Description[]
Fueled by an insatiable hunger, driven by a consuming madness, the pack ravaged the countryside, killing for sport - killing for food.
Possessed of an unnatural intelligence, skilled at stalking and attacking, they chased and devoured their human prey with the icy, snarling efficiency of the perfect killing machine.
Once they had been pets, now they were man's worst enemy - and their numbers were swelling.
BEWARE THEIR SLAVERING JAWS OF DEATH!
