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.

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.

Unlike games in the Broken Sword series, however, it is not possible for the player to lose or get into an unwinnable situation. The game features a 'snoop key' tool, which highlights all interactive objects on screen and assists in finding small, easily overlooked objects. The game is viewed from a third person perspective and uses a classic point and click interface. The game is the start of the Secret Files trilogy, with a sequel, Secret Files 2: Puritas Cordis, being released in 2008. 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.
