In the original game, Vortigaunts were enslaved by the Nihilanth and used as workers and drone soldiers. īrief 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. When faced with a superior enemy, Vortigaunts will often retreat, and if possible, group together with other Vortigaunts to form a stronger force. Throughout the Half-Life series, they can be seen in pairs or groups, and are capable of developing intelligent strategies. Vortigaunts are very intelligent and social creatures. Vortigaunts have a slightly hunched posture, and their faces are dominated by a large eye with a maroon Sclera and a Heterochromic red-yellow iris with a yellow pupil, surrounded by three smaller eyes.Īnother interesting feature of the Vortigaunts is that they can speak English fluently, albeit with a strange accent and some sort of speech impediment when using S's and R's.

Vortigaunts have mottled green-brown skin, sharp teeth, and clawed hands. They are capable of using their arms to run like a quadruped, to cover large distances. However, Vortigaunts are also shown able to use their green energy through this third arm in Half-Life: Alyx.

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