What I have been working on

 

Yard mutts, a robotic hyena that guards and scavenges for metals in the wastelands of a new dystopian reality. 

They aren't exactly important to the real storyline of the horror game but a creature that the player will have to escape from and may have the ability to befriend at some point in the game. 

Yard mutts mainly roam around the wastelands, if a player encounters the yard mutts they will be hunted down and torn to bits. Their jaws can unhinge and have retractable teeth that depending on which zone of the wastelands, the teeth can inject a hallucinogenic poison.

The hyenas do have the ability to have children but not in the traditional sense. They are made with the basic neurological makeup of a real, non-robotic hyena. They mate for life and have offspring by using parts from the rummage in the wastelands and building their children.
