About Secret Files: Tunguska
Secret Files: Tunguska is a mystery adventure about investigating the 1908 Tunguska explosion and uncovering a global conspiracy. You race against time and follow the investigation to far-flung parts of the world, testing your detective skills amid cover-ups and corruption.
The Tunguska mystery
On 30 June 1908, an explosion in the Tunguska region of Central Siberia felled more than 6,000 square kilometres of trees. Its energy was equivalent to 2,000 Hiroshima bombs, and it could be heard up to 1,000 kilometres away. Witnesses described a long object falling from the sky in blue-white light, followed by a column of light 20 kilometres high and a black, mushroom-shaped cloud. For the next three nights, it was reportedly bright enough across Europe to read a newspaper outdoors. What happened remains unknown.
Investigation and presentation
You explore 80 detailed, atmospheric pre-rendered backgrounds, with rain and snow among the weather effects. The game also features full-screen cinematic videos for its introduction and cut-scenes, and 25 rendered 3D characters to interact with.
