In what ways do Gen 3 Synths differ from Humans?

The institute has created these (Self-Aware) Synthetic Organisms to be nearly instinguishable to a regular human outside of a synth component. But we know some ways they do differ they don’t age, they don’t gain or lose weight (fat synths need to be specially designed), they are immune to radiation. They aren’t born or even grown in a test tube like a clone but are created on an assembly line. What other ways do Synths differ from human?

Sterility presumably but it seems inconsistent in the lore.

u/EvernightStrangely 5d ago

As far as I know, FEV renders everything it mutates sterile, hence why supermutants can't have children. The Institute uses a modified FEV to create gen 3 synths, even if they found a fix for the sterility side effect, they'd have absolutely no reason to give synths the ability to procreate.

u/ScaryCrowEffigy 5d ago

They’re programmed to do so. The degree to which they can be programmed is debatable since there are mention of subroutines that can be corrected to fix stuttering issues.

I think it depends what the FEV strain was designed for - Deathclaws were FEV derived but can lay viable eggs.

u/vegarig 5d ago

There's a lot of FEV strains around with entirely different effects.

I mean, it was even weaponized twice - Curling-13 and further modified FEV from Raven Rock.

u/Grimskull-42 4d ago

No certain animals can clone themselves by laying eggs with identical DNA to the parent.

They can't cross fertilise and so can never evolve past what they are since you dont get the random mutation from genes mixing.

u/DeadFergus 4d ago

But deathclaws cross fertilize, Gruthar sires the Vault 13 death law eggs himself

u/therealdorkface 4d ago

Nah you can definitely still evolve without sexual reproduction, though it results in less robust populations

2

u/Grimskull-42 4d ago

But they are radiation immune and radiation along with diverse gene bases are the two driving factors for mutation which results in evolution.

4

u/therealdorkface 4d ago

Mutations can happen without radiation.

Their radiation resistance probably comes down to very robust breakage repair, so that mostly leaves transcription errors so far as possible selection mechanisms go. Not robust, not quick adaptation, but probably still technically possible.

In universe though yeah they probably don’t evolve

No, they are 3D printed FEV-infected humans, as per FEV research notes.

Year 2224

This is Doctor Elliott, reporting for the BioScience division. March 2224. We just received another batch of... subjects... but as my previous report stated, we're at an impasse here. More of the same won't help. I am officially echoing the team's position: the most likely progress for our research on synthetic organics requires new avenues of exploration. The two most promising strains of FEV have been adapted to an ideal state, but... we're still missing something. Additional Commonwealth subjects will not help. It's the same problem across the board: exposure to too much radiation. We need something... someone new. There's a proposal we'll be putting forward... I am not entirely comfortable with it, but it seems the best course.

"I am officially echoing the team's position: the most likely progress for our research on synthetic organics requires new avenues of exploration. The two most promising strains of FEV have been adapted to an ideal state, but... we're still missing something. "

Synthetic Organics were attempting to be made using FEV, and failing due to the Wastelander subject's high radiation exposure, therefore the 'proposal' to raid vault 111 was put forward and accepted, leading to Shaun's DNA/tissues being used to perfect the Synthetic Organics project.

Terminal entries within the Institute say otherwise. That's why they even had an FEV lab in the first place.

Is FEV just vibranium for fallout now?

before it made super mutants and when messed up, centaurs, now every single new creature is created with it instead of just being a mutation or some other sciencey thing

Multiple creatures in 76 are FEV based as well. It is sort of generic plot device at this point.

u/Darkshadow1197 4d ago

I forgot about those 2 but thats like 2 creatures out of like the 10-12 in a game that has something completely unrelated. Bio weapons threaten the world and are full of non-FEV mutants. Like the Mega Sloths and Rad Toads aren't FEV, or mole miners, Wendigoes or even the little zap toads.

