 Shadow Walkers is a highly suspenseful story of a group of lab technicians and military personnel who awaken in a subterranean laboratory with no memory of who they are. They quickly discover that they are sealed in, with only one way to get out alive. They must travel deeper into the underground facility to an escape tunnel that leads to the surface. Hindered by the fact there is only limited electrical power, they struggle through the darkness where they uncover a hive of genetically mutated creatures that stalk them from the shadows. Bred for combat, these monsters are endowed with razor sharp talons and rows of jagged teeth capable of ripping a man apart. While avoiding danger at every turn, they begin to regain their memories, discovering the origin of the deadly creatures and the part they played in their creation.
