Secret Files: Tunguska (original German title Geheimakte Tunguska) is a classic point and click adventure game by Fusionsphere Systems and Animation Arts. Released on the PC in the last quarter of 2006, the game was praised for its graphics, although some critics noted the weakness of the script and dialogues.
The games feature the same storyline but with controls fitting both systems (i.e. motion controls for Wii and stylus control for DS).
On May 26th, 2010, Aeropause Games announced that The Secret Files: Tunguska would finally be released for the Nintendo Wii and Nintendo DS in the United States on June 30th, 2010.
