|For the city as mentioned in Fallout Tactics, see Chicago (Fallout Tactics).|
Before the Great War, Detective Nick Valentine together with his fiance Jennifer Lands transferred from the Chicago Police to Boston to assist the Boston Police Department in Operation Winter's End. In addition, the Enclave maintained an outpost in Chicago. In the message Whitley recorded and stored before sending ED-E to Navarro, he requests anyone at the Chicago outpost to give the unit any repairs it needs. It is also where Tommy recovered ED-E, and after pleading with his father, brought it back to his mother's garage for repairs.
Sometime after the defeat of the Master, the Brotherhood of Steel dispatched at least one airship, to track down the remnants of the Unity super mutant threat. The airship crash landed near the ruins of Chicago. The surviving members of the first expedition thrived outside of Chicago. Far from the elders in Lost Hills, a new Brotherhood of Steel chapter was formed.[Non-canon 1] The survivors initially organized themselves into a new detachment, cutting all contact with the larger Brotherhood.
Another expedition was sent east by the Brotherhood of Steel, this time with the destination being Washington D.C. As part of this expedition, contact was to be made with chapters of the Brotherhood in the region. The Midwestern Brotherhood was contacted and confirmed they were still operating out of Chicago, after a recently waged war against a band of super mutants.[Non-canon 1]
In the Commonwealth, the city is mentioned on the holotape Welcome home!, as well as the source of the Skylanes 1981 flight in Skylanes smuggling manifest. An Appalachian resident named Shawn Aaronholt wrote a note that mentions Chicago, and that he disagreed with his brother Lowell about moving there, wanting to head south to settle instead. A note titled Last will and testament written by Lowell also mentions Chicago, in that he wishes he would have gone there. The city is also mentioned as where former astronaut and possible ally Sofia Daguerre lived as a child.
Behind the scenes
Chicago is a real world city of the same name, in the Midwestern United States.
- Whitley: "Subject E: Diagnosis complete. Begin Recording. My name is Whitley. I'm a researcher at Adams Air Force base. Until recently I was in charge of the Duraframe reinforcement project for the combat model Eyebots. Eyebot Duraframe Subject E is both the prototype, and the last functional model in this test group. I was prepared to make several significant upgrades to the machines. However, as the project was canceled and all Duraframe assets are being diverted to Hellfire Armor, I am sending this model to the Navarro outpost. If you are listening to this log from one of our Enclave Outposts in Chicago, give this unit whatever repairs it needs so it can continue to Navarro."
- The Lone Wanderer: "Care to share anything about the Super Mutants?"
Elizabeth Jameson: "The Brotherhood has been battling Super Mutants for decades. First out West, then in Chicago. Now here. But this group of Super Mutants is different, somehow. Physically, yes, but mentally as well. If we knew where they came from, we'd know why."
(Elizabeth Jameson's dialogue)
- The Courier: "Sounds like that kid was pretty fond of you. Why did you leave?"
The Courier: "Where did this happen?"
The Courier: "Illinois? So that's where you got that plate. The other you, I mean."
The Courier: "What's a Chicago?"

Brotherhood soldier (1): "I still can't believe I was posted to the Prydwen. I mean, look at her... she's one of a kind."
Brotherhood soldier (2): "Actually, the Brotherhood of Steel had a whole fleet of these things at one time. They weren't as advanced as the Prydwen, mind you... but seeing them fill the sky must have been an impressive sight."
Brotherhood soldier (1): "Are you kidding me? What happened to them?"
Brotherhood soldier (2): "Not sure, really. Most of them were destroyed fighting Super Mutants or scuttled for parts. I think one of them crash landed somewhere in the Midwest. I heard that the wreckage is still there."
Brotherhood soldier (1): "Wow... I had no idea."
- The Sole Survivor: "Did the Brotherhood ever build other airships?"
Kells: " "
- The Lone Wanderer: "Then where's the rest of the Brotherhood?"
Reginald Rothchild: "The West Coast, unless something has changed. There's been no contact with them for the last several years. There's also a small detachment in Chicago, but they're off the radar. Gone rogue. Long story."
(Reginald Rothchild's dialogue)
- Welcome home!
- Skylanes smuggling manifest
- Shawn's journal: "John and I are sick of hearing Lowell talk about Chicago all the damn time. Lowell wants us to pack up and head that way. Who gives a shit about Chicago? I always thought we should travel more south to see if any of our cousins survived."
- Lowell Aaronholt's last will and testament
- Fallout 3 Official Game Guide Game of the Year Edition p.71: "Elder Owyn Lyons
Lyons, 75, was already highly decorated when he set out from the order's West Coast headquarters, leading a party of soldiers on a mission to reestablish contact with the 'Eastern Brotherhood.' He discovered this abandoned Pentagon military complex. The presence of Super Mutants sent a chill up the collective spine of the Brotherhood; these weren't the children of the dreaded Master, nor were they the remnants of the band that fled east and were ultimately destroyed (or assimilated into the Brotherhood of Steel) in the Chicago area. No, this was a new breed of Super Mutant, one with a local origin. But where did they come from? What did they want? How were they reproducing? Elder Lyons was ordered to discover the source of this new Super Mutant infestation and wipe it from the face of the earth. Recent weeks have seen him galvanize his 'Pride' to thwart the remnants of the Enclave forces, and to provide drinking water to all."
