Synth is a common term used to refer to sentient beings manufactured within the the Institute laboratories, ranging from skeletal early models, to those virtually indistinguishable on the outside from human beings.[1]

Nomenclature[]

See also: Synth designation

Both android and synth are technically correct terms, used interchangeably by The Institute to refer to its creation. The former term has been deprecated at Shaun's insistence, following the introduction of third generation models.[2]

Synths are all issued a four character identification number when processed and assigned duties. It always begins with a letter, followed by a number, dash, and two more letters. The precise system governing designations is unknown. X but the M prefix identifies a known infiltrator synth (M7-62)[3] and a synth that infiltrated the structures of the Brotherhood of Steel (M7-97). The only known constant is that X designates a Courser (though there's one with a Z prefix and another with an A).[4]

History[]

Synths have been manufactured by the Institute for decades, with the precise date when the first generation synths were fielded to the Commonwealth remains unknown; however, it was at a time when The Institute had not yet become the bogeyman of the region, and were able to continue their work in relative peace. Further attempts to work peacefully with the native inhabitants of the Commonwealth eventually culminated in mutual mistrust that ended any possible relationship between the two entities quickly.[5]

By the 2170s, the first generation synth were no longer enough for the Institute's needs, and in order to overcome the limitations of limited and non-renewable materials, the Institute endeavored to create synthetic flesh, so that their creations could more safely traverse the above world. Research into this officially began in 2178 under the auspices of Doctor Frederick, on F.E.V. samples, despite the objections of some senior members of the BioScience division.[6] Both women and men were abducted from the Commonwealth and submerged in The Institute's modified FEV, their mutations carefully tracked and extensively investigated. Successful mutations would be monitored to ensure survivability, then tagged and discarded.[7] The research 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.[8]

Just three years later, 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,[9][10] and his DNA became the basis of the third generation of synths in a project led by Dr. Walter.[11] The infant Shaun became Father to a whole family of engineered super-beings. Of course, tests were not without setbacks - in 2229, a defective 3rd generation infiltrator caused the Broken Mask Incident, vilifying the Institute in the eyes of the Commonwealth.[12]

Meanwhile, existing first generation units were provided with a suite of upgrades, in order to increase their functionality and allow for increased deployment into the Boston ruins. Designated as second generation synthetics, bridging the gap between the skeletal and human-like synths, these models are characterized by thick artificial skin, and yellow, glowing eyes that give them the appearance of a creepy porcelain doll. These second generation synths continued to serve the Institute well into 2287, along with the first generation remnants, although plans were made to gradually retire both the first and second generations in favor of organic synths, with the remainder of mechanical units relegated solely to surface duties.[13]

Overview[]

First generation[]

Fo4 1st Gen Synths

A work crew of Gen 1 synths.

The first models created by the Institute are skeletal creatures with an unmistakable provenance. Patterned after the human silhouette, their basic chassis consists of a human-like skeleton constructed from alloys, with the power cell and additional mechanisms stored where the chest cavity would be, while visual receptors and the primary processing unit are contained within the artificial skull. Limbs are minimalist, articulated by a network of tensile fibers, simulating muscle action, like in early human prostheses.[14]

In practice, first generation synths are simple, yet effective machines. They are employed by The Institute for menial labor within the Institute, maintaining the hundreds of systems keeping the underground habitat in operation, and performing tasks that can be easily automated.[15]

However rugged they are, they have major flaws. While capable of recognizing human speech and interpreting commands given to them, they require careful programming and instructing, as well as patches to keep them in operation.[16] The most notorious functionality of first generation synths is navigational software, which requires frequent patching and fixing. Pathfinding software frequently causes first generation synths to try to walk through walls.[17]

Second generation[]

Fo4 2ndGen Synths

A pair of 2nd generation synths in a combat situation.

