The HL2 Headcrab

Overview

Headcrabs are a Xenian species that began appearing in the Black Mesa Research Facility after the resonance cascade.

Appearance

Headcrabs appear small in size, about the size of a basketball. They have a fleshy body, two short hind legs, two long claw-like appendages in the front, and a mouth on their underbelly. The Black Mesa Team will not be modeling their own headcrabs, but use the stock Half-life 2 models. This also includes the headcrabs on the zombies themselves.

Behavior

Headcrabs are Omnivores. It is unknown what their primary food source is on Xen, but on Earth they tend to seek out any meat that is near them, from humans to crows.

Headcrabs will waddle on their four limbs for basic transportation. After locating a victim they will leap through the air in an attempt to reach their victims head. If the headcrab is successful in reaching their victim's head, they will latch on, rendering the victim unconscious and eventually robbing the victim of the capability of conscious thought, thus transforming them into a dangerous Zombie.
