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.
Ports to the Wii and Nintendo DS platforms were released in May 2008. A sequel, Secret Files 2: Puritas Cordis, was unveiled at the 2007 Leipzig Games Convention.
The game is centered around the Tunguska event and explores its cause. The main protagonist is Nina Kalenkov, a Russian girl living in Berlin, whose role is to uncover the mystery behind the disappearance of her father, who was involved in a secret scientific project concerning the Tunguska region in Siberia. At times, the role of the player-controlled character switches to Max Gruber, who is a German scientist, and Nina's father's colleague.
The game is viewed from a third person perspective and uses a classic point and click interface. The game features a 'snoop key' tool, which highlights all interactive objects on screen and assists in finding small, easily overlooked objects.
The game occasionally breaks the fourth wall. For example, when Nina is asked to carry a bucket of water whose handle has come off, she makes light of adventure gaming cliches:
"Without the handle it's hard to carry. Some colleagues of mine would say: 'that's not possible'. 'that won't work'. 'you can't do it like that."
On the 13th June 2007, Deep Silver announced it would be bringing the game to both of Nintendo's platforms. In an interview with Eurogamer, a spokesman said:
"We chose to do it for a couple of reasons. Firstly to explore the control methods of the Wii and DS, which we find very interesting, and secondly because we feel the platforms deserve this kind of game."
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 for $19.99.
