Today marks a milestone in the 80 year history of the Hardy Boys, as their first adventure on the Nintendo DS, Treasure on the Tracks, is now available in stores throughout North America.

Treasure on the Tracks finds Frank and Joe Hardy on a train across Europe following the mysterious trail of the fabled Romanov family treasure. Their adventure on the Royal Express takes them to cities such as Paris, Vienna and St. Petersburg, and along the way they must interview passengers and explore train cars for clues to help them find the lost treasure.

Treasure on the Tracks will be sold in major retail outlets, as well as Her Interactive’s own online store (and note that DS games are not region-restricted). For more details about the game, be sure to read our recent hands-on preview.