It's always been a plot device since the first game. Magic goo that makes the Uber men and mind powers, magic goo that'll make the one true humanity inherit the earth and made their monster man. Their synths.

u/Andy_Climactic 4d ago

and bethesda is the main one the does it, none of the new creatures in New Vegas were FNV based, but the Institute has Super Mutants coming back with their own FEV, and Synths, and the second vault which somehow also had FEV in DC, and FO76. I swear they cannot think of a new thing to save their lives

u/BriscoCounty-Sr 2d ago

This is like bitching that Bethesda is terrible cause they rely on things like vaults and radiation for setting up their stories. FEV, nuclear fallout, vaults, wastelands, these are all things that’ve been with us since ‘97 amigo.

“OMG guys can you believe BathesSUCK put power armor in Fallout 5!?!?!?”

u/Andy_Climactic 2d ago

FEV seemed like a pretty specific plot device for the first game’s villain, but okay

it’d be nice to see something new every now and again,

it’s annoying seeing super mutants and BoS in every game even where it doesn’t make any sense, and then they retcon in that every scientist in the country had FEV and messed it up the same way to make super mutants, and every soldier in the US was BoS and in contact with every other one in the country

2

u/vegarig 5d ago

now every single new creature is created with it instead of just being a mutation

Far as I understand, it allows to achieve targeted mutation WAY easier than other methods.

So far, it's been used both in "normal" way (delivery system for mutagenic payloads, allowing creation of mutant lifeforms) and "weapon" way (delivery system for lethal payloads, like Curling-13 strain and modified FEV for infecting waterways).

1

u/Andy_Climactic 4d ago

i guess once i think about it as what it literally is, Forced Evolutionary Virus, it could be pretty versatile if you think of it like a GECK for animals and humans. FEV used on a prewar human makes sense, but it seems like there’s a missing piece to forming new, non clone people with it. Like how you’d still need eggs, etc

u/GameTheoriz 5d ago

Wasn't that for the Gen 2's? The Gen 3 replaces the FEV material with Shaun's DNA.

34

u/EvernightStrangely 5d ago

Gen 2's are wholly mechanical, just with a synthetic skin designed to make them appear human at a glance. Gen 3's are where they get biological. And they needed prewar DNA to to combine with their modified FEV. Shaun quite literally is the genetic template for the Gen 3's. My thoughts is they took Shaun's DNA, used the FEV to shuffle the genetics around so the synths don't end up being clones, and then used this modified DNA to build a synth.

Brahmins aren’t sterile

13

u/Overdue-Karma 5d ago

Brahmins aren't via FEV, unless you use the non-canon Fallout Bible.

2

u/Dizzy-Software265 4d ago

In Fallout (1997) it was heavily implied that at least radscorpions, but logically all major mutations were the result of the vaporized FEV and the background radiation. The reason mutants are sterile in the first place is because the virus detects gametes as sex cells and immediately destroys them whenever they are produced. The only way this cannot be a contradiction is if we were to posit that such indirect exposure mixed with radiation doesn't actually mutate the DNA to become a quadruple helix, but this does seem very iffy.

4

u/Overdue-Karma 4d ago

Well, Radiation alone mutates things. FEV isn't in the atmosphere, that was only mentioned in FO1 and has since been retconned IIRC, or at least it's only in the vicinity of e.g. The Glow and so on.

Brahmin aren't made via FEV, they've been all over the wasteland.

1

u/Grimskull-42 4d ago

Animals born with two heads have a higher resistence to radiation IRl, so when they were born they did better than regular cows in the new world and their genes became dominant.

u/Overdue-Karma 4d ago edited 4d ago

Regardless, Brahmins aren't made via FEV, because FEV isn't in the atmosphere. My original point is just clarifying Brahmins don't have sterility.

u/Dizzy-Software265 4d ago

I mean I understand it was retconned but I wouldn't say that means that it makes Fallout (1997) wrong about itself. In isolation, that was the original lore, and it's fine if the later games contradict that.

u/Overdue-Karma 4d ago

Oh yeah, 100%. I'm just saying that well, Brahmin aren't made via FEV, so hence why they aren't sterile.

