Primitive War 1 (Unabridged‪)‬

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. When the casualties mount, the men of Vulture Squad must abandon their human nature and give in to their savage instincts to survive...the Primitive War.
