This is what happens to people who fuck with the Brotherhood.— Unnamed Brotherhood of Steel soldier

Fort Bannister is a pre-War military installation in the Capital Wasteland in 2277. It is north of Evergreen Mills and south of Jalbert Brothers waste disposal.


When the Great War came in 2077, it was one of the highest-profile targets in the area,[Non-game 1] suffering a number of direct nuclear hits that obliterated much of its surface facilities, leaving a gaping crater and concrete ruins behind.[Non-game 2] The nuclear detonation did not destroy the bunker's underground installations, however, which was likely the main reason it was secured by Talon Company mercenaries and used as their primary base.[Non-game 3] Its missile silo doors reside in a ruined building.


The bunker itself is extensive and is accessible from the ammunition storage, a manhole inside a commander's tent, a bunker entrance just above the commander's tent, and a metal door down some steps just to the right when entering Fort Bannister through the south gates.

The underground levels of the fort are crawling with hostile Talon Company mercs who are all very heavily armed. If the Lone Wanderer's combat skills are high enough to clear the place out, the area contains a staggering amount of valuable hardware to scavenge. The mercenaries here have a wide range of armaments, including assault rifles, Chinese assault rifles, combat shotguns, laser rifles, flamers, missile launchers and 10mm SMGs.

In the commanding officer's quarters are Commander Jabsco, the leader of the company, a Mister Gutsy (though the Mister Gutsy model may be found in a dormant state, and is likely activated once the player character attacks Jabsco) and two automated turrets. However, the first of these turrets (the one upstairs) can be either deactivated or frenzied via a locked terminal just outside the commander's personal quarters. Although the frenzied turret will track and attack Commander Jabsco, it rarely fires at him when he has a melee weapon armed.

The commander himself starts off with a missile launcher, but once he runs out of ammunition for it, will either attack with his Occam's Razor, pull out his Chinese pistol or rush downstairs and grab any weapon in the nearby safe. There is also a chance that once the player character attacks the commander, more Talon Company mercs will spawn behind them. He will call out for assistance when the conditions for reinforcement have been met. In Commander Jabsco's personal quarters, there are four generators which will explode when shot or sufficiently damaged by explosives.

Broken Steel[]

With the Broken Steel add-on installed, the player should find several Aqua Pura pack brahmin near the tents. When searching the tents, they should also find Brotherhood Paladin Jensen tied up. He tells the player character that the Brotherhood is tired of having their Aqua Pura stolen by Talon Company, and intends to get some payback - Jensen is the scout for the operation.

If the player frees him, he will charge down into the fort, quickly getting himself killed by the awaiting turret and the missile-launching Talon Company merc. Soon thereafter, two to four more Brotherhood of Steel knights and paladins will run in after him. The Talon Company defenses will shortly prove too much for the Brotherhood, and most of them will likely die. Alternatively, it is also possible that the knights will defeat the mercs and occupy Fort Bannister if the player decides to assist them. It will become another BoS outpost soon after.

It is also possible to run into the Brotherhood's Alpha Squad (just south of the fort), which will soon assault the fort, before freeing Jensen or even approaching the fort. They can be convinced to assault the fort before freeing Jensen, who will be freed at some point during the assault.

After The Waters of Life quest, an Enclave research outpost can be found near the large crater, with a field research terminal containing their objective in the area (gathering samples). The camp is occupied by three Enclave soldiers, one Enclave officer and one Enclave scientist. There is also an Enclave turret. There are three Enclave crates and in one of which one can store gear (the crate at eye level, behind the computer terminal). In the crater there are eight alien power cell cartridges underneath the overturned truck. There is a constant low level of radiation (+1/2).

Behind the scenes[]

Level designer Philip Nelson worked on the creation of Fort Bannister.[Non-game 4]


Playstation 3Playstation 3Playstation 3 Xbox 360Xbox 360 If the player kills everyone inside the fort while the Brotherhood are still hiding, there is a chance the Brotherhood will instead make the tents a base, rather than the fort. Even if you don't kill anyone at all inside the fort, they will still occupy the tents. Manage to keep everyone alive on the Brotherhood team, and they still leave the fort after the assault.

  1. Fallout 3 Official Game Guide Game of the Year Edition p.335: "Zone 4: Irradiated Western Plains
    Outside of the D.C. Metro Ruins, this western section of the Wasteland was hit hardest be enemy bombardments 200 years ago, and evidence of the cataclysm is still apparent. Desolate pathways that used to carry vehicles are now used by Scavengers, Raiders, and other ne'er-do-wells. To the west is a large and extremely radioactive "birthplace" of the Super Mutants on this side of the county. To the east are the irradiated plains, where Wastelanders slowly morph into Feral Ghouls. While the Raiders attempt to edge in to the north, this zone is primarily a battle for supremacy between Super Mutants and the Talon Company Mercenaries, who have commandeered Fort Bannister, the epicenter of the historic bombardment. Be careful out there!
  2. Fallout 3 Official Game Guide Game of the Year Edition p.344: "BANNISTER CRATER:
    The massive bombardment of countless nuclear strikes has turned the area to Fort Bannister's east into a hellhole; there are over a dozen large craters near the outer areas of the fort and six separate clusters of ruined buildings to sift through."
  3. Fallout 3 Official Game Guide Game of the Year Edition p.341-342: "FORT BANNISTER
    A main military installation that suffered a direct hit back when the bombs fell is now the headquarters for the Talon Company. From a distance, this place looks like a small refugee camp with tents, but on closer inspection the Talon Company appear and take no prisoners.