Yeah, maybe it was a bit of a stretch for me to say it applies to more animals than radscorpions (within Fallout 1)

u/LordCypher40k 5d ago

Well, according to one of the Institute Scientist, they apparently don't require to eat or sleep or even get sick although one of Curie's comment seem to indicate this is either a lie or they still feel these things but aren't affected by it. Coursers due to their work, are fitted with implants and their organs are tweaked to be more efficient.

On a more humorous note, all synths apparently have an irresistible craving for Fancy Lad Snack Cakes

29

u/MinimumTeacher8996 5d ago

But why is it that gen 3s that replace people sleep? And also how don’t they know? If they don’t eat, sleep etc? Maybe they’re tweaked so that they do need these things? Coursers aren’t

u/BabadookishOnions 5d ago

Just because they may not NEED to sleep, doesn't mean they are incapable of it. The same with eating, drinking, etc. If you're trying to seamlessly replace someone with an identical spy, it would be very obvious that something is off about them if they suddenly aren't eating or sleeping.

16

u/Frojdis 5d ago

He himself will admit that they don't have those features if you use the sarcastic option. It's just a sales pitch.

Curie specifically states she needs to adjust to NEEDING to eat and sleep, not just feeling hungry or tired

7

u/Deadbringer 5d ago

Wanted to look for that voice line, and found an old post digging into it.

He says "You might think so now, but just wait. You've only seen a fraction of what our synths can do. Their potential is limitless." which is not explicitly disproving the alternative line where he talks about their lack of needs as if they are current. But as that thread talks about, the guy is probably conflating now with the potential future.

If the lore is that synths do not need to eat... at all, no nutrients... I would not be too surprised, Bethesda absolutely assassinated any integrity their stories used to have. Like with the kid locked in a fridge for 200 years. I don't agree with it, but there is precedent that Bethesda make terrible lore decisions for the tiniest of reasons.

6

u/Valdemar3E 5d ago

If the lore is that synths do not need to eat... at all, no nutrients... I would not be too surprised

That has been part of the lore since FO3. The FO3 game guide explicitly states synths do not need to eat.

Max Loken stating the same is merely reaffirming that notion.

-2

u/Deadbringer 4d ago

Sure, game guides are never wrong! And totally not written an external consultant who gets things wrong! They are made before the games are finalized, alongside the game development. So they get based on pre-release version of quests and lore. Mechanically, they usually are kept up to date but the lore of Prima guides have many times been outdated compared to the games. So while they can contain extra details not found in the games, they are not necessarily part of the finalized canon (and sometimes in direct conflict, but I did not find a fallout example of that.)

Then they are simply not medically indistinguishable from humans, they are some weird perpetual motion machines. It simply is not internally consistent with the rest of the game.

I would also expect the institute to say "They do not need to eat!!!" and also say you just need to let them use the feeding station once a day to inject nutrient sludge straight into their bellies. Just like they say Synths can't dream and aren't alive, despite incredibly strong and constant proof to the opposite.

But I went to the game guide to check, and find the source since you didn't. Quest walkthrough on page 178, a short bio on Harkness on page 386 and Armitage on 387, which contains the bit

Armitage has the same schedule as Zimmer; he sleeps in the same room and eats the same food-not because he has to, but because he's been programmed to replicate human behavior as closely as possible.

2

u/Valdemar3E 4d ago

Game guides can get gameplay mechanics wrong due to cut content and changed content and whatnot.

But to say that their lore-based statements are false is kind of a stretch - especially when they are reaffirmed in the next installment's actual game.

u/Frojdis 4d ago

u/RedviperWangchen 5d ago

According to Dr. Amari Synth brain is different from 'normal organic brain', and is something between a robot and a human. So Curie's personality can be implanted in synth's brain, which is impossible to human brain.

