Deep Silver has released a "Secret Files: Tunguska" demo, giving players a chance to try out the upcoming adventure game by Animation Arts and Fusionsphere Systems.

"On the morning of the 30 June, 1908, hundreds of eyewitnesses observed inexplicable and previously unseen phenomena in the skies above the Tunguska region. Just a few minutes later, several huge explosions with the destructive force of 2,000 Hiroshima bombs shattered the stillness of the boundless central Siberian highlands. In just a short space of time, a flaming inferno reduced everything to dust and ashes, and an unimaginable blast wave snapped trees like matchsticks, hurling the inhabitants of a settlement 20 km away, and their reindeer, through the air. Despite countless expeditions, no crater and no meteorite parts have ever been found; scientists today are still searching for answers. In the Secret Files: Tunguska adventure game, attractive mechanic Nina Kalenkov sets out on a dangerous quest to find her missing father. The search puts her on the trail of the secrets and conspiracies that surround the Tunguska Phenomenon."

The 575MB demo can be downloaded from 3dgamers, FileFront, Game Guru, or Worthplaying.
