You stumble into Hidden Valley, sand scratching at your combat armor, and you expect to find the legends. The guys from the capital wasteland. Instead? You find a bunch of paranoid techno-fetishists hiding in a hole because they’re terrified of the sun. Honestly, the FNV Brotherhood of Steel is one of the most tragic, frustrating, and deeply layered factions Obsidian ever put to paper. They aren't the heroes. They aren't even the secondary protagonists. They are a relic.
Most players coming from Fallout 3 expect the Lyons' Pride—knights in shining armor saving the day. Forget that. The Mojave chapter is a dying beast. They’re stuck in a loop of their own making, and if you don’t intervene, they’re basically destined to flicker out like a spent fusion core. It’s grim. It’s claustrophobic. And it’s exactly why they’re the most interesting version of the Brotherhood we’ve ever seen.
The Helios One Disaster: Where it All Went South
To understand why the FNV Brotherhood of Steel is so messed up when you find them, you have to look at Helios One. This wasn't just a lost battle. It was a slaughter. Elijah, the former Elder who was—let’s be real—totally unhinged, obsessed over the Archimedes orbital laser. He stayed too long. He forced his knights to hold a position that was tactically impossible against the New California Republic's sheer numbers.
The NCR has bodies to throw. The Brotherhood has gear. But gear breaks.
When the dust settled, the Brotherhood had lost more than half their fighting force. They retreated to the Hidden Valley bunkers and slapped on a lockdown that has lasted for years. They’re effectively self-interred. When you finally track them down, you’re greeted by a pulse collar and a lot of pointing guns. It’s not a warm welcome because they are quite literally waiting to die of old age or internal strife.
McNamara vs. Hardin: A Tale of Two Bad Options
The internal politics of the Mojave Chapter are a mess. You’ve got Elder McNamara on one side. He’s cautious. Some would say he’s a coward, but he’s really just trying to keep the lights on. He knows that if they stick their heads out of the bunker, the NCR will find them and finish the job. He’s the one who initiated the lockdown.
Then you have Head Paladin Hardin.

Hardin is a traditionalist in the worst way. He thinks McNamara is violating the Codex by not being aggressive enough. If you help Hardin overthrow McNamara, you get a more "classic" Brotherhood experience, but you also seal their fate. Hardin won’t negotiate. He won't compromise. He’ll lead them into one last glorious, stupid charge that ends with the bunker being a tomb. It’s a classic Obsidian choice where there isn't really a "right" answer, just different shades of failure.
Why Everyone Wants the FNV Brotherhood of Steel Dead
If you’re playing the main quest, you’ll notice a recurring theme: everyone hates these guys. Mr. House wants them gone. Caesar wants them gone. Even the NCR, who technically signed a treaty with them back west, wants them neutralized. Why? Because the FNV Brotherhood of Steel are "technological terrorists," as House puts it.
They don't want to rule. They don't want to tax you. They just want your laser rifle.
They believe that humanity is too irresponsible to own advanced tech, so they hoard it. In a world trying to rebuild—like the NCR with their farms or House with his Securitrons—a group of guys who show up and steal your power tools at gunpoint is a massive liability. They are a roadblock to civilization. That’s the tragedy of their ideology. By following the "Codex" to the letter, they’ve made themselves the enemy of every single person trying to make the wasteland better.
The Veronica Factor
You can't talk about this faction without mentioning Veronica Santangelo. She’s your window into the heartbreak of the organization. She sees the writing on the wall. She knows that if they don't start recruiting from the outside—if they don't start helping people—they will inbreed and disappear.
Her personal quest, "I Could Make You Care," is a masterclass in frustration. No matter what proof you bring back to the Elders—whether it's a pulse gun or data on better farming techniques—they dismiss it. They are literally looking at a solution to their extinction and saying, "No thanks, the book says we shouldn't." It’s infuriating. It makes you want to shake them.