They can't be too different; In Far Harbor one of the side quests is to find the missing synth. Who had been eaten by cannibal trappers.

u/Weaselburg 5d ago

What you said is pretty much what we know, other then the electronic bits. Bethesda doesn't go too into depth with their internal workings.

6

u/Saramello 4d ago

The game...conflicts itself. There's a scientist committing near unit 731 experiments on them and they can't find a single definite factor outside the synth component in their chest (which you can't get without killing them), besides a possible multiple choice question bias to ONE question (and likely margin of error). The main narrative is there is no difference.

That said, I don't think all the game devs shared notes enough. To list differences mentioned throughout the game in separate contexts (as spoiler free as possible)

  1. Synths don't apparently need sleep.
  2. They cannot discernably age. (Or that might have been a 1-off case, hard to tell)
  3. They cannot gain or lose substantial amounts of weight, as one had to custom-made especially fat due to the human it was replacing.
  4. Each and every one has at least a one "de-activate" code that remains even AFTER full factory reset (as seen in FO3 and 4). In theory if you get the master list you can read through it and see if there's an effect.

u/TheMarkedMen 5d ago

u/DmetriKepi 4d ago

Probably the most significant thing is that they're programmed and conditioned for work based on that programming. And part of that programming seems to be a baseline preference for imposing high defense isolationist agendas in communities, as we've seen with DiMA, Gabriel, McDunnough, Glory, Danse, Harkness, Avery, Chase, and potentially Deacon (if he's a synth). Likewise, you also see a strong tendency towards peak over performance which you see in all of the above as well as Sturgis, Warwick, Magnolia, Nick and pretty much all the Acadians. Both of these traits seem to be hardwired, as they tend to appear even in characters that don't seem to want to engage in them, such as Cog, and in characters that have had memory wipes such as Harkness and Avery. Essentially, they're optimized to live in the institute, and I'm turn they will attempt to recreate institute like living conditions when left to their own devices.

Now given that you see a fairly low cross section of synths it's unclear if these traits are absolute and 100% across the board. It is also unclear what the defect rate is in the programming, but considering that you tend to see it within synths you have close contact with whether or not they've been mindwiped, it's fairly core to their being. It also makes sense that these routines would exist as defaults in institute programming because they simultaneously set them up for making the institute successful, making them successful in the institute, and would be disruptive towards any community they are allowed to participate in on the surface. It also is a failsafe for the institute increasing the likelihood that an institute 2.0 or some sort of spiritual successor would be implemented in the case of the failure or destruction of the original should there be any survivors. It's also worth pointing out that it makes sense to program these functions in at a base level because synths are designed to be closed systems for most of their lifecycle and are designed to evolve and improve over time, so having overlapping, multilayered positive reinforcers to direct them towards desired outcomes helps to ensure the success of the synths within in the context of the institute.

Also synths have a recall code, and can be reprogrammed with greater ease than a regular human.

u/ChromeWeasel 5d ago

The biggest difference not mentioned is that synths can be programmed instantly. With a single command a synth can have its personality wiped out and rewritten. That suggests their brains are not normal in terms of human brain tissue. They are more like super advanced AI portals walking around in a human shell . Sort of like what the bug did in Men in Black.

9

u/Fardesto 5d ago

 That's not how the recall code works at all.   

 Each Synth has an entirely unique code "programmed" into them during their initial creation, and all it does it "factory reset them to a blank slate," for lack of a better explanation.    

 They then have to be physically brought back to the Institute in order to be "reprogrammed."

It's hard to know exactly how they differ, however it has to be subtle enough that a mind wiped synth could go years without realizing that they are a synth. In addition, it can't be anything that can be readily tested, or it would be simple to devise a test to find out if someone was a synth.

There is some misinformation and conflicting information, but synths appear to be biological, based on human DNA, with some implants. The implants can be programmed, but the synth themselves are more complicated, since they have a biological brain.

