An elite team of mercenaries is chosen to carry out a covert operation deep in a former Soviet state. They must first battle the ferocious armed militia at ground level before descending through a maze of tunnels inhabited by dark, menacing creatures. When the team members arrive at an underground laboratory, they discover the purpose of their mission: A genius scientist has been genetically splicing alien DNA with human, and the results of this revolutionary work must be secured. The soldiers must protect and save the specimens whilst avoiding the threats of multiple predators, both human and otherwise.
