On the Valve developer wiki, it is referred as a "Cavern dweller." There is an unused alternate texture for the Antlion Guard in the Half-Life 2 and Episode One game cache files, giving the creature a blue-color skin. Though this could simply be an error, it may indicate that this particular specimen is a female of the species, or that possibly all Antlion Guards are female. Repeat: Primary target has tactical C&C over biotics," implying that Overwatch has never encountered a human utilizing the aid of Antlions before.Īn image caption on the official Episode One site refers to an Antlion Guard seen in a screenshot as an "Ant Lion Queen", although it bears no difference in appearance from other normal ones (Alyx calls them Guards). Combine Overwatch soldiers will flail about for several seconds if a pheropod is thrown directly at them, due to the powerful aromatic pheromones emitted upon contact.Īs Gordon progresses into Nova Prospekt, a Combine Overwatch soldier can be heard saying, "Warning, primary target is, uh, engaged in, uh, command and control tactics with biotics. It's not clear where Gordon gets replacements, as the weapon has unlimited ammo. The pheropods (called "bugbait" by the Rebels) can be used to send commands to the Antlions to follow Gordon by squeezing them or attack his enemies by throwing them. When Gordon encounters additional Guards later in the game, the Antlions under his command refuse to approach. To Antlions, the pheropods identify Gordon as a Guard and therefore do not attack. After its defeat, a Vortigaunt extracts its pheropods and gives them to Gordon. While traveling along the coast, an encounter ensues with a Guard. Their primary attack is a charging head butt, which can also turn any loose objects within the Guard's line of sight into deadly projectiles if the Guard hits them. Unlike the smaller Antlions, they cannot jump or fly, but make up for this by being much faster. Antlion Guards File:HL2Antlionguard.jpgįar larger and stronger, Antlion Guards (with the binomial name Myrmidont giganticus ) have command and control over other Antlions. Similar fictional creatures include the graboids of the film Tremors, which react in a similar way to loud noises such as explosions, and the arachnid warriors in the film version of Starship Troopers.Īn Antlion Guard. However, while the use of Thumpers to produce powerful vibrations attracts Sandworms, Antlions are repelled by the very same tactic, possibly experiencing sensory overload or pain in their presence, due to their sensitivity to vibration. The behavior of Antlions in respect to sound, vibration and aversion to water is analogous to that of Sandworms in the Dune universe. Antlions are the only enemies in Half-Life 2 that gib rather than becoming ragdolls if killed with a strong weapon. The Antlion group mentality makes up for their lower health totals: an individual Antlion is relatively easy to kill, but its friends will attack while the player is occupied. It is also possible to flip the Antlions over with a burst from the Gravity Gun, allowing for a quick escape. Refuge may be sought in water, since Antlions cannot swim and quickly drown when they come into contact with it. Unless covered, burrows continually spawn Antlions to replace those killed. Half-Life 2: Episode One introduces the concept of Antlion burrows, essentially large holes in the ground from which Antlions spawn. If the player is still on sand when one is killed, another will spawn to replace it. In Half-Life 2, a swarm of five Antlions will usually emerge when the sand is disturbed. The Combine refer to Antlions as "virals," "biotics," or "exogens", as a soldier can be heard mentioning a "full biotic overrun" of the Nova Prospekt facility however, the term biotic may also be a general term used by the Combine for any hostile life form, including Antlions and headcrabs. Once on the surface, Antlions can fly short distances to rapidly approach their prey.

This makes it possible to safely venture through Antlion territories by walking solely over foreign items placed on the sand, or by walking across rocks. Antlions sense a victim's presence via vibrations transmitted through loose soil or sand.

Their aggression is not limited to humans or the Combine, and they will attack other xenofauna such as headcrabs. They usually hide under the sand, waiting for anything to venture near, at which point they quickly surface and tear it apart.

Antlions live in underground colonies, typically situated in sandy areas such as beaches.