Synths think and feel the same as any human. They make choices based on their experiences. They can obey or disobey the Institute. Some believe Institute lies, and others want to be free.

I have never heard that Gen 3 synths are immune to radiation, and I don't see how that makes sense.

He is the only synth where that is mentioned, and specifically that he won't be "allowed" to age, not that he can't

Janet Thompson: "He'll be a child forever...''

Because he won't be ALLOWED to grow up. They don't even state that he can't, but that he won't be ALLOWED to, like they continously prevent it

u/Valdemar3E 5d ago

He won't be allowed to grow up because he literally cannot ''grow up''.

She literally says he'll be a child forever. How can it be ''forever'' if they kill him?

The only time it's brought is in regards to Synth Shaun. The scientists say he "won't be allowed" to grow. That could mean

  1. Synths themselves don't age

  2. Shaun is spefically designed to not age.

3.Shaun's aging is actively suppressed and if they stop whatever they are doing, he'll age normally.

No, they are 3D printed FEV-infected humans, as per FEV research notes.

Year 2224

This is Doctor Elliott, reporting for the BioScience division. March 2224. We just received another batch of... subjects... but as my previous report stated, we're at an impasse here. More of the same won't help. I am officially echoing the team's position: the most likely progress for our research on synthetic organics requires new avenues of exploration. The two most promising strains of FEV have been adapted to an ideal state, but... we're still missing something. Additional Commonwealth subjects will not help. It's the same problem across the board: exposure to too much radiation. We need something... someone new. There's a proposal we'll be putting forward... I am not entirely comfortable with it, but it seems the best course.

"I am officially echoing the team's position: the most likely progress for our research on synthetic organics requires new avenues of exploration. The two most promising strains of FEV have been adapted to an ideal state, but... we're still missing something. "

Synthetic Organics were attempting to be made using FEV, and failing due to the Wastelander subject's high radiation exposure, therefore the 'proposal' to raid vault 111 was put forward and accepted, leading to Shaun's DNA/tissues being used to perfect the Synthetic Organics project.

Being made of FEV infected formerly human tissue, synths would gain an immense resistance if not outright immunity to radiation damage, just like super mutants.

u/Thornescape 5d ago

That isn't what it says. It's talking about super mutants. The institute is the source for all super mutants in the commonwealth.

Another batch of wastelanders. More of the same (super mutants) won't help. They are making super mutants in attempts to research synthetic organics. They have modified FEV strains to do so, but the Commonwealth wastelander subjects are too irradiated, and come out as super mutants. An uncomfortable proposal is put forward regarding the organic synthetics project.

Shaun outright states that, "The program was ultimately a success; my DNA was fused with a modified virus to create the organic material from which our new synths are made."

Synths made from organic material = Organic Synthetics.

It is talking about Synths.

u/arceus555 5d ago

I have never heard that Gen 3 synths are immune to radiation, and I don't see how that makes sense

They are made with FEV, which is supposed to make the subject immune to radiation.

u/King-Of-Hyperius 5d ago

They’re all genetically related to Father and thus to Grandfather/Grandmother.

No really, Nate and Nora have no known family besides an unnamed mother on Nora’s side, it’s highly likely that both are single children of single children parents, and even if they weren’t, after 2 centuries of living in a radioactive wasteland and roughly 8 generations of people, any descendants of even genetically identical relatives would have had significantly different genetic makeups that they would effectively be as close genetically as Nate is to the Vault-Tec guy who ended up a Ghoul.

But assuming Dima is wrong about his theory that the Sole Survivor is a synth, then that means Father, who claims to be your kidnapped son Shaun, is a genetic link from the Synths back to you, since the Gen 3 Synths are based off of his dna.

1

u/Tishers 1d ago edited 1d ago

In many ways DIMA is an unreliable narrator; He has stashed away so many different memories that he felt were in contradiction to who he wanted to believe himself to be that the true sum-total of all of his experiences would overwhelm him with contradictions.

