Vortigaunts, formerly known as Alien Slaves, are sapient aliens.

Their native homeworld is Xen, from where they were enslaved and then forced to lead an invasion of Earth following the Black Mesa Incident, under the direction of the Nihilanth. Following the death of the latter, they have as a species chosen to ally themselves with the human-led Resistance in its bid to overthrow the Combine rule of Earth. They serve as frequently encountered enemies in Half-Life and allies in its sequels.

Physiology and BiologyEdit

In appearance, a Vortigaunt is roughly humanoid with two legs and two arms, but has an additional arm protruding from its chest. This extra limb is a feature also found in the other bipedal, sapient species from Xen, including the Alien Grunt and 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 lifeforms. Apparently, this third arm is used for feeding, as both Vortigaunts and Alien Grunts are often seen bending over slain victims while feeding off of it. Vortigaunts have a mottled green-brown skin, sharp teeth, and clawed hands. Vortigaunts have a slightly hunched posture, and their faces are dominated by a large, single red eye, surrounded by five smaller eyes. Closer inspection reveals that the smaller "eyes" are simply additional openings that lead to one gigantic eyeball.

Intelligence and culture Edit

Vortigaunts are very intelligent and social creatures, and often display these traits. Throughout the entire Half-Life series, Vortigaunts are often seen in pairs or groups, and are capable of developing intelligent strategies. When faced with a superior enemy, Vortigaunts will often run away from the scene, and if possible, will group together with others to form a stronger force. Vortigaunts possess their own method of vocal communication, which, in Half-Life 2, they can be heard using and referring to as "flux shifting". This method of communication involves both speakers vocalizing at the same time, which separates it from all known human languages. 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. Another explanation is that they are subtly suggesting - via the use of the word 'impaired' - that the senses of humans are not quite as 'advanced' as theirs.

By the beginning of Half-Life 2, however, Vortigaunts have learned to speak at least one human language which, in the English language version of the game is, predictably, English (in international versions of Half Life 2, Vortigaunts speak the appropriate language for the country of the game's release, i.e.: in the French language version of the game, the Vortigaunts speak French). The Vortigaunts' use of English is slightly strange, however, as they use archaic, even Shakespearean, words and grammatical structures which are largely obsolete amongst present-day human speakers. It is not known whether this is a lack of understanding or a deliberate choice on their part.

Brief glimpses into Vortigaunt culture can be gained by occasional speeches given by them in Half-Life 2, and in scenes in the original Half-Life. In the original game, Vortigaunts were an enslaved species to the Nihilanth, used as factory workers and drone soldiers. Based on comments made by the "All-Knowing Vortigaunt", it seems that the species has endured slavery for many generations, 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, the free Vortigaunts make occasional references to their species' culture. Vortigaunts have many traditions, including an apparent oral tradition of passing down poetry and songs from generation to generation. They believe in a binding life-force which they call the "Vortessence" (see below), which could be a religion or a popular belief. Due to their use of this force, which remains untapped by the human species, the Vortigaunt species is capable of a form of telepathy, at least amongst their own kind. One particular comment made by a Vortigaunt - "We have lost all dear to us" - suggests that the Vortigaunts have lost their home world and civilization, yet are determined to start again alongside the human race on Earth. There also seems to be a possibility, based on phrases uttered by the "All-Knowing Vortigaunt" that Vortigaunts have a collective consciousness through time and space, and that each moment (Gordon killing the Nihilanth, Gordon's arrival at Black Mesa East, etc.) through time appears to them as one.

It is also worth mentioning that there seems to be a sort of practical afterlife available for Vortigaunts. This is suggested by one of the statements of the All-Knowing Vortigaunt: "What seems to you a sacrifice is merely, to us, an oscillation. We do not fear the interval of darkness." The statement implies that, whenever a vortigaunt dies, it passes into "the interval of darkness", from which it may be able to emerge anew, possibly in a new body or in an astral form similar to the 'purple vortigaunts' of Episode One (Though whenever a Vortigaunt is engaging in the ritual of the use of Antlion Larval Extract it turns a dark purple, just like the Vortigaunts in the beginning of Episode One).

Communication and the "Vortessence" Edit

While they have their own language, Vortigese, Vortigaunts are also able to speak in English (and remark humorously on the etiquette of which language to use in Half-Life 2: "We vocalize in your auditory language as a matter of courtesy. [...] Unless we wish to say unflattering things about you."). They also tend to refer to some characters by adding "the" before their name, such as "The Freeman" or "The Alyx Vance". Vortigaunts can communicate with one another telepathically through a life-force they call the Vortessence.

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 are also able to use the Vortessence to heal wounds to an extent and keep the dying from passing on. They can use their powers coupled with "the extract" of Antlion larvae to bring the nearly dead back to life.

The Nihilanth's powers and enslavement of the Vortigaunts were also gained through control of the Vortessence. In Half Life some of the first Vortigaunts in the game seem to rescue Freeman from Xen using the Vortessence.

The Vortessence is similar to the current human theory of String Theory in that atoms, the basis of matter is made up of "strings" which exist across dimensions because of their extremely small size.

Racial Abilities Edit

In Half-Life and its expansion packs, Vortigaunts are common enemies in both 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. They have two modes of attack: an energy attack in which they fire fairly powerful green lightning-like energy beams that require a vulnerable period of "charging-up" before being unleashed, and when close to opponents, they attack with their claws. 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 controlled by a remote master (the Nihilanth). In Half-Life: Decay, if the player goes to the labs with the aliens being experimented on, collars can be seen hanging on a wall emitting electricity, preventing the player from passing until the power is cut off with the flip of a switch. Vortigaunts often act as support for the tougher Alien Grunts in Half-Life, making them more likely to be able to use their attack, as the player is usually concentrating on killing the tougher Grunts.

In Half-Life 2, their electrical attack is far more devastating, tending to kill whatever it hits immediately, and quite often knocks back its target at 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 singleplayer game when Gordon's view is restricted by rubble and when the Vortigaunt extracts the Bugbait from the Antlion Guard. The only way to see a Vortigaunt in combat is to spawn it with enemies using the console. It is also suggested that Vortigaunts can siphon an opponent's lifeforce 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 Decay, the player plays as a Vortigaunt in a bonus mission, and the beam attack does indeed 'steal' lifeforce from enemies.

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