Nancy Drew: Trail of the Twister

Trail of the Twister is the 22nd installment in the Nancy Drew point-and-click adventure game series by Her Interactive. It is available for play on Microsoft Windows and Mac OS X platforms. It has an ESRB rating of E for moments of mild violence and comic mischief. Players take on the first-person view of fictional amateur sleuth Nancy Drew and must solve the mystery through interrogation of suspects, solving puzzles, and discovering clues. There are two levels of gameplay, Junior and Senior detective modes, each offering a different difficulty level of puzzles and hints, however neither of these changes affect its plot. It is loosely based on the book The Mystery in Tornado Alley (2000).

Plot
A series of equipment meltdowns have been plaguing a prominent Oklahoma storm research team. They are in the running to win a $100 million grant in the upcoming Green Skies storm competition, when disaster strikes and an intern becomes stranded directly in the path of a storm, leaving him with a broken leg. P.G. Krolmeister, the funder of the team, sends amateur detective Nancy Drew to join the team undercover as an intern to find out who has been sabotaging them. She had better keep her wits about her, as she not only has to uncover a saboteur, but battle some of the deadliest twisters in Oklahoma!
