Episode 1: The Great War
The Fallout 4 walkthrough starts on October 23, 2077, as the bombs fall and the Sole Survivor is frozen in Vault 111. After waking 210 years later, we escape the vault, return to Sanctuary Hills, recruit Dogmeat at Red Rocket, and meet the Minutemen in Concord.
The first major set piece is the T-45 power armor and the Concord deathclaw. After that fight we get pulled into Thicket Excavations before the Commonwealth really opens up.
Episode 2: ArcJet Synths
Episode 2 expands both the Minutemen and the Brotherhood of Steel. We hit Skylanes Flight 1981, help Tenpines Bluff, and clear the raider infestation inside the Corvega Assembly Plant in Lexington.
Mama Murphy’s vision sends us back on the road. Military Frequency AF95 leads to Cambridge Police Station, Paladin Danse, and Call to Arms. The episode ends inside ArcJet Systems, fighting synths for the Deep Range Transmitter.
Episode 3: The Lost Patrol
After reporting back to Danse, we clear College Square, claim Taffington Boathouse, grab a fusion core from Malden Drainage, and fight through West Everett Estates, including the super mutant boss Hammer.
The rest of the episode is The Lost Patrol. We follow Brotherhood distress beacons to Knight Varham, Knight Astlin at the National Guard Training Yard, and Scribe Faris at the Revere Satellite Array. At Recon Bunker Theta, Paladin Brandis is killed on sight before we report back to Danse.
Episode 4: Storming The Castle
The Minutemen keep expanding. We clear Beantown Brewery, help Oberland Station, wipe out Back Street Apparel, set up Sunshine Tidings Co-op, and fight through Easy City Downs against Eager Ernie and Iron Maiden.
Taking Independence is the climax. After stops at Mass Fusion and Goodneighbor, we meet Preston at The Castle, fight waves of mirelurks, and kill the Mirelurk Queen to retake Minutemen headquarters.
Episode 5: Kellogg & Fort Hagen
We finally reach Diamond City, meet Piper, and get sent to rescue Nick Valentine. Park Street Station and Vault 114 are a full triggerman dungeon ending with Skinny Malone and Darla.
Nick helps break into Kellogg’s house. Dogmeat tracks the mercenary to Fort Hagen, where we fight synths, grab a Fat Man, and kill Kellogg. Leaving the fort triggers the Prydwen’s arrival over the Commonwealth.
Episode 6: The Memory Den
The search for the Institute moves to Goodneighbor. Inside the Memory Den, Irma and Doctor Amari use Kellogg’s cybernetic implant, with Nick Valentine hosting the memories.
The lounger sequence walks through Kellogg’s past and confirms there is no surface entrance to the Institute. The next target is Doctor Brian Virgil, hiding in the Glowing Sea.
Episode 7: Assaulting Fort Strong
We return to Cambridge Police Station, board a Vertibird, and reach the Prydwen. Elder Maxson, Lancer-Captain Kells, and official Brotherhood power armor mark the formal induction.
Show No Mercy sends us to Fort Strong. After gunning down a Super Mutant Behemoth from the air, we clear the armory and later recover Mary’s locket from USAF Satellite Station Olivia for Abernathy Farm.
Episode 8: The Nakano Case & Far Harbor
Ellie Perkins gives us the Nakano case. At the Nakano residence we find Kasumi’s holotape, learn she contacted a synth colony to the north, inform the Brotherhood, and sail to Far Harbor.
The island intro covers the fog, the harbor defense, Old Longfellow, and the first push toward Acadia.
Episode 9: Acadia & The Nucleus
Inside Acadia we meet DiMA and Kasumi Nakano, steal Faraday’s Program holotape, and confront DiMA with the evidence. The Children of Atom are next.
The road to The Nucleus runs through Pine Crest Cavern and the fog. Visions in the Fog requires drinking from Atom’s Spring, following the Mother of the Fog, and recovering the Mother Icon so Grand Zealot Richter will let us inside.
Episode 10: Destroying The Nucleus
Faraday’s program points to Avery’s grave at the Vim! Pop Factory and DiMA’s secret. After confronting him in Acadia, we commit to Cleansing the Land.
The nuclear launch key is recovered from a submerged safe at Fringe Cove Docks. We insert it in The Nucleus, escape the detonation, wipe out the remaining Children of Atom, and debrief DiMA.
Episode 11: The Glowing Sea & Hunter/Hunted
The Glowing Sea crossing runs past mirelurks, the Mass Fusion Disposal Site, and the Crater of Atom. Isolde points us to Virgil’s rocky cave, where the rogue scientist explains that a Courser chip is required to reach the Institute.
Hunter/Hunted then sends us through the CIT Rotunda and Greenetech Genetics. We kill the Courser, take the chip, and free the captive synth K1-98.
Episode 12: The Molecular Level
Doctor Amari sends us to the Railroad to decipher the Courser chip. We follow the Freedom Trail to Old North Church, enter Railroad HQ, and have Tinker Tom work on the chip.
Choosing Brotherhood help, we build the Signal Interceptor with Proctor Ingram, recover the remaining parts, and finish The Molecular Level.
Episode 13: Institutionalized
The teleporter reaches the Institute. The first meeting with young Shaun is a decoy. The real Shaun is Father. After speaking with the division leaders and Doctor Li, we retrieve Bioscience evidence and convince Li to return to the Brotherhood.
The episode then starts the Liberty Prime rebuild and reports back to Maxson and Ingram.
Episode 14: Synth Retention & The Battle of Bunker Hill
Father assigns Courser X6-88 for Synth Retention. The coastal route runs through Reeb Marina, Gibson Point Pier, Lynn Pier Parking, and Nahant Sheriff’s Department before the fight for Gabriel on the Libertalia tanker.
The Battle of Bunker Hill then pits the Institute, Railroad, and Brotherhood against each other. We meet X4-18, deal with the escaped synths, and finish on the CIT roof with Father.
Episode 15: Mass Fusion & Powering Up
At the Directorate meeting Father names us his successor and reveals that he is dying. Relaying to Mass Fusion is the point of no return and makes the Brotherhood a permanent enemy. We recover the Beryllium Agitator from the reactor, then complete Pinned by taking T.S. Wallace by force.
Powering Up finishes the episode. We record the Institute broadcast, reconfigure Diamond City Radio, install the agitator, and start the Institute reactor.
Episode 16: Airship Down & The Institute Ending
The Directorate orders the destruction of the Railroad. We teleport to Old North Church, wipe out Railroad HQ, and escape through the tunnels.
Airship Down is the Brotherhood finale. After speaking with Evan Watson, we infiltrate Boston Airport, destroy the generators, defend the synth hacking Liberty Prime, and watch the Prydwen fall. Nuclear Family then ends the game with Father’s last conversation and the Institute ending.
