The Adventure Company showed off Secret Files: Tunguska at E3 2006. This point-and-click adventure game follows the adventures of a character named Nina who's searching for her father, who disappeared after a research expedition to the Tunguska region of Siberia, where a meteor or comet strike destroyed a huge swath of land in 1908. After teaming up with Max Gruber, a colleague of her father's, Nina travels around the world in an attempt to track down her father, as well as discover the truth behind what occured in Tunguska.
Nina's quest for the truth will entail interacting with her environment, picking up inventory items, and finding out where to use them, as well as speaking with numerous NPC characters. Graphically speaking, Secret Files looks pretty sharp at this point, with some gorgeous prerendered backgrounds for you to explore and search.
Secret Files: Tunguska is set for release in August of 2006. Stay tuned to GameSpot for more details on the game as they become available.
