Warning: Spoilers for Fallout Season 2 Episode 8!
Fallout Season 2 wrapped up today, ending with a few questions answered and a whole lot more questions raised—including a big one (literally) in a post-credits sequence at the very end of Episode 8.
Without getting all the way into spoilers for the episode, Fallout Season 2 ends with some of the characters looking out over New Vegas as a new war begins brewing—a war we'll have to wait for Fallout Season 3 to see.
But wait a minute… wasn't there another war in the works? A different war than the one approaching New Vegas? What's happening with that?
Earlier in the season, Maximus seemingly kicked off a war between the various Brotherhood of Steel factions by bashing Paladin Xander Harkness in the head with a super sledge to stop him from slaughtering a bunch of ghoul children. It was the very thing elder cleric Quintus had warned him about, because if Harkness was killed it would touch off a civil war between the powerful Commonwealth BOS (where Harkness was from) and the weaker west coast BOS factions.
We've heard nothing about that situation since the fourth episode of Fallout Season 2, and it's not revisited in the season finale… unless you sit through the credits.
In the post-credits sequence, we finally get an update. Amid a lot of bloodied and battered members of the Knights of San Fernando chapter of the BOS (Max's old group), scribe Dane delivers a rolled-up parchment to elder cleric Quintus.

"Out of the virtue of my heart, I tried to unify the Brotherhood. And look what it got me," Quintus says as bombs explode and screams can be heard just outside. "Quintus the Unifier is dead. Quintus the Destroyer is born."
He looks down at the blueprints Dane delivered to him, blueprints for what appears to be a large robot labeled "Liberty Prime Alpha." Below that it says "Strategic Army Division | U.S. Army | General Atomics | Robco | Mass Fusion"
What's Liberty Prime?
Like so much from the Fallout series, Liberty Prime pre-dates the Great War. Liberty Prime was a superweapon, a massive robot created by the United States to battle China in occupied Alaska—the war we saw Cooper Howard fighting while wearing power armor in Fallout Season 2. The U.S. built Liberty Prime allegedly because China had created giant combat robots called "Warmachines"—though there was never concrete proof of these robots and this idea may have been created by the U.S. government itself to justify building their own.
Liberty Prime appears in both Fallout 3 and Fallout 4.
"Liberty Prime will be the very embodiment of American military might—a walking, talking, nuke-tossing hero who will remind the world what it means to be a super power," said pre-war general Constantine Chase.
The problem with a giant robot is that it needs a suitable mobile power supply, and the U.S. wasn't able to design one. They could only power some of Prime's different capabilities at the same time—if it had enough power to walk, for instance, it couldn't also fight—so Liberty Prime was never put into service before the Great War.
Liberty Prime after the Great War and the events of Fallout 3
After the bombs fell, the robot sat unused in Washington D.C. until the Brotherhood of Steel found it over 100 years later, though they couldn't get it fully operational (except for its voice module, which constantly delivered anti-communist propaganda at full volume) even after decades of trying. Again, getting all its systems powered up using a mobile power supply proved to be the problem.
Finally, using fusion technology, the Brotherhood got Liberty Prime fully functional and with the help of the Lone Wanderer (the player in Fallout 3) successfully deployed the giant robot against the Enclave at the Jefferson Memorial in Washington D.C. The robot continued to be effective in combat, though eventually the Enclave destroyed it with a missile strike from an orbiting weapons platform.
Liberty Prime in Fallout 4
In Fallout 4, the Brotherhood of Steel rebuilt Liberty Prime, this time in the Commonwealth at the Boston Airport. Called Liberty Prime Mark II, if the player sides with the Brotherhood, the robot gains upgraded weapons like improved eye lasers and the capacity to throw tactical warheads.
The robot was used by the Brotherhood to help destroy the Institute, marching through the streets, saluting war memorials, and still broadcasting anti-China propaganda at full volume. It uses its lasers to bore a hole into the Institute's underground facility, though it is too big to enter it. After defeating the Institute, it can be seen patriotically patrolling the airport.
So, what's Liberty Prime Alpha?
This is about 10 years after Prime stomped its way through Fallout 4, and Elder Quintus has uncovered blueprints for Liberty Prime Alpha, which implies he has instructions for the first prototype of the eventual Liberty Prime robot—or, depending on how you interpret the word "Alpha,' it might be the biggest and baddest Liberty Prime robot ever. The civil war of the Brotherhood of Steel is clearly not going well for the west coast factions, so Quintus wants to build his own Liberty Prime to turn the tide.
I know a lot of Fallout fans were hoping to eventually see Liberty Prime back in action in Season 2, but looks like we'll have to wait. We don't know exactly where this Brotherhood civil war is taking place, but one thing is for sure: Quintus is going to need an advanced power supply if he wants to activate Liberty Prime Alpha. That could mean the war over New Vegas could culminate in the giant robot stomping around on the Vegas Strip in Season 3—if Quintus can take the cold fusion diode back from Mr. House, that is. We'll find out!
What are RobCo, General Atomics, and Mass Fusion?
As seen on the blueprints, these are major pre-war companies in the Fallout universe. RobCo Industries was Robert House's company that designed computers, robots (like protectrons and securitrons), and software, not just for consumers but the U.S. military. General Atomics built industrial robots (like Mister Handy and Mister Gutsy) and weapons like laser rifles. Mass Fusion was an energy company, producing fusion cores and fusion engines. Makes sense that these three companies were all integral in designing a giant combat robot, doesn't it?

Chris started playing PC games in the 1980s, started writing about them in the early 2000s, and (finally) started getting paid to write about them in the late 2000s. Following a few years as a regular freelancer, PC Gamer hired him in 2014, probably so he'd stop emailing them asking for more work. Chris has a love-hate relationship with survival games and an unhealthy fascination with the inner lives of NPCs. He's also a fan of offbeat simulation games, mods, and ignoring storylines in RPGs so he can make up his own.