The ones that you recover are likely only a subset of everything he has conveniently forgotten. I have played through the Far Harbor DLC several times and each time I come away liking DIMA even less. Getting him in the same room with Nick Valentine you find out that he is condescending. Looking at his set-up of the Children of Atom and the people of Far Harbor sees him in the middle of that tension. He could of been the peacemaker between the two groups but it seems the only solution he can come up with is to murder someone and replace them with a synth who will work to serve Acadia's interests.

DIMA is running a backwoods-redneck, low-budget version of the Institute. He does not even help the synths who went there for sanctuary to set up a functioning society.

I wish there was a mod to make Acadia in to a settlement. Clean up the place, build proper homes, get crops in the ground, assign tasks, maybe make it a technology hub for the island (particularly after the institute is destroyed).

Think what would be possible if Acadia became a school for the children of Far Harbor. That would be an achievement, the learning of technologies, ethics and eliminating ignorance.

2

u/Overdue-Karma 4d ago

DiMa's theory is completely wrong because we do have memories prior to the bombs, and there is no DNA of us being a Synth, on top of that, Father would NEVER put a Synth in charge - he openly tells you he doesn't view Synths as people.

Plus Father would need to trick hundreds of employees which he can't do, he's too stupid.

2

u/Tishers 1d ago

Yea, that was a lopsided discussion about the survivor not having memories of before. You are not given a choice of answering correctly. No thanks to Bethesda wanting to lead us down their rosy path of story continuity.

2

u/Overdue-Karma 1d ago

Yep. Plus Kasumi isn't a Synth and DiMa said she was.

u/Deadbringer 5d ago

The part about losing weight an extrapolation from a note on the Mayor that says it is not worth it to reclaim the unit because he is too fat... But that ignores the rest of the note where it shortly after says this:

Determination: When and if M7-62's identity is eventually compromised, the unit is effectively decommissioned in-field. No reclamation. No Institute assistance. Given its relative age and physical condition (not to mention the danger inherent in an Infiltrator unit's discovery), further lifespan estimated at two weeks maximum.

The mayor is about to fucking DIE! There is NO time for them to even get him fit. They have given him a two week estimate for living! Why would it be worth the effort to put him through a training regime to get fit when he will die in short order?

But I will have to add, this being the institute the "lifespan" they may be referring to is the lifespan of the infiltration rather than the literal body. But I feel the context leans towards them speaking of the body rather than the lifespan of the infiltration mission.

2

u/Overdue-Karma 4d ago

I think they mean two weeks before he's identified as a Synth and murdered, rather than two weeks left to live his life.

2

u/redneckleatherneck 4d ago

Well for one thing, they’re manufactured robots and not actual people, so there’s a difference right there.

-3

u/Overdue-Karma 4d ago

Well...no, they aren't, because Robots are machines, and Synths are organic, not machines. They don't fit the classification of a Robot.

They're more akin to Gary's clones.

3

u/redneckleatherneck 4d ago

They are literally manufactured, and you can see the place in the institute where they are.

They’re fucking robots.

-2

u/Overdue-Karma 4d ago

Cool, still not the definition of a robot. Downvote me all you want, that's objectively false.

They are built synthetically, just like Clones.

Are clones robots?

2

u/redneckleatherneck 4d ago

They are manufactured, with mechanical components, even the gen 3’s.

They’re literally fucking robots. Your clone argument is apples to oranges. At best - absolute best - they’re more akin to cyborgs than clones. But even that’s a stretch.

0

u/Overdue-Karma 4d ago

No, they don't have mechanical components. They have a Synth component put in them AFTER they are created. If I put a component in your head, you don't suddenly stop being a human.

And no, they don't have metal underneath. Stop watching Terminator and learn Fallout lore.

By all definitions of the word Robot, they are not one.

And by extension, people can be non-human. Ghouls, Mutants, in TES, Elves, so on.

