Synths or synthetics, is a term used for biomechanical organisms used by the Combine, from reconnaissance to heavy combat.[1][2] Their presence underscores the Combine's technological dominance and the oppressive regime established on Earth.
Overview
Synths are biomechanical beings, cloned and synthetically recreated by the Combine.[1] These modified organisms, cloned from existing species, are equipped with advanced weaponry and possess remarkable durability.[2] Their exact origins and the extent of their biological components remain unclear, however, the Strider was observed to possess a brain in Episode 2.
Synths vary in shape and size depending on their function, but are recognizable by what appears to be a fusion of mechanical and organic parts. They commonly appear to have organic structures such as compound eyes, segmented legs, and organic-looking skin. These features are heavily contrasted by the mechanical components implanted into their bodies, such as weapons, propellers, or propulsion engines.
The name 'Synth' itself is used as a short for "Synthetic", in reference to their nature as synthetic organisms.
Synths are highly resilient to damage, their tough carapace armor easily shrugging off small arms fire. Exceptions include the vulnerable Shield Scanner and the more durable Hunter. While their outer shells are impenetrable by conventional weapons, they can be breached by the repeated use of explosive weapons, such as RPGs and grenade launchers. Their advanced weapons and their extraordinary durability make Synths invaluable assets for the Combine's military forces, enabling them to dominate battlefields with overwhelming force.
The Magnusson Devices were proven to be the most efficient weapon against Striders, causing them to quickly self destruct, they served as a critical component to the resistance's victory in Episode 2 .
The Citadel houses extensive factory facilities where Synths are manufactured and augmented. For instance, Stalkers can be seen working on Gunships in the lower levels.[3] From its highest levels to its deepest depths, various types of Synths are observed moving about in an orderly fashion.
Synths are never observed to be "self-replicating" in-game, but are observed to be manufactured by the Combine.
Striders can be seen in a newspaper photo as part of an article detailing Earth's surrender, indicating that either they have been a core unit of the Combine invasion, or were deployed after the war was over.[4]
Known Synths
Various types of Synths have been brought over to Earth by the Combine after their victory over Earth's forces. Some, such as the Shield Scanner, are merely used as scouting or transport and have little to no weaponry. Others, such as the Strider and Gunship, are infamous among the remaining human Resistance as fierce war machines. However, some Synths have remained unknown since they have not been encountered yet or are only deployed on certain situations.
Currently, the Synths that have been shown on Earth are:
- Advisor Pod: seen for the first time by Gordon Freeman and Alyx Vance. Known amongst the Vortigaunts and possibly some Resistance members.
- Combine Dropship: regularly encountered and well-known by the Resistance.
- Combine Gunship: regularly encountered and well-known by the Resistance.
- Hunter: well-known amongst the resistance forces in the Outlands. Hinted to be unknown amongst rebels based in City 17.
- Shield Scanner: encountered in City 17. Presumably well-known by the Resistance.
- Strider: regularly encountered and well-known by the Resistance.
- Crab Synth: seen only by Gordon Freeman within the Citadel, possibly deployed against the resistance in unknown locations.
- Mortar Synth: seen only by Gordon Freeman within the Citadel, possibly deployed against the resistance in unknown locations.
Logos
Most Synths bear at least one logo. Gunships and Striders bear the same logo on their back and head, respectively. This logo was on the back of the Overwatch Soldier's old texture (in white) and can also be seen on the shoulder of one of the Combine Synth Elite Soldier versions. Its meaning and relation to the Combine are unknown, as are the possibilities of it proving any relations between the Strider and Gunship. Other Synths such as the Shield Scanner, the Dropship and the Advisor Pod bear the standard Combine Logo, while the Shield Scanner also bears a trimmed "CMB" logo (like the City Scanner). The Mortar Synth, Crab Synth, and Hunter bear no logo at all. One theory proposes that these logo variations hint at the Synths' factory origins. The unusual insignia could signify an extraterrestrial origin, while the Earth-derived "CMB" logos might point to Synths invented locally, specifically for the conditions found on Earth.
As for the cut Synths, the Wasteland Scanner bears the standard "claw" logo (in dark Red), and other unknown markings, partially seen in the Overwatch Soldier outfit. The Combine Guard has no logo, while its predecessor, the Combine Synth Elite Soldier, has some informal logos in some of its versions, as well as the Gunships / Strider logo, as stated above. The Sacktick has two informal logos, one on its back, one on its right front leg, not seen elsewhere. The Combine Super Soldier has the number "314" in its concept art (also featured in the Beta Overwatch Soldier outfit), and two Red triangles in a Red-rounded circle, reused for the Overwatch Soldier outfit, although with different colors. It also has Red strips in several locations.
