the fight against the Institute. After viewing Kellogg's memories, the Sole Survivor is then tasked to go to the Glowing Sea—the ground zero of the nuclear blast shown early in the game—to find Brian Virgil, an ex-Institute scientist, to get help infiltrating the Institute. According to Virgil, the only way to enter or exit the Institute is with a teleportation chip that only Institute Coursers—trained synth killers—possess. The player must then track down and kill a Courser in order to obtain the chip...
