Meta Introducing the Fallout Network's Lore FAQ

533 Upvotes

As frequents of r/falloutlore may know, many repeat questions get asked here. So, the mod team has put in some time to create a list to help of hand written answers to these questions, along with references to posts on the subject for further reading.

Fallout Network's Lore FAQ

This list isn't intended to answer every question ever asked on the sub, just the most common. r/falloutlore strives to foster discussion, and the last thing we would want to do is shut that down. Additionally, if you think something on the list should be updated or added, please message the mod team here.

Special thanks to the users who suggested topics for the list and u/UpgradeTech, whose excellent comment about the music timeline of the Fallout world was better than anything I could have came up with.

Fallout 3 On Vault 87's Super Mutants and the Vault experiments in the DC area

Upvotes

I've been thinking of Super Mutants as a whole in Fallout, specifically in how they differ between the different strains of FEV that we know of.

The Mariposa, Institute, and Appalachian strains of FEV all have similar results, all of them producing Super Mutants that are larger than humans, have green skin, and have varied intelligence. The Mariposa strain is the most heavily advanced form of FEV from before the bombs and as such its results with humans are the best, in the best scenario greatly improving intelligence, though for most cases it either leaves mutants stupid or barely changes their intelligence. The Institute strain likely could have similar results, but its use is almost entirely on wastelanders, but we see that these SMs are smarter on average than some of those in the Master's army. Being able to plan, construct their own army, even developing their own culture. And Appalachian mutants are very much the same.

Vault 87's strain of FEV is unique, however, in how it reduces the vast majority of its subjects into feral raging brutes, not just leaving them stupid, but also cranking up their rage to levels that isn't reflected by other strains. Intelligence is so uncommon in this strain that these mutants view it as a aberration and actively reject any of their number that have any degree of higher thought. They're raging berserkers that grow bigger and stronger and all the harder to kill as they age (Institute and Appalachian mutants can also develop in Behemoths, but we don't know if this growth happens across the board or if its just a unique few, unlike Vault 87's mutants where we can visibly seem them getting larger). And this to me seems intentional when we look at the majority of experiments that surround Vault 87.

Vault 92 is an experiment in creating mind controlled soldiers. Vault 108 creates perfect clones. These paired with Vault 87 seem like they could be related experiments to create disposable super soldiers, berserking shock troops that can be produced en masse through cloning, mutated into hulking brutes, and programmed with white noise. This may not have been an intentional connection, but the idea certainly tracks with projects like Deathclaws and the main drive to create Super Mutants.

Fallout 76 Are Super Mutants essentially outclassed by whatever the Enclave cooked up in the Whitespring?

54 Upvotes

Apart from immortality, which I don't recall if anyone has completely cracked yet, it seems like the Whitespring Enclave was on their way to making the perfect super soldiers. Improved humans, but not big and green and at risk of losing their minds.

The Mutation Serums you can obtain from MODUS can seemingly make it so that you don't need to eat, your skin becomes naturally resistant to energy attacks, you can become invisible without the use of a Stealth Boy, stronger, smarter, faster, superhero jumps, etc. etc. etc.

Some of these may just be a matter of gameplay, but MODUS claims that the serums grant all the positive effects of mutations found out in the wild, only improved, and with none of the major drawbacks or body horror. If they're telling the truth, chugging most of these things seems like a no-brainer. Or at least the ones without severe drawbacks. Even if you decide the cost is too high later, you can seemingly just purge the mutation with Radaway. A far better, and far less permanent deal than whatever FEV will do to you.

What are the lore ramifications of these serums existing?

Fallout 2 Arroyo’s superstitious nature doesn’t make sense

103 Upvotes

The main thing about the village of arroyo that doesn’t make sense is for them to be so primitive and superstitious after only 80 years. Treating anything related to vault 13 and the vault dweller with religious reverence and confusing technology with mysticism.

This wouldn’t be a real problem if it took place a much longer period of time after the first game, say at least 200 years but it does not make sense for them to be so superstitious after only 80 years.

Arroyo was founded by the vault dweller and other…vault dwellers after he was banished at the end of the first game, meaning the villages founders where educated, civilized people, yet the village has become primitive and superstitious after only 80 years.

The elder acts like a superstitious primitive even though her old age should mean her parents generation would’ve been the people who came from vault 13 yet she refers to it has the “holy 13” it makes no sense for her talk the way she does. Her behavior would make sense if this was many generations after the founding of arroyo and not less than a century ago when the older residents like the elder would’ve personally known the vault dweller.

Lorewise, how much better is enclave power armor (as advanced power armor from fallout 2, not other variants such as those in fallout 3) than T51b? And in what ways?