Main article: Synth (Fallout 4)

The most common variant of mechanical synth in the Commonwealth, second generation synthetics are essentially Gen 1 synths provided with a suite of upgrades to their mechanisms and programming. The most noticeable difference is the inclusion of an internal mesh that shields the mechanisms of the synth from damage and provides support for the artificial skin layer that makes the Gen 2 similar to a human. Their optical sensors are also more advanced models, being essentially mechanical eyes, as opposed to the rudimentary cameras of Gen 1s.[14]

The Gen 2 synths are primarily used on the surface, where the artificial skin layer and improved mechanics improve their performance well above that of Gen 1s. Apparently prototyped using Nick Valentine as basis, Gen 2 synths are primarily used for resourcing operations. They are feared, as they're usually witnessed stripping entire settlements down for parts and killing everything that gets in their way.[18][19] One of the latest targets of a Gen 2 stripping unit was University Point, which saw its population exterminated for resources.[20]

Of course, due to their mechanical nature, mechanical synthetics can suffer from major software bugs, for example, causing them to remain in a single room executing its duties in a loop due to faulty navigation software. Other failures are typically mechanical in nature, with their servo motors and drives breaking down due to age.[17] In fact, most second generation synths have lasted long past their projected lifespans, with all the bugs that crop up due to overuse.[21]

Third generation[]

Main article: Gen-3 synth
Fo4 Courser

A Courser interrogating Gunners.

The most advanced synthetics created by the Institute are fundamentally different from their predecessors. Despite sequential numbering, they are unrelated to their mechanical counterparts, in fact. They are derived from Shaun's pre-War DNA 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 a of synths of varying races and appearances despite the base DNA coming from only one source. They are the result of nearly five decades of research, from 2178 to 2227.[6][9][22][23][24]

Third generation synthetics are unlike humans and some liberated synths do not consider themselves human at all. The reasons for this are multiple, chief among them is the assembly process.[25] Other reasons include the fact that synths do not require sleep at all to function properly, are completely immune to disease, and don't require the intake of food or water to generate energy for their bodies certainly contribute.[26]

Third generation[]

Third generation synths primarily exist as distinct characters, rather than generic creatures for the player to slaughter. There are two generic variants encountered in the Institute: Institute synths and Coursers. Other third gen synths encountered are named:

Appearances[]

Synths appear primarily in Fallout 4. The character Harkness in Fallout 3 is a synth but is referred to as an "android."

Behind the scenes[]

  • The design of generation 1 and 2 synths take inspiration from vintage prosthesis.[27]

  2. The Institute terminals; Robotics Terminal, Synth vs.Android: "As production of our gen-3 synths continues apace, I would like to take this opportunity to formalize our categorization.
    The term android has been used interchangeably with synth for as long as the Institute has existed. And though some of our older residents may actually prefer android (Dr. Zimmer being a prime example), the term synth has always been more widely used.
    Today, our third generation creations are truly synthetic beings, so the designation synth seems more appropriate than ever.
    From here on in, I strongly prefer all official Institute records and correspondences use the term synth or synths. Let us remember our past, and appreciate the legacy of the android. But let us live for the future, and recognize the power of the synth.

  3. The Institute terminals; SRB Terminal, Infiltrator Unit: McDonough: "I'm starting to wonder if M7-62 (the Infiltrator unit "McDonough") hasn't begun to outlive its usefulness. Assuming the identity of Diamond City's mayor has provided us with invaluable intelligence over the years, but suspicions have only continued to mount. This latest incident - the publication of that newspaper article specifically calling McDonough's humanity into question - might just be the tipping point.
    I've spoken with Ayo, and we both agree - if the situation does become untenable, reclamation seems unfeasible. M7-62 was specifically engineered to mimic the actual human McDonough. As such, the unit's synthetic biology is that of someone overweight and grossly out of shape. A mem wipe would kill any psychological weaknesses attributed to self-perceived old age, but that body? Lost cause.
    The real irony here is that M7-62, in one of its dispatches back to the Institute, requested a future posting in the Coursers, citing loyalty and years of surface. And that request alone was evidence of enough self-awareness and independence to completely eliminate him from contention. Never mind the fact that he wouldn't even fit into the uniform.
    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.

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."

    Our first generation synths have served admirably and exceeded their design specifications in virtually every category, but the remarkable breakthroughs in synth design and production that have led to our latest, more aesthetically-pleasing models herald a time for change.
    Over the next several years, we expect to replace all Gen 1 units with Gen 3 units, and in time, we will enact a similar plan with the Gen 2 units as well.

Those early model synths of theirs strip whole towns for parts, killing everything in their way. Then you got the newer models, good as human, that infiltrate cities and pull strings from the shadows. Worst of all, no one knows why they do it, what their plan is, or where they are. Not even me, and I'm a synth myself. A discarded prototype, anyway."

Nothing there but Synths now."
