Just Be Cool: Stalker

Believed to be the result of a failed experiment in an attempt to genetically modify humans' skin to adapt to the increasingly arid climate, Stalkers get their name from their tendency to hunt their prey from the shadows. Large scaly structures on their skin resemble the canyon rocks they use as camouflage as they patiently wait until the right moment to strike, attacking almost always in packs in a seemingly unrelenting fashion. Feared by many as the "desert boogeyman", Stalkers are fast melee attackers that swarm their prey before mauling it to death. It'd be best to keep your distance.
