The '''Vortigaunts''' (taxonomic designation '''Xenotherium subservilia''',http//web.archive.org/web/19990221220053/http//ogr.com/specials/monsters/halflife_monsters.shtml Half-Life Monster of the Week Feature on OGR.com or "Subservient Alien Beast"), formerly known as '''Alien Slaves''' or '''Xen Slaves''', and affectionately known as "'''Vorts'''" by their allies, are a sapient alien species found throughout the Half-Life universe|''Half-Life'' series.

Long before the Black Mesa Incident, the Vortigaunts' homeworld was invaded by the Combine, forcing the survivors of the invasion to flee to Xen. When the Black Mesa Incident occurred, their master, a being known as the Nihilanth, viewed the rift that opened as a chance to escape, and directed the Vortigaunts to invade Earth.  

Following the death of the Nihilanth, the Vortigaunts have chosen to ally themselves with the human-led Resistance in its bid to overthrow the Combine rule of Earth.''Half-Life 2''

== Overview ==
=== Physiology ===
In appearance, Vortigaunts are somewhat humanoid, with two legs and two arms and an additional third arm protruding from the chest. This extra limb is a feature also found in other bipedal, sapient species from Xen, including the Alien Grunt and the Nihilanth. This similarity, along with other shared features such as red eyes and back-jointed legs, is strongly suggestive of a common ancestry with other intelligent Xen life forms. Apparently, this third arm is used for feeding, as both Vortigaunts and Alien Grunts are often seen bending over slain victims, feeding on them. 

Vortigaunts have WikipediaMottle|mottled green-brown skin, sharp teeth, and clawed hands. Vortigaunts have a slightly hunched posture, and their faces are dominated by a large, single eye with a maroon WikipediaSclera|sclera and a WikipediaHeterochromia|heterochromic red-yellow iris with a yellow pupil, surrounded by three smaller eyes. All four eyes are actually multiple openings to a single eye surface, as noted on a white board in Questionable Ethics. They also have a navel, two rectums, and four nipples, suggesting that Vortigaunts reproduce in a similar fashion to Earthly mammals. 

Another interesting feature of the Vortigaunts is that they have no tongue or teeth on their lower jaw,{{Fact}} yet they can speak English fluently, albeit with a strange accent and some sort of speech impediment when using S's and R's.''Half-Life 2 Episode One''''Half-Life 2 Episode Two''

=== Intelligence and culture ===
FileVortigaunt-canals.jpg|left|thumb|150px|A Vortigaunt in the City 17 canals.

Vortigaunts are very intelligent and social creatures. Throughout the ''Half-Life'' series, they can be seen in pairs or groups, and are capable of developing intelligent strategies. When faced with a superior enemy, Vortigaunts will often run away, and if possible, group together with other Vortigaunts to form a stronger force.''Half-Life''

FileC3a2a0001.jpg|right|thumb|250px|Vortigaunts "communicating" over a corpse in Black Mesa's Lambda Complex.

Brief glimpses into  the Vortigaunt culture can be gained by occasional speeches given by them in ''Half-Life 2'', and in scenes during the original ''Half-Life''. In the original game, Vortigaunts were enslaved by the Nihilanth and used as workers and drone soldiers. Based on comments by the All-Knowing Vortigaunt, it seems that the species has endured slavery for many generations ("''We have endured these chafing bonds for eons, yet a single moment of further servitude seems intolerable!''" as he says) and enforced servitude appears to have formed the bedrock of Vortigaunt history and culture up to the events of the first ''Half-Life''. In ''Half-Life 2'', Vortigaunts make occasional references to their species' culture. 

=== Communication and the "Vortessence" ===

Vortigaunts possess their own native form of vocal communication, which, in ''Half-Life 2'', is referred to as "flux shifting", and can be heard in rare instances when two Vortigaunts are engaged in conversation. According to the Vortigaunts, flux shifting cannot be understood by "those whose Vortal inputs are impaired", which may suggest that other inaudible components are involved, perhaps explaining why it is incomprehensible to humans. One example of flux shifting occurs during the aftermath of the first Hunter attack in ''Half-Life 2 Episode Two'', when the Victory Mine Vortigaunt|Vortigaunt that saves Alyx Vance|Alyx calls out over an immense distance to communicate with its kin, using two short but apparently highly descriptive calls.

