On June 30th, 1908 a mysterious explosion took place over the Tunguska River in Siberia, Russia that wiped out trees and wildlife for over 800 square miles. To this day it remains the largest “impact event” in our planet’s recorded history. In the years that followed, dozens of scientific expeditions to the site attempted to explain the disaster but failed to come to any conclusions. In the mid-1940s however, a team of scientists from the Russian secret service visiting the site stumbled upon the wreckage of an alien spacecraft containing technology that far exceeded our own. In the years that followed, the KGB set to work harnessing this mysterious new power source and created a new secret weapons program - The Division of Advanced Weaponry or “O.S.O.”