1

u/redneckleatherneck 4d ago

Their skeleton is literally mechanical.

Don’t lecture me on fallout lore. Go to the institute and fucking look.

2

u/Overdue-Karma 4d ago edited 4d ago

No...their skeleton isn't mechanical. It is flesh and blood.

That is flesh, blood and muscle.

Nobody is lecturing (except you, and you're being extremely aggressive).

But if you want to prove me wrong, simply show me an image of a Generation 3 Synth with a metal skeleton. Prove to me this claim you made. Show me a Generation 3 Synth that has a fully metal skeleton beneath it.

2

u/redneckleatherneck 4d ago

There’s no point, you’ll just deny it and continue to die on your hill. I have better things to do with my time

2

u/Overdue-Karma 4d ago edited 4d ago

I mean...that's a copout answer. I've provided proof, you have provided nothing but assumptions. I've shown you literal proof right there that there is no mechanical skeleton. I'll deny it if it's obviously a fake picture, yes.

The game explicitly says Synths are indistinguishable from humans. Being part metal would make one instantly know who is a Synth.

If you have better things to do, don't try and attack someone then run away when asked for proof. You made a claim, you refused to back it up, you then got aggressive with me, then you again refused to provide evidence. Just admit you've got none and move on, but don't try and ride the moral high ground.

u/MuddyWaterTeamster 1d ago

It seems like all these differences would be really easy ways for Kasumi or anyone else wondering if they or someone they know is a synth to figure out the truth. Kasumi, just eat pre-war pie and sugar bombs for a week and if you gain weight, you’re golden. No more existential crisis.

u/Chlorophyllmatic 5d ago

I would assume that as designed intelligences they have a greater memory and maybe in some respects (though not all) better processing?

1

u/rom65536 5d ago

Gen 3 synths are NOT immune to radiation. Gen 1s and 2s are, but they are little more than Protectrons.

2

u/Mac-Tyson 5d ago

It literally says on the wiki that coursers are immune to radiation. If that’s not consistent neither is it for non feral ghouls when it comes to radiation damage.

-1

u/rom65536 5d ago

The wiki isn't canon - never has been. It's a collection of what people THINK is canon. But I guarantee you, even a courser will die if you put it in a high-rad environment. So will synth infiltrator settlers. I'd rather trust the game engine for determining canon than the wiki.

u/Valdemar3E 3d ago

Only one way to find out.

1

u/SK-4430 4d ago

They don't age and they have an endoskeleton made of steel instead of bones, their flesh isn't technically organic I think, as far as I remember they are even immune to radiation, and they cannot reproduce.

1

u/Overdue-Karma 4d ago

No? They have fully organic bodies, they don't have a steel endoskeleton.

1

u/Nobody_at_all000 4d ago

I imagine they have various cybernetic systems woven deeply into them, such as a direct neural interface to allow for them to be “programmed”, which might be what the synth component is.

0

u/Overdue-Karma 4d ago edited 4d ago

They're indistinguishable from humans apart from the component in their brains.

Damn, imagine people disagreeing with objective canon fact.

0

u/Nobody_at_all000 4d ago

Oh yeah, I remember hearing that on Covenent’s scientist logs

0

u/Overdue-Karma 4d ago

Not just in Covenant's logs, the entire game itself and the devs say Synths are indistinguishable. This is canon fact, this is why nobody can tell Synths apart.

1

u/Henderson-McHastur 4d ago

Not much. That's the point. Father even emphasizes this in one of the Robotics terminals in an entry called Synth vs. Android. The Institute had lived with Gen 1 and Gen 2 synths for so long they'd grown accustomed to calling them what they were: androids, machines in the shape of men. But Gen 3 synths aren't androids, they're synthetic people: technically machines, in the same sense organic humans are an assemblage of biological machinery, but manufactured bone by bone, sinew by sinew, neuron by neuron.

