Third generation synths, or gen 3 synths, are the apex of the Institute's research into creating a race of servants necessary to maintain their subterranean habitat.
The most advanced synthetics created by the Institute are fundamentally different from their predecessors, the result of nearly five decades of research, from 2178 to 2227. The research used a sample of the Forced Evolutionary Virus and was intended to produce effective synthetic organics, but it ground to a halt in March 2224, as the research team concluded that the organic synth project could not proceed despite perfecting two FEV strains for the project. Radiation-induced hereditary damage proved too much of an obstacle.[1]
Before developing the first truly organic synths, the Institute prototyped the next generation as mechanical synths like generations 1 and 2. Two prototypes were developed distinctly from each other, one testing independent development through experience and one based on a pre-existing personality derived from pre-War brain scans. Each developed their personalities with promising results but both escaped sometime before the Institute could continue experimenting. In 2229, a 3rd generation prototype designed to mimic a human man was field tested in Diamond City and malfunctioned, causing the Broken Mask incident and vilifying the Institute in the eyes of the Commonwealth.[2]
In 2227, the organic synth project was spun off from the FEV research initiative due to the acquisition of Shaun and his undamaged pre-War genetic code. He was recovered by Conrad Kellogg,[3][4] and his DNA became the basis of the third generation of synths in a project led by Dr. Walter.[5] The infant Shaun became Father to a whole family of engineered synthetic beings.
Biology[]
Despite sequential numbering, third generation synths are unrelated to their mechanical counterparts, but are derived from Shaun's pre-War DNA and extensively modified using the Institute's own research into the Forced Evolutionary Virus, combining the advantageous adaptations encoded into FEV with the versatility of the human body shape. This allowed the Institute to create a variety of synths of varying races and appearances despite the base DNA coming from only one source.[3][6][7][8]
Organic synths are assembled inside Institute Robotics from scratch: The skeleton is assembled by giant machines and serves as basis for artificial soft tissues woven on top of it, including analogues for all human components: Brain, lungs, digestive tract, muscles and so on. The unfinished synth's organs are then kickstarted using powerful electric charges and placed in a fluid bath that completes the activation process by rapidly covering the synth in artificial skin. The synth then emerges with the mental faculties of a full-grown adult human. The blank synth is then ushered for processing: Programming and job assignment.[9] Though entirely biological, each Gen 3 synth contains a neurological implant inside their brain allowing them to be "programmed" and manipulated via voice commands. This implant cannot be detected or removed without killing the synth.
Synth components and programming seem to be unreliable at best in Gen 3s, with some Institute synths requiring repeated wipes, and others escaping when sent to work on the surface. Mind wipes in particular have a high failure rate that results in moderate to severe brain damage. Even the Institute's recall codes are unreliable, with Justin Ayo admitting that too often, returned synths are "unsalvageable".[10] The Institute also avoids relying on programming for surface agents: instead of building coursers, they observe third generation synths for specific traits, then train and upgrade them.[11] When they decide to replace a wastelander, they do not take the original's memories and implant them in the synth. Instead, they either send the replacement to directly kill and replace their target,[12] or if they are replacing a person of importance, they may capture them and torture them for information to help the replacement blend in.[13] This not only takes longer, but relies on getting an honest and self-aware self-assessment from the wastelander. This explains why Institute infiltrators are usually uncovered because their personality and behavior are seen to have changed significantly overnight.