By the beginning of ''Half-Life 2'', Vortigaunts have learned to speak at least one human language, which, in the English language version of the game, is predictably English (in some international versions of ''Half-Life 2'', Vortigaunts speak the appropriate language for the country of the game's release, e.g. in the French language version of the game, the Vortigaunts speak French). However, when speaking English, Vortigaunts use archaic words and syntax, tending to use outdated, even Shakespearean phrases. In the subtitles, flux shifting is called "Vortigese."

Vortigaunts believe in a binding life-force which they call the "Vortessence". Due to their use of this force, which remains untapped by humans ("''We are a tapestry woven of Vortessence. It is the same for you if only you would see it.''", as said by the All-Knowing Vortigaunt), the Vortigaunt species can communicate with one another telepathically. They believe Vortessence is the fabric of the universe, made of "vortal cords", of which everything is woven (and therefore everything is connected). The Vortigaunts are able to read and control this force for their electrical powers, nearly hive-mind telepathy and, likely, their ability to take power from objects. They can use their powers coupled with "the extract" of Antlion larvae to bring the dead back to life (however, it is shown in ''Half-Life 2 Episode Two|Episode Two'' that they cannot do this alone).The ''Half-Life 2 Episode Two'' chapter ''Half-Life 2 Episode Two storyline Vortal Coil|This Vortal Coil.

It has been hinted that death is not permanent for a Vortigaunt, and that they might have the ability to "reincarnate" into a new body after death ("''What seems to you a sacrifice is merely, to us, an oscillation. We do not fear the interval of darkness.''" as said by the All-Knowing Vortigaunt).

== Behavior and skills ==
=== ''Half-Life'' and its Expansions ===
In ''Half-Life'', Vortigaunts are common enemies in both Black Mesa Research Facility|Black Mesa and Xen. While they usually attack aggressively, they often become timid when injured, preferring to run away rather than risk further combat and possible death. There is one area in Xen that houses a small number of peaceful Vortigaunts. However, if one is attacked they will become aggressive. Vortigaunts have two modes of attack an energy attack in which they fire powerful green lightning-like energy beams that require a vulnerable period of "charging-up" before being unleashed, and when close to opponents, a rapid and powerful claw attack. Significantly, in ''Half-Life'' all of the Vortigaunts wear green collars and wrist bands. Later events reveal these to be a means by which they are enslaved and controlled by a remote master, the Nihilanth. Vortigaunts often act as support for Alien Grunts, making the Vortigaunts more likely to be able to use their attack, as the player is usually concentrating on killing the tougher Grunts. Throughout the game, the Vortigaunts can be heard taunting the player with what sounds like the word "die", and shouting a word that could be perceived as "Gordon" when the player approaches. Vortigaunts have the ability to use Healing Shower|Healing Showers on Xen. When attacked in their passive state, they may run to a healing shower and heal up before engaging in a fight.

=== ''Half-Life 2'' and its Episodes ===
In ''Half-Life 2'', their electrical attack is far more devastating, as it tends to kill whatever it hits immediately and knocks the target back a considerable distance. Only objects with significant mass can resist being knocked back, such as the Strider (which appears to be fully immune to the beam) and Antlion Guards. These attacks occur twice during the single player game when Gordon's view is restricted by rubble and when the Vortigaunt extracts Pheropods|Bugbait from the Antlion Guard. It is also suggested that Vortigaunts can siphon an opponent's life-force with their energy beam attack, as they are heard saying phrases like "Give over your essence!" or "Empower us!" during some of their attacks in ''Half-Life 2''. In the ''Half-Life'' expansion ''Half-Life Decay|Decay'', the player plays as a Vortigaunt in a Half-Life Decay storyline Attacks (bonus chapter)|bonus mission, and the beam attack does indeed 'steal' life-force from enemies.

The beam attack is revealed fully in ''Half-Life 2 Episode Two|Episode Two'', where a group of Vortigaunts use it to defend an underground outpost from a massive Antlion Half-Life 2 Episode Two storyline Vortal Coil|attack. It is shown to be powerful enough to kill Antlions and Standard Zombie|Zombies, and causes a shock wave strong enough to knock over other nearby foes. Gordon Freeman|Freeman's Victory Mine Vortigaunt|Vortigaunt companion uses this ability to aid him in his attempt to raid an Antlion nest.

The Vortigaunts can now recharge Gordon Freeman|Freeman's H.E.V. suit, if he stands near them, the Vortigaunts in ''Half-Life 2'' can recharge HEV suit to 30 percent power with their blue electrical beam. In ''Episode Two'', the Vortigaunt can recharge the suit to 15 percent and it uses small green balls (3-4 percent per ball).

