Deep Silver has released a new trailer for Secret Files: Tunguska for Wii and DS, a game based on the true but mysterious story of the 1908 Siberian explosion. Everybody could see it from a distance, but no one really knew what was going on. In the game, new secret documents are discovered which prove the meteorite theory wrong. You play as Nina (though there will be a second playable character), whose father, a scientist, has gone missing. Secret Files: Tunguska for Wii and DS will hit the store shelves this October.