Behind the scenes
- According to Dhabih Eng, the team tried to incorporate elements that were neither strictly organic nor purely mechanical to suggest their original organic forms. They did not want to have giant alien creatures with armor attached or implants added, but rather show a forceful evolution of the equipment unnaturally imposed on them by the Combine. In the end, the designs intentionally blurred the line between machine and animal, in their appearance and more importantly their motion and how they reacted to the world around them.[5]
- According to the book Raising the Bar, Ted Backman's idea was to start Synths as androids or synthetic creatures that have been enslaved by the Combine through conquests and wars. Mentioned as "Self replicating robots that evolve", instead of having to be maintaneed, repaired or upgraded, they would make a new version of themselves every five years. Ted Backman says Synths were inspired by the android Bishop, featured in Aliens.[5]
- In an interview for The Final Hours of Half-Life: Alyx, Tristan Reidford recalled asking Backman whether Striders were existing creatures subjected to cybernetic modification by the Combine, to which he replied that the Combine scanned the creature that would become the basis of the Strider's design in its natural habitat before recreating it synthetically.[2]
Cut Synths
Several Synths were cut from the final game:
- Combine Guard (part-human, part-Synth)
- Combine Super Soldier
- Combine Synth Elite Soldier (part-human, part-Synth)
- Sacktick
- Assault Synth
- Combine Mobile Mine
- Attack Synth
- Wasteland Scanner
Early Synths
Several pre-release materials gives some insight about the early Synths.
"Weather Control Vignette"
Raising the Bar features a story fragment of the Weather Control chapter given to the developers for design inspiration, relating parts of the Weather Control battle, with early names for the Combine units. For example "mech" seems to stand for the predecessors of the Synth, while "mech carrier" likely refers to the Combine Dropship. The text depicts the mech looking like Dog's cousins, but apparently new-minted and flawless, and with a "head" in quotes, suggesting that it is strangely-looking. Also, at some point in the text, its head pulses with a faint glow as if powering up for energy, then fires, which is very similar to the Strider's warp cannon, added to the fact that it is brought by a "carrier", the Strider being brought by Combine Dropships without their containers. Added to the gun located in its head, it also has mounted guns.[5] This "mech" could be an early version of one the Synth predecessors of the Overwatch Elite, the Combine Synth Elite Soldier, which has been through several iterations with strangely-looking heads and a narrow waist like Dog (as in the picture seen here), or the Combine Super Soldier, also with a strangely-looking head.
"TBot1"
A folder called "TBot1" can be found in the model textures files from the playable Half-Life 2 Beta files, in a folder called "obsolete". These are likely the textures for the early "mech" or (ro)bot from the Weather Control story fragment, a very early NPC, since they possess some similarities with Dog in design, mirroring the Weather Control story fragment covered above. Since Dog is said to be one of the few concepts that went from the first sketch straight into the game with relatively few changes to the design,[5] it could be assumed that the Weather Control mechs are two-legged and bear similar colors and body part plates to Dog, since he was made from scraps from different metal sources, such as Combine metal (an old texture file for Dog also shows a "15" like logo also found in the TBot textures).
The textures also suggest a slightly battered robot and show round eyes that recall the City Scanner's eye (Dog's head). They also show that a yellow color scheme was to be used, and suggest that a bipedal, paw-footed design like Dog's was also to be used. The model is however missing, and it is next to impossible to guess its shape from its texture files. The "1" in the folder's name also suggests that there were probably other versions, (such as non-battered conditions or other colors). Other texture files suggest that TBot had an antenna and was equipped with a flamethrower, and that some of its internal circuits were to be visible and blue, like the early Combine Dropship, the Crab Synth and the Mortar Synth. The files also suggest a "collar" made of green fabric, with the same fabric on one shoulder and the thighs, showing another example of the old concept of the Combine recycling human materials.
The TBot ("bot" implying "robot") seems more mechanical than other Synths found throughout the universe. It appears to sport several cogwheels and pistons on its body, more in line with the "Combine recycling human materials" mood of the very early Half-Life 2 storyline. Overall, the TBot design appears to be much closer to the "mech" from the cut Weather Control story fragment, making it a likely an ancestor of larger, two-legged Synths like the Combine Synth Elite Soldier or the Combine Super Soldier.

"TBot2"
A variant of the TBot1, with green eyes, the colour of the robot is unknown, because the TBot in concept art is obscured.
All existing TBot 2 files were deleted from the retail version of HL2.
"Alyx Vignette"
A story fragment from Raising the Bar is set at the start of the Air Exchange chapter and has Gordon involved in a train wreck. Alyx, accompanied by her pet Skitch, encounter Gordon before being attacked by "tripods" (i.e. Striders) and "Combine Elite": tall, metallic shapes making muffled, almost silent movements. The description does fit that of the Combine Super Soldier (named "Combine Elite" in Raising the Bar[5]) while also vaguely matching the Combine Synth Elite Soldier, another elite Combine unit. Also stated in the book, the Elite was turned into the humanoid unit seen in the final version.
Trivia
- The term "Synth" relates to words such as "synthetic", "synthesis" or "synthetical". A "synthetic" element is "made artificially by chemical synthesis";[6] a "synthesis" is "the combining of separate elements or substances to form a coherent whole";[7] and a "synthetical" element is the combination of "separate elements to form a coherent whole".[8] The term "synth" could therefore be interpreted as a short for "synthetic". In a general science fiction sense, "synth" is often synonymous with words like "android", "robot" or "artificial (human)", namely in IPs like those belonging to Philip K Dick and the Fallout series of video games.
- It could be argued whether Hunters are Synths or Cyborgs since they are vulnerable to gunfire and seem to have an integrated armor instead of a full metal body, unlike other Synths. A blood-like substance is observed on hit, also suggesting organic matter. This also shows that all Synths are cyborgs rather than robots.
- It is unknown if Synths are the only species/force used within the Combine or if other kinds of creatures exist within the Union.
