Half-Life Inspired Character Design "Denizen"

"Denizen" is my take on an alien from the world of Xen. It shares the same skin as most other creatures from Xen. "Denizen" is meant to be a sort of guardian of Xen, however it has no means of sensory  input besides touch. "Denizen" must repurpose  other creatures as its means of gathering information. In this case, the discarded body of a Headcrab zombie provides it with eyes and ears which it is able to attach to its own brainstem and use to see and hear.
