Her Interactive and SEGA of America have announced that the first Hardy Boys game for the Nintendo DS, The Hardy Boys: Treasure on the Tracks, is now available at stores nationwide.

“The introduction of Treasure of the Tracks expands our audience with one of the most well-known and respected brands for boys and girls alike, and is an ideal way in which to introduce ourselves to the Nintendo DS audience,” said Megan Gaiser, president and CEO of Her Interactive Inc.

Traveling by train across Europe, Frank and Joe Hardy follow the mysterious trail of the Romanov family treasure through historic cities like Vienna, Paris, Prague, Warsaw, and St. Petersburg, trying to unlock the century old secret that surrounds the Romanov family. Things get decidedly mysterious on board the Royal Express as players explore train cars for clues, interview passengers and solve interactive puzzles as they hunt down the lost treasure.
