It's nearly summer, so you know what that means: tornado season. Well, that and a new Nancy Drew mystery, but the two go hand in hand this year, as seen in the demo just released for Trail of the Twister.

In the latest adventure for the popular teen detective, Nancy goes undercover with a group of storm chasers who have experienced a series of suspicious incidents recently. A contest to predict tornado touchdowns has resulted in a fierce competition, so the question for Nancy is whether it's "just bad luck that's plaguing the storm chasers or is someone sabotaging their chances of winning?"

The playable sampler starts off at the beginning of the game, giving a quick glimpse of an imposing twister before sending Nancy indoors to take a tornado quiz and get familiar with her surroundings. But she'll be back on the road soon enough, as you guide her by car around the local streets, careful to avoid other travellers (though thankfully, no flying cows).

The 243 MB demo can be downloaded directly from Her Interactive website, where you can also play a Trail of the Twister minigame and view the trailer in preparation for the full game's release next month.