Third gens are human-like, but some liberated synths do not consider themselves human at all. The reasons for this are multiple, chief among them being the assembly process.[14] Third gens are physically incapable of gaining weight past a predetermined limit.[15]Max Loken, a scientist in Robotics, claims that synths do not require sleep at all to function properly, are completely immune to disease, and do not require the intake of food to function.[16] However, synths evidently still feel sensations of hunger and sleepiness,[17] and Alan Binet also claims that his synth Eve has been dreaming while she sleeps, observing involuntary twitching and rapid eye movements during sleep.[18] Synths can also still eat and digest food and even appreciate taste. All third generation synths share an affinity for Fancy Lads Snack Cakes, mystifying Institute scientists.[15] Synths may also merely be more infection-resistant rather than fully immune, evidenced by the upgrade notes for a new model of synth blood.[19] According to a conversation between Janet and Enrico Thompson, the child synth Shaun will not age, which means that possibly no synth does.[20]
Upgrades[]
Third generation synths undergo frequent upgrades and patches in a manner similar to robots, and upgrades are constantly in development. Additional implants apart from synth components are often used on Coursers, such as neuro-servos and other implants which were common around the 2240s.[21][22] According to cut terminal entries, the most experimental upgrades concern their synthetic brains, through the enhancement of specific areas.[23] For example, 2287 saw a major upgrade to synthetic optic nerve tissue for over thirty synthetics, increasing visual acuity by 10 to 12 percent.[24] Other upgrades the Institute implements in its synths are:
Software package updates, which can provide incremental increases in eg. firing accuracy.[19] The software used by third generation synths may become bugged and require patching.[25]
Transfusions, which swap out the entire synthetic blood used in organic synths for superior types that provide improved clotting and infection resistance. Artificial blood strains are identified with codes and the latest upgrade in 2281 switched from blood 77-01 to 90-10.[19]
The latest models of the third generation display increased autonomous behavior, resulting in a greater number of escapes. Alan Binet, head of Robotics and their chief designer, came under suspicion, leading the SRB to order a full examination of the behavioral mapping in these models, looking for signs of interference.[26]
Identification[]
Generation 3 synths are physically and mentally indistinguishable from ordinary humans, having lab-grown bodies of real human flesh, bones, and organs instead of plastic and metal. Even their DNA is close enough to human to seem ordinary. For example, the Brotherhood of Steel keeps their members' DNA on file, and only discovered one member was a synth once they had Institute records of synth DNA to check against.[27]Dr. Roslyn Chambers, a scientist researching a foolproof way to detect synths, found that no medical tests or procedures can identify someone as a synth without killing them.[28] Psychological tests, such as Covenant's SAFE test, show some promise but are dubious at best.[29]
Rumors abound in the wasteland about traits or behaviors that identify a synth, but even mind-wiped synths such as Captain Avery or Gabriel are unable to tell what they are and firmly believe they are human until it is proven to them.[30][31][32]
Discrimination[]
Although gen 3 synths would qualify as sentient beings by the standards of most of the wasteland, they are generally perceived as agents of the Institute and treated as hostiles if discovered.
In the Institute, most are keen on keeping synths under their direct control as servants. The Institute says repeatedly that synths are essential to its continued existence and will redefine humanity, but do not seem to have any intention of allowing them free will or status as full members of the Institute. The disastrous actions of some synths "liberated" by the Railroad, such as Gabriel, are cited as evidence that synths cannot be trusted to make their own decisions.
Few challenge the ideology and those that do are considered radicals. Robotics head Alan Binet is a noted radical, with his impassioned speeches about artificial sentience and machines a constant feature of Robotics. Binet is keenly aware that his words fall on deaf ears, and when reminded of the option to trade the Institute for the wasteland, is quick to remark that he is only trying to broaden the horizons of his colleagues.[18] His ideas are unpopular, especially when he suggests that synths could be the redefinition of humanity. The situation is made worse in the light of the recent increase in autonomous behavior among the latest gen-three models.[26]
↑ 3.03.1The Sole Survivor: "Human synths? Really?" Shaun: "Human-like synths. A great distinction.""The Institute endeavored to create synthetic organics. The most logical starting point, of course, was human DNA. Plenty of that was available, of course, but it had all become corrupted. In this... wasteland... radiation affected everyone.""Even in their attempts to shield themselves from the world above, members of the Institute had been exposed. Another source was necessary.""But then the Institute found me, after discovering records from Vault 111. An infant, frozen in time, protected from the radiation-induced mutations that had crept into every other human cell in the Commonwealth.""I was exactly what they needed. And so it was my DNA that became the basis of the synthetic organics used to create every human-like synth you see today.""I am their Father. Through Science, we are family. The synths, me... and you." (Shaun's dialogue)
↑Synth manufacture process inside Institute Robotics.
