Zombie, Half-Life Wiki

A Zombie is a common enemy featured in the Half-Life series. It is the result of a Headcrab attaching to the head of a human and taking control over its victim's body, this incapacitates the host, and renders them a "Headcrab Zombie," or a "Necrotic", as they are referred to by the Combine Overwatch. Ordinary Zombies are often referred to as Standard Zombies to distinguish them from the other types of Zombies, such as the Gonome, the Fast Zombie, the Poison Zombie, the Zombine, and the Armored Z