== Appearances ==
=== ''Half-Life'' ===
Vortigaunts first appear in the chapter ''Half-Life storyline Materials|Anomalous Materials'', during the Resonance Cascade. Several Vortigaunts teleport in from the ceiling of the Sector C Test Labs Lab C-33/a|test chamber, disappearing as they near the floor (one will remain if the Xen crystal|crystal is removed from the Anti-Mass Spectrometer).The ''Half-Life'' chapter ''Half-Life storyline Materials|Anomalous Materials''. A few moments later, when Gordon Freeman is briefly teleported to Xen, he appears in a dark room, with four Vortigaunts standing in a half-circle around him. However, they do not attack him. Later on, in ''Half-Life storyline Consequences|Unforeseen Consequences'', they can be found as standard enemies, and remain so for the rest of the game.

=== ''Half-Life Opposing Force'' ===
Vortigaunts first appear in the ''Half-Life Opposing Force storyline'', when Adrian Shephard blacks out and regains consciousness. He also observes a Vortigaunt killing a fellow HECU marine and is helpless to assist due to his condition.  Later, in ''Half-Life Opposing Force storyline to Black Mesa|Welcome To Black Mesa'', a Vortigaunt is found dead and on its back, with a Combat Knife stuck in it. Afterwards, Vortigaunts appear throughout the rest of the game as standard enemies.

=== ''Half-Life Blue Shift'' ===
Vortigaunts are relatively common enemies in ''Blue Shift'' and Barney Calhoun regularly encounters them as he fights to escape Black Mesa.

=== ''Half-Life Decay'' ===
In the official co-op expansion ''Half-Life Decay'', players who manage to obtain an A rank on all of the regular missions may unlock a bonus mission titled ''Half-Life Decay storyline Attacks (bonus chapter)|Xen Attacks'', where both players play as Vortigaunts. Although short on story, the mission gives some unique insight into the Vortigaunts' role in the Black Mesa Incident. The players control "Drone Subjects" X-8973 and R-4913, two Vortigaunts sent to Earth by the Nihilanth. Both Vortigaunts are able to regain health by damaging objects or enemies.

=== ''Half-Life 2'' ===
FileSweeping Vort.jpg|left|150px|thumb|An enslaved Vortigaunt janitor in ''Half-Life 2''.

In ''Half-Life 2'', Gordon Freeman meets up with the Vortigaunts again. This time, however, they are eager to assist in overthrowing the Combine. In the time between the two games, the Vortigaunts have been freed from their former master, and most remaining on Earth have joined the human Resistance against the Combine. The game also reveals that the Vortigaunts are capable of using their electrical attack productively, in the form of a blue energy stream that can recharge batteries, power electronic circuits, fuse objects together and even power up Gordon's HEV suit. The Vortigaunts credit Gordon Freeman with their freedom, and hold him in high esteem as "The Free-man" (as it was Freeman who slew the Nihilanth and freed the Vortigaunts).

However, not all Vortigaunts have been freed. In the first chapter of ''Half-Life 2'', ''Half-Life 2 storyline Insertion|Point Insertion'', it is possible to catch a brief glimpse of a Vortigaunt working under the Combine. Wearing a collar and armbands similar to those worn in ''Half-Life'', the Vortigaunt is shown slowly and meticulously using a push-broom to sweep dirt and garbage in the City 17 Trainstation while being watched by a Civil Protection|Metrocop. When exploring Nova Prospekt, the player comes across a dead Vortigaunt, wearing collar and armbands, sitting in a restraining chair. Interestingly, this occurs in block A2 about which Overwatch Voice|Overwatch had directed shortly before "De-service all political conscripts in block A2 - prohibit external contact." It appears that the Vortigaunt had died during electrical torture by the Combine, which would explain Alyx Vance's comments that the Resistance's only knowledge of Nova Prospekt is through telepathic communications from Vortigaunts taken there for torture or interrogation.The ''Half-Life 2'' chapter ''Half-Life 2 storyline Prospekt|Nova Prospekt''.

=== ''Half-Life 2 Episode One'' ===
FileGman Vortigaunts prologue.jpg|thumb|200px|A group of Vortigaunts hold back the The G-Man|G-Man at the start of ''Half-Life 2 Episode One|Episode One''. The scene mirrors the Vortigaunts seen during the Resonance Cascade in ''Half-Life''.