The Gear: T-51b and the Power Armor Problem
Let’s talk shop. If you’re siding with the FNV Brotherhood of Steel, you’re doing it for the Power Armor. There’s no other reason. In New Vegas, Power Armor requires a specific perk that you can only get from the Brotherhood (or Arcade Gannon’s questline, but that’s a whole different headache).
The T-51b is the gold standard here. It’s got better durability than the T-45d and looks way cooler. But here’s the kicker: wearing it makes you a target. In the Mojave, faction armor is a real mechanic. If you walk into an NCR camp wearing Brotherhood-marked T-51b, they will shoot you on sight. You’re wearing a walking tank, sure, but you’re also wearing a "kick me" sign for the largest army in the game.
- T-45d Power Armor: Easier to find, lower DT (Damage Threshold), weighs a ton.
- T-51b Power Armor: The classic look, high DT, much harder to maintain without the Jury Rigging perk.
- Remnants Power Armor: Technically not Brotherhood (it’s Enclave), but it’s the only thing that outclasses the Brotherhood’s kit.
Most players rush the Brotherhood quests just to get the training. It’s a slog. You have to find three missing patrols, deal with a scout situation, and potentially crawl through a radioactive vault just to get McNamara to trust you. Is it worth it? For the Gauss Rifle and the DT, yeah. For the company? Probably not.
How to Actually Handle the Brotherhood
You have three real paths when dealing with the Mojave chapter.
First, the "Wipe Them Out" approach. This is what House and Caesar demand. You have to find the three keycards (held by McNamara, Hardin, and Taggart) or have a high enough Science skill to hack the terminal and trigger the self-destruct. It’s a frantic, violent escape as the whole bunker turns hostile.
Second, the "Status Quo" approach. You finish their chores, keep McNamara in power, and they just... exist. They don't help in the final battle unless you specifically broker a truce between them and the NCR.

Third, the "Truce." This is the "best" ending for them, but it’s hard to pull off. You need McNamara in power. You need to be far enough in the NCR questline. If you pull it off, the FNV Brotherhood of Steel actually patrols the long 15 and helps the NCR at Hoover Dam. It’s the only glimpse we get of what they could be if they weren't so stubborn.
Misconceptions About the Mojave Chapter
A lot of people think the Brotherhood in New Vegas is "weak." They aren't. Individually, a Paladin can take down a dozen NCR troopers. The problem is scale. The Brotherhood is a cult; the NCR is a nation.
Another big misconception is that they are the "good guys" because they hate the Legion. They don't hate the Legion for being evil; they hate the Legion for being a threat. If Caesar left them alone, the Brotherhood would happily sit in their hole and watch the world burn. They have no interest in the fate of the Mojave, only the fate of the technology within it.
Survival Tips for the Hidden Valley Bunker
If you're heading in there for the first time, come prepared. The bunker is a maze of identical hallways and sliding doors.
- Bring Veronica. She skips the whole "bomb collar" introduction. It saves a lot of time.
- High Science or Lockpick is mandatory. If you want to finish their quests without running across the entire map six times, you need to be able to crack their terminals.
- Check the lockers. The Brotherhood has an insane amount of high-tier energy weapon ammo (Microfusion cells, etc.) just sitting around. If you’re an energy weapons build, this is your Mecca.
- Don't steal. They have eyes everywhere, and getting vilified by the Brotherhood early game is a death sentence if you aren't leveled up. Those Gauss rifles don't miss.
The FNV Brotherhood of Steel represents the core theme of Fallout: New Vegas: "Begin again, but know when to let go." They are a group that refuses to let go of the past, and as a result, they have no future. Whether you choose to save them or blow them to kingdom come, they serve as a grim reminder that in the wasteland, the ability to change is the only thing that actually keeps you alive.
To maximize your standing with the Brotherhood, focus on completing the "Still in the Dark" questline as early as possible. This unlocks the bunker's safehouse, which contains some of the best free loot in the game, including semi-regular spawns of high-condition T-45d armor. If you plan on siding with the NCR, wait until the quest "For the Republic, Part 2" to initiate the truce; doing it too early can sometimes bug out the dialogue options with Colonel Moore. Always keep a set of non-faction armor in your inventory, because even if you're an Idolized member, the rest of the Mojave will still treat you like a raider if you're dressed as a Knight.
