Secret Files: Tunguska (German: Geheimakte Tunguska) is a 2006 graphic adventure video game developed by German studios Fusionsphere Systems and Animation Arts and published by Deep Silver for Microsoft Windows, Nintendo DS, Wii, iOS, Android, Wii U and Nintendo Switch. The game is the start of the Secret Files trilogy, with a sequel, Secret Files 2: Puritas Cordis, being released in 2008.
Gameplay
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. Unlike games in the Broken Sword series, however, it is not possible for the player to lose or get into an unwinnable situation. There are also a few parts of the game where players must switch between the main character, Nina Kalenkov, and her boyfriend Max Gruber, to progress.
The Wii version of the game exclusively allows the player to connect a Nunchuk to a Wii Remote and use its analog stick to directly control character movement and also supports cooperative multiplayer in which a second player uses another Wii Remote to easily point out anything that could be crucial to progress.
Plot
One night, Nina's father, Vladimir Kalenkov, in his office in a museum in Berlin, is suddenly attacked by a figure in black robes who seemingly possesses psychic powers. A while later Nina enters the office but finds the place ransacked and her father missing. She calls the police but they refuse to help due to bureaucratic reasons, but afterwards, detective Kanski arrives at the place. Nina is finally offered help by Vladimir's assistant, Max Gruber. She returns to her and her father's apartment to find it ransacked too and she is knocked unconscious being attacked from behind. In the apartment she finds clues about someone named Oleg Kambursky, who is living nearby and had been contacted by her father and the latter wanted to see him again. After finding his address, Nina goes to meet him, but he denies knowing her father. Nina afterwards overhears Oleg making a frantic telephone call to someone mentioning Vladimir and Tunguska and she decides to talk to Max Gruber about the events and ask him about Tunguska. As Nina and Max go to Vladimir's office, they are intercepted by Detective Kanski holding a gun, but they are saved by Oleg who knocks Kanski unconscious and they all escape. Afterwards Oleg explains everything to them.
Apparently a cataclysmic explosion of unknown causes occurred in Tunguska in 1908 and an unnatural plant growth was noted in the area afterwards. Also a giant object made of an unknown material was found there, but was vanished some time later. Vladimir Kalenkov was the leader of a secret expedition in the same region in 1958 along with Oleg Kambursky and some other scientists, to study the plant growth. They also found a fragment made from an unknown material and Vladimir, in his “Kalenkov Report”, proved that the object was from extraterrestrial origin, but the results were kept hidden by higher up and they were forbidden to continue any further. Despite that, Vladimir organized another expedition in 1977 with Cuban Manuel Perez and Ken Morangie (an Irish biologist), to search for more fragments but they were intercepted. At present time, Oleg has found out from a contact of his (Sergei) that a research station was built in the Tunguska region and a train is departing from Moscow and is due to transport many scientists, who had participated in the first expedition, to that station and not all of them voluntarily, and maybe Nina's father is among them. Oleg offers to take Nina by his plane to Moscow, while Max stays behind in case Vladimir appears, and she eventually manages to get on board the train. She doesn't find her father on board, but she finds documents about the “Kalenkov Report”. Also, she reads that thanks to this report, the scientists learned how to manipulate the behavior of animals, applying different levels of radiation.
