Primitive War

At the height of the Vietnam War, a search and rescue team known as Vulture Squad is sent to an isolated jungle valley to uncover the fate of a missing Green Beret platoon. As Vulture Squad hunts through the primordial depths of the valley, they discover ancient horrors that not only threaten to unravel their minds, but to end their lives, as well.

A year has passed since the American Forces quarantined the primeval valley, and a new Special Forces team known as Stalker Force has been created to track the most dangerous dinosaurs of all time—the utahraptors—and destroy them. The mission proves to be more than the fledgling team can handle when they come face to face with mysterious new predators, clandestine para-military operatives, and a cunning alpha male utahraptor known as Sobek; the nihil river god.

During the most turbulent years of the Cold War, the elite dinosaur-hunters of Stalker Force are tasked with finding and killing a horrific plague-carrying utahraptor known as Xipetotec. Their search for Xipetotec takes them across the earth, from the battlefields of Vietnam to the dark heart of Africa. This odyssey is intertwined with the spiritual decay of a young Vietnamese mercenary known as 'the Panther'. As dinosaurs spread across the world, people from all walks of life must learn to survive... the Primitive War.
