Antlion guards usually attack alongside groups of Antlions who they command via pheromones emitted from the 'Pherapods' on their bodies and attack by charging aggressively, in a straight line. They are beige and red or light blue in colour, have four legs and large top sections. Antlion GuardsĪntlion guards appear only a few times throughout the Half-Life games, in large, open areas. Later on in Half Life 2, Gordon Freeman receieves the ability to control a pack of antlions that can attack enemies for him. However Common Antlions can be easily killed and even temporarily flipped over by the Gravity Gun. In some areas of the Half-Life games these Antlions will spawn infinitely unless certain areas are avoided or their spawn point is otherwise blocked. This species of Antlion live in packs and attacks aggressively, ignoring everything in their path and often lunge at opponents and using their legs and teeth to scratch at them. They are beige-green in colour, with elongated quadrelateral-shaped backs, four pointed legs and triangular heads. These are by far the most common variety of Antlions. Antlions do not have eyes and so rely on their sense of smell and vibration. These creatures likely originated on the Vortigaunt's home world and lived in subterranean colonies.

The smallest of these ferocious bugs are the size of small dog, and the largest are bigger than a tanker truck. Antlions are extra-dimensional alien insectoids deposited on Earth from Xen by portal storms that occurred in the aftermath of the death of the Nihilanth.
