After the Jungle Hunter's ship landed in Guatemala, it's not long before American military personnel are found killed, skinned, and hanging from trees.
Alan "Dutch" Schaefer gets called in with a team of mercenaries to intervene. The Jungle Hunter cloaks itself and runs along the tree canopies, hidden, as it takes out the mercenaries one by one, finally culminating in a head to head battle with Dutch.
Dutch manages to outsmart the Jungle Hunter using guerilla tactics. Once it was bested, it self-destructed, nearly taking Dutch out with it.