In the beginning of ''Half-Life 2 Episode One'', a group of Vortigaunts free Gordon from the G-Man and save Alyx Vance|Alyx from certain death after the explosion of the Citadel's Dark Energy Fusion Reactor|Dark Fusion Reactor, teleporting both of them to the relative safety of the center of City 17, just outside the Citadel - revealing the Vortigaunts may be more powerful than previously speculated, even to the point of challenging the G-Man.The ''Half-Life 2'' chapter ''Half-Life 2 storyline Energy|Dark Energy''.

The purple color of the Vortigaunts at the beginning appears to be a side effect of the filters and lighting used in that scene. The supporting evidence is that during the explosion where Alyx is rescued, the Vortigaunts appear purple-colored and semi-translucent although the rest of the scene is unfiltered and lit with realistic lighting.  Although, it could be that they had all imbibed antlion larvae extract.  It would also make sense as the extract supposedly boosts the Vortigaunts' power by a tremendous amount, enough perhaps, to hold back the G-man for a short amount of time.

=== ''Half-Life 2 Episode Two'' ===
FileVortigaunt mines.jpg|left|thumb|200px|A Vortigaunt in ''Half-Life 2 Episode Two|Episode Two''.

Vortigaunts play a much larger role in ''Half-Life 2 Episode Two''. After a Hunter mortally wounds Alyx and traps Freeman under a collapsed building, Victory Mine Vortigaunt|a Vortigaunt saves the former from being eaten by an Antlion. The Vortigaunt then stabilizes Alyx's condition and carries her to an underground Resistance outpost, where, with the help of three more Vortigaunts, they beat back a heavy Antlion incursion. A Vortigaunt then accompanies Freeman in a quest to harvest the miraculous larval extract of the Antlions to save Alyx's life. The Vortigaunt proves a valuable companion; it kick-starts generators by giving them an electric jolt, its lightning attack damages and knocks over nearby Antlions, and it also charges up Freeman's HEV suit on occasion. Eventually Freeman is able to access the Nectarium, where the Vortigaunt harvests a small quantity of the larval extract. Both Gordon and the Vortigaunt travel back to the outpost and begin a ritual to heal Alyx.

It is at this point the The G-Man|G-Man reestablishes contact with Freeman. He states "...but I had to wait until your... 'friends' laughs slightly were otherwise occupied...", suggesting up until then the Vortigaunts had somehow been keeping the G-Man at bay. He also refers to Half Life when he says "There was a time when their only experience with humanity was a crowbar coming at them down a steel corridor" The Vortigaunts are unaware of the intrusion, and they never mention the G-Man, nor the service they rendered Freeman and Alyx at the beginning of ''Episode One''. 

The Vortigaunt then accompanies Freeman and Alyx a little further on before heading back, mentioning that he and his cohorts are occupied with searching for Combine Advisor pods. Another Vortigaunt, given the name Uriah by Arne Magnusson, aids Freeman briefly later on in the Episode at White Forest.

For gameplay purposes, if Gordon strays too far from Alyx during the course of ''Episode Two'' to some specific places where she cannot reach, the screen briefly shows the text 'The Freeman must proceed with the Alyx Vance, else our struggle is doomed to failure. Those who do not learn from their mistakes are doomed to an endless Vortal Loop.' Then the game reloads (Referencing that those who continue to leave Alyx will keep reloading the game).

== Behind the scenes ==
FileAlien slaves concept.jpg|thumb|250px|right|Early design.

* In ''Half-Life'', Gordon Freeman was originally to win the Vortigaunts over as allies on Xen, then lead them to outright rebellion. This plan proved impractical but was reused for ''Half-Life 2'', although Vortigaunts are benign when first met at the start of the ''Half-Life'' chapter ''Half-Life storyline'', until a Controller forces them to attack.

* In the playable Half-Life 2 Beta|''Half-Life 2'' Beta, Vortigaunts have a voice closer to that of their ''Half-Life'' voice, very similar to that of wcstarwarsYoda|Yoda in ''Star Wars''.Playable Half-Life 2 Beta|''Half-Life 2'' Betahttp//www.youtube.com/watch?v=BOTI0BE1ojc Half-Life 2 Beta - Vortigaunt on http//www.youtube.com YouTube

* Friendly fire was also originally to be authorized on ''Half-Life 2'''s Citizens and Vortigaunts, like with the Black Mesa Personnel in ''Half-Life''. The feature can be experienced in the playable ''Half-Life 2'' Beta; upon being hit, Vortigaunts will answer things like "You have given me no choice but to eliminate you", "Let me return your gift", "This pains me" or "Now, I unmake you", although they do not fight back. This is also heard in the final version when attacking Metrocops just after Alyx and Gordon are separated at Black Mesa East. Furthermore, Joe was originally to say "Hey, stop that! The Vorts are on our side, now!" if the player would harm the nearby Vortigaunt in the boxcar.Playable Half-Life 2 Beta|''Half-Life 2'' Beta files

* In the playable Half-Life 2 Beta|''Half-Life 2'' Beta files, a texture of a burned Vortigaunt body can be found, suggesting that burned Vortigaunt corpses were also to be seen, along with citizens', during the course of the game.