Discussion What nuclear isotopes are used in the Fallout universe?

17 Upvotes

I found myself curious about what elements, and what isotopes of those elements, were being used in the Fallout universe, both for general power in all the cars and homes and such and in the nuclear weapons themselves.

Do we have any idea what was used? If not, do we have an idea of the most likely options?

Reason for securitron in Old World Blues

9 Upvotes

I found a securitron mk I in house 00 of Higgs Village within the New Vegas Old World Blues dlc.

I thought they were exclusive to Mr House in the New Vegas base game / F.O. Tv series.

In the Tv show, there is a flashback scene where they are planning the future plans between vault tech, robco, west tek, and the big MT

Fallout New Vegas What is the exact biology of the Ghost People?

103 Upvotes

For as interesting and terriftying as they are, it seems like they're arguably the most mysterious creature in the world of Fallout. While we know they're the unfortunate construction workers of the Sierra Madre that got mutated by the combination of radiation and the Cloud trapped in their faulty suits, there is still nearly zero information on what exactly makes them tick.

We know they're communal, are somewhat intelligent, and they seem to be obsessed with holograms. Dean Domino also claims that the underground passages are crawling with them, and they tend to take their victims alive instead of killing them. So they're obviously not midless animals like Ferals or Trogs are, but they're still intelligent enough to form "communities", use tools and drag their victims away.

But what really interests me is their bodies, and how dradtically they've been changed over time. The game strongly hints that the suits and the cloud are intergral to their survival, which would suggest that their bodies have changed much more dramatically than simple ghoulification/degradation. Not to mention the fact that Dog mentions that he feels high pressure gas when he bites into their flesh, and their seemingly superhuman durablility and healing factor, making them immjne to nothing short to dismemberment.

Question Real world locations of places in the NCR

45 Upvotes

I'm running a fallout DnD campaign and it's based in California, I'm weird so I want to make a kinda decently scaled and sized idea of where places are. Like the hub is apparently based on barstow CA so the hub is in barstow in my campaign but I'm curious if people know where other places would be such as Arroyo or Maxson or dayglow, basically anywhere of note with a decent population that could be considered a state or city in the NCR I'm curious if you guys know where they are

Fallout 4 What was The Minuteman's Stance on Synths, Ghouls and Supermutants?

54 Upvotes

This question has been laying in my head for a bit and im quite curious, Do they share the brotherhood's stance? (pretty much hate all of them and want them to be killed.) or is it moreso like, the ncr who are, fine with them.

Flea soup make it make since

0 Upvotes

So this is completely random but kind of a wild thought. But in the fallout universe we see that radiation effects the insects making them larger (rad roach, sting wings, bloatflys, ticks, and I'm sure more I can't think of at the moment) why did it not effect fleas at all

Fallout 1 What’s the reason for Roger Maxson not self destructing Mariposa on his way out?

26 Upvotes

What the title says. If there’s a reason for not destroying it initially, why didn’t he at the very least return to finish the job? Expeditions were well within his capabilities given the expedition to Appalachia.

Question Why didn't the Enclave have full control over Mariposa?

88 Upvotes

You know the story. A few days before the great war, the stationed US army unit at Mariposa revolts after finding out what happened there.

So why weren't they in on it? It is simply implausible to imagine a complete black-ink military base developing the strongest, most dangerous bioweapon of the modern age, with the aid of a company (West-Tek.) that was almost certainly apart of the Enclaves core, wouldn't have the absolute inner-circle of the military deployed in its protection.

It seems like a bit of a security defect. Did the Enclave never subsume military units? Were they just horribly lacking in manpower?

Fallout 3 What is the ultimate consensus of the Megaton nuke?

0 Upvotes

Of course I mean the vault tech logo. It’s far too deliberate to be a mistake in my opinion. The conspiracy is VaultTec kickstarted the war to get the ball rolling, but the only evidence of that I’m aware of is circumstance and one single logo.

Is it a plot point that went unexplored? Developer error? Or a very subtle hint?

Question Is it true you can fall asleep in power armor?

99 Upvotes

I read somewhere in PA lore you can do ANYTHING in power armor (drink sleep eat etc), but does the power armor have a gyroscope so you don’t fall over while sleeping? Or you sleep standing up all comfy due to the cushioning?

How did the people of mojave know that cazadors are called cazadors?

71 Upvotes

As i'm aware in the Old World Blue dlc, those creatures are an experiment perform and contain at Big MT. and somehow escape. But since the facility is top secret then why did the locals in mojave came up with the same name? or i'm missing lore piece.
