"On June 30, 1908 an explosion with the combined power of 2,000 atomic bombs rocked the region of Tunguska wiping out over 2,300 square miles of trees. The explosion could be heard from 600 miles away. Eye witnesses say that they saw a large object fall from the sky which was illuminated in a bluish-white light. A dark mushroom-shaped cloud was followed by a 12 mile high column of light. To date, what happened on that day still remains a mystery… Prepare yourself for an unforgettable adventure, as you race against time to uncover a global conspiracy that will carry you to the far reaches of the world. Do you have what it takes to solve the Tunguska mystery?"
Secret Files: Tunguska is a classic third-person point-and-click adventure game clearly inspired by the old classics, presented against pre-rendered backgrounds with 3D models of the characters, and CGI animations for certain events.
