Secret Files: Tunguska (used)

On June 30, 1908, an explosion 2000 times more powerful than that of Hiroshima took place in the Tunguska region in central Siberia, destroying 6,000 square kilometers of forest.

Witnesses saw an object fall from the sky and a column of smoke several kilometers high. It is reported that several consecutive nights were abnormally clear after this phenomenon throughout Europe.

Until today, this phenomenon remains unexplained. YOU will have to shed light on this event in a race against time that will take you to the ends of the earth. Prepare for the worst.