* City 17 was originally to be filled with "Vorti-Cells", Combine devices used as stations siphoning power from trapped Vortigaunts.

* If you use the console to create a Vortigaunt with a weapon (npc_create_equipment ''weaponname'') the weapon will be held in the middle of its stomach going right through it.

== Trivia ==
* The Panther Eye, an enemy cut from ''Half-Life'', is very similar to the original Vortigaunt.

* Towards the end of ''Half-Life'' (in the chapter ''Half-Life storyline''), there are many Vortigaunts working. Although they are aware of Gordon's presence (they sometimes even outright stare at him), they are not attacking him, possibly as a way to rebel against the Nihilanth. Later on, they resume their normal behavior in the presence of Alien Controllers.

* It is interesting to note that despite the Vortigaunts' entity name being alien_slave in Half-Life and its expansions, the entity name monster_vortigaunt will also spawn them. The game files refer to them as islave, though it is unknown why. However, given the fact that they were enslaved by the Nihilanth, the developers may have chosen to use these names. 

* In the ''Half-Life'' mod ''http//www.moddb.com/mods/point-of-view Point of View'', one can play as a Vortigaunt during the Black Mesa Incident. The PlayStation 2 version of ''Half-Life'' also allows the player, through the use of cheat code, to play through the game as a Vortigaunt from the first level to ''Xen'' when the game ends earlier than in the normal version.

* The smoother, shinier and slug-like Vortigaunt appearance originally introduced in ''Half-Life 2 Episode Two'' have been added into ''Half-Life 2'' and its Half-Life 2 Episodes|episodes in ''The Orange Box'' as part of a retcon.

* Despite being part of the Resistance, some Citizens still distrust the Vortigaunts, as can be heard in a rebel safehouse during ''Half-Life 2 Episode One|Episode One'' or in Episode Two (by spawning a Citizen).

* The Vortigaunt's appearance and attack style are very similar to that of the Imp, from the ''Doom'' series.

* In Episode 2 of Half-Life 2, in the scene where the Vortigaunts are healing Alyx, the Vortigaunts prove to be strikingly similar to the Nox http//stargate.wikia.com/wiki/Nox from the popular Stargate SG-1 http//stargate.wikia.com/wiki/Stargate_SG-1 television series where they both can heal and revive the deceased with a small group and cannot use any other abilities (The Nox cannot remain invisible and the Vortigaunts cannot keep G-man at bay) while healing.

* Many Vortigaunt lines seem to refer to the actual player of the game, i.e., "Far distant eyes look out through yours." It should be noted that these lines could just as easily refer to the G-man, or whoever his "employers" may be.

* In Episode 2 of Half-Life 2, when climbing out of a deep pit with water at the bottom, Victory Mine Vortigaunt says, "''No pit is complete without a Freeman coming out of it.''"  This line is identical to one of the lines stated by The All-Knowing Vortigaunt.

* In the original ''Half-Life'' the places Vortigaunts hit with their electrical attack left burn marks. This was removed in ''Half-Life 2''.

*In ''Half-Life Blue Shift'', there is a bug after Barney Calhoun activates the Xen triangulation device, if the player touching a Vortigaunt during its dying animation, it will kill the player instantly.

*The Vortigaunt in ''Half-Life 2'' have slower recharge time before they can fire his beam, however they can attack enemies with his claws like in ''Half-Life'', and a foot stomp when approaching a Headcrab at point blank, they appear be more aggressive (on par level in ''Half-Life''). However, in ''Episode Two'', their recharge time is near instant, and a green energy ball can be seen on his hand when fire his beam and their beam is much lighter color compared to the Vortiagunt in ''Half-Life 2'', they have faster attack rate and some special instant kill attack, also unlike the Voritgaunt in Half-Life 2, they can strafe while charging the beam that otherwise cannot be done in ''Half-Life 2''. However, the Vortigaunt cannot attack enemies with his claws in normal way or stomp on the Headcrabs at point blank. But when surrounded by Antlions, the Vortigaunt can use his larger, more powerful shokwave that can kill all Antlions within the range, these Vortigaunt appear to be sightly less aggressive.
