Nina Kalenkow, a lovely woman living in Berlin, Germany, arrives at her father’s office at the Museum one night to discover he has vanished without a trace. She resolves to look for him after seeing the police department’s incompetence in handling the issue.
Nina is introduced to a conspiracy between governments and secret organizations from that point on, with the help of one of her father’s colleagues, the young Max Gruber, about the vast and unexplained explosion that occurred in 1908 in the Tunguska Region of Russia, which her father was investigating. The adventure will lead them worldwide in pursuit of clues that will finally uncover many secrets as they get closer to Nina’s father. Nina is the main character, but Max can also be controlled sometimes.
Secret Files: Tunguska is a conventional third-person point-and-click adventure game featuring pre-rendered scenery, 3D models of the actors, and CGI animations for specific moments. Important clues are recorded in a journal while playing. The inventory is displayed at the bottom of the screen; picking one item and hovering it over other things or locations will reveal whether or not the item has a use. Furthermore, if “Help” is activated in-game, pressing a button in the bottom right corner shows the location of all on-screen things Nina can examine.