Father stresses that this is the correct terminology and underlines his own hypocrisy in doing so. The important synths, the only ones really relevant to the moral theme of Fallout 4, are the Gen 3 synths, and Gen 3 synths are synthetic human beings. Their "machinery" is flesh and bone, just like an organic human. The chief difference is apparently the synth component buried in their brain, which serves as an "off button" - when a recall code is used, it's likely the synth component that receives the command and hijacks the synth's nervous system. But this component is invisible, even to the synth, pre-mortem, and doesn't seem to play an important role in their daily function.

What other differences can we identify? Coursers are a special case, but generally aren't manufactured any differently than normal Gen 3s. Their special training and physical enhancements are added after selection from the general synth population, along with an implanted Courser chip that allows them to relay in and out of the Institute. What this does tell us is that synths can receive and process information in a way organics cannot. They can be upgraded, both in hardware and software, in a process that takes a fraction of the years an organic would require.

Synths also tend to demonstrate an aptitude with technology, though this may be a unique attribute of DiMA and Nick Valentine more than a general quality. The other synths of Acadia seem to lack Faraday's aptitude, or else are kept at arm's length from the more sensitive technology in Acadia for infosec reasons. Moreover, Kasumi Nakano is most likely not a synth, given her absence from Institute records, and instead is simply a natural tech wiz.

Critically, synths have a peculiar relationship with death. On the one hand, they don't appear to age, instead appearing as designed until otherwise modified or destroyed. On the other, they can still be damaged by radiation, though if the conversations of Institute scientists are to be taken at face value, they can be designed to better withstand the hazards of the Wasteland. Disease seems to pass them by, and they seem incapable of reproduction if Deacon and his wife are to be taken as normal.

In all, the synthetic aspect of synths appears to primarily manifest in their planned obsolescence. They are designed primarily as tools of the Institute, and so are built to withstand hardship but aren't capable of independent reproduction. They are built, live, and are likely to be sidelined when the Institute moves to another generation of synths. But in all other respects, they are perfect replicas of organic humans, from psychology to biology.

2

u/Valdemar3E 3d ago

Synths operate off of hard- and software, which is given patches and upgrades and use highly advanced self aware AI.

They can be turned offline or terminated outright by merely uttering a phrase, and their brains are different enough from human ones to the point where a robot's conscience can be transplanted into them.

They do not need to eat or sleep in order to function, do not get fat, their personalities come from personality matrixes, and they are infertile.

There are several parts that show that synths are not the same as humans.

u/lars573 5d ago

They were supposed to be physically and mentally superior to normal humans. They were changed to be more or less just humans.

u/Unprocessed_Sugar 5d ago

We literally do not know, and everything we might know is either purposefully or unintentionally contradicted. Nobody responsible for writing the information cared enough to nail out the specifics.

There are massive inconsistencies in what we do know as well. They're obviously made with human cells, given the literal involvement of human DNA, so it's ridiculous to say that they don't require food, drink, or sleep, unless The Institute decided to completely solve human cell senescence in order to manufacture slaves.

Basically, don't ask more questions than the writers did. They really didn't care as much as we do.

0

u/EldritchKinkster 4d ago

They are all genetically related to Shaun. Any faction capable of comparing chromosomes could develop a test similar to a paternity test.

Of course, they'd need to know that they are related in the first place, but if you have the bodies of two Gen 3s, you could discover it while examining them.

-1

u/Artimex723 5d ago

Not really on-topic, but an interesting thought crossed my mind - does the Courier technically become a synth during Old World Blues? I mean, we get those cybernetic implants in the base game already, but in OWB the Courier gets a synthetic brain, heart and spine. Doesn't that make them a synth in a way?

6

u/BB-56_Washington 5d ago

I'd say no. The courier is just like Kellog at that point, they're a cyborg. The Institute never calls Kellog a synth. Even when the couriers brain is out of their body, they're still a natural born human, not synthetic.