↑The Sole Survivor: "I'd like to know more about the synth reclamation process." Justin Ayo: "Fine. Once a Courser has located a rogue synth, it uses that synth's recall code to wipe its memories and render it inert. We then begin the delicate process of restoring the neural pathways to their original configuration. In those cases where the procedure is successful, the synth returns to duty with no memory of its time on the surface. All too often, we're unable to repair the damage and are forced to dispose of the unit entirely." (Justin Ayo's dialogue)
↑The Sole Survivor: "You mentioned that Coursers undergo special training. Tell me more about it." Justin Ayo: "The SRB constantly monitors our gen-3 synth population, looking for specific traits. Those who show tenacity, fearlessness and independence undergo a rigorous training regimen. We teach them armed and unarmed combat, investigative techniques, psychology and mechanical skills. Those who pass a final evaluation become Coursers. The rest have their memories wiped and return to their former duties." (Justin Ayo's dialogue)
↑The Sole Survivor: "Why don't you just tell me how this happened?" Art: "How this... fine. I was on my way to Bunker Hill. I round a bend and I see this guy. Me. Gun drawn. Ready to fire. After that, it's, it's a blur.We scuffled for a while but I won. Now I don't know what else I can say to convince you. He's the synth. Now are you going to get out of my way?" (Art's dialogue)
↑The Sole Survivor: "How do they make synths?" Glory: "Damned if I know. The machines are... massive. Complicated. Not like anything I've seen out here.No matter what Dez and others say, synths ain't human. We're assembled bone by bone. Muscle by muscle. I've seen it.I'm gonna hit the range. I need to shoot something. Now." (Glory's dialogue)
↑The Sole Survivor: "What makes them superior?" Max Loken: "The list of improvements is exhaustive. I can talk for an hour and still not cover all of it. Imagine what you could accomplish if you could live without fear of hunger or disease. Imagine what you could create if you could use every waking moment of your life as you saw fit, with no need of sleep? Like I said, a momentous time." (Max Loken's dialogue)
↑Curie: "All of these bodily functions. How do you keep track of them all? I am hungry, I am sleepy. The list goes on." (Curie's dialogue)
↑ 18.018.1Max Loken: "Come now, Alan. It could have been anything. It was probably just a glitch in the nervous system. The fine motor control software could use an update." Alan Binet: "If it were just a limb twitching, perhaps, but her eyes were moving as well. Involuntary twitching and rapid eye movements while sleeping can only mean one thing, Max.You just don't want to admit to yourself what it is." Max Loken: "If you're about to launch into one of your impassioned speeches about artificial sentience and machines with souls, don't bother. I've heard enough of them by now. Hell, I could write them down from memory." Alan Binet: "But we can't just ignore the question. If a synth can dream, why can't it have a soul? And if a synth has a soul, then it is a living person by every standard we can measure.Of course, it's far more comfortable to think of them as machines, so we can do what we want with them." Max Loken: "If you disapprove of the work we do here, Doctor Binet, you know where to find the teleporter." Alan Binet: "Now just a moment, I never said that. I'm simply trying to open everyone's eyes to new possibilities." Max Loken: "Well it's an unwanted distraction. We're men of science, not philosophers. You'd do well to remember that." (Alan Binet and Max Loken's dialogue)
↑Enrico Thompson: "What's wrong? You look upset" Janet Thompson: "Nothing... I saw the synth Shaun today. There's something about him that just makes me sad." Enrico Thompson: "Why? He's not perfect, but he's a remarkable step forward for the program. You all did an amazing job." Janet Thompson: "No I know, but I can't stop thinking about him. He's supposed to be an exact replica of a child but that's all he'll ever be. It feels wrong." Enrico Thompson: " I don't understand what the issue is. He is as real as any child I've ever seen." Janet Thompson: "That! We gave him every capability of a real child, except a future. He'll never age, he'll never be allowed to grow up or have a family of his own." Enrico Thompson: "So you're worried about what will happen to him?" Janet Thompson: "He'll be a child forever...Sometimes I feel we have no right to do the things we do, just because we can is not a reason. I think we made a mistake." Enrico Thompson: "Janet, don't say things like that. Someone might not understand, and take it the wrong way." (Enrico Thompson and Janet Thompson's dialogue)
↑The Lone Wanderer: "The android is dead. See, here's an internal component. <Lie.>" Zimmer: "What? Let me see that! This is a Neuro-Servo... Unique to the A3-21... I... And you say you got this from his corpse? I suppose there's no other way you could have obtained it. Well... damn it. I was afraid this would happen, out here in this, this... Wasteland. Well. Here's 50 caps for your troubles. Try to buy yourself an education out here in this hell. Good day." (Zimmer's dialogue)
↑Harkness was made in 2242 and likely received his implants during creation or slightly later.
↑ 26.026.1Institute scientist: "In light of recent events, we've been asked to take a look at the behavioral mapping in the gen-3s." Alan Binet: "I see...Another of Doctor Ayo's manipulative power plays. Well he's wrong. The Gen-threes are functioning just as designed." Institute scientist: "SRB doesn't agree. Statistically, the gen-threes have shown an increase in autonomic behavior, suggesting a malfunction in the latest models." Alan Binet: "I assure you Doctor, that is not a malfunction." (Institute scientist and Alan Binet's dialogue)
↑The Sole Survivor: "That's impossible!" Elder Maxson: "I'm afraid not. The evidence is quite damning. The data you brought back included a record of each subject's DNA. We keep the same information on file for all of our soldiers.Paladin Danse's DNA is a perfect match for a synth they called 'M7-97'.To make matters worse, he's gone AWOL. Disappeared without a trace.His sudden absence simply reinforces our conclusion that "M7-97" and Paladin Danse are one in the same.I'm finding it difficult to believe that he never confided in you and then swore you to secrecy." (Elder Maxson's dialogue)
↑The Sole Survivor: "You can't seriously want to kill all the synths..." Doctor Roslyn Chambers: "We most certainly do. But we have to find them first.A living synth is indistinguishable from a human by any medical test yet devised.But, it turns out, psychology can detect a difference. Enter the SAFE test.The test is in its infancy, but through sacrifice and perseverance our success rate is improving." (Dr. Roslyn Chambers' dialogue)
↑The Sole Survivor: "And the SAFE test works?" Doctor Roslyn Chambers: "Oh, yes. Autopsies confirm the test is getting more accurate.There's something in the questions which provokes a response from synths. But the exact trigger is elusive.The margin of error is admittedly high, four or five false positives per synth. But one day we hope to get it to one or two false positives." (Dr. Roslyn Chambers' dialogue)
↑The Sole Survivor: "I have proof that DiMA killed the original Captain Avery. Here." Captain Avery: "I... But that's... My locket. It was lost in a fire.And... the skull. It can't be...Listen, I'm me. I remember everything.I can't be... a synth. You're wrong." (Captain Avery's dialogue)
↑The Sole Survivor: "If you're lying to me, this is your one chance to come clean. Understood?" Captain Avery: "I am... Well, I feel like I am Captain Avery.If I'm a synth they made me believe I'm her. I don't know why." (Captain Avery's dialogue)
↑The Sole Survivor: "Gabriel, you aren't who you think you are. You're a synth, and we're here to take you home." Gabriel: "A synth?! What the hell are you talking about?I remember my whole life. I know where I grew up, and who my parents were.Explain that to me!" (Gabriel's dialogue)
