Something is wrong. Nobel Award-winning scientists and their revolutionary discoveries have vanished. This ripple in reality is a devastating loss for humanity, and it must be restored. Who has tampered with the past and disrupted the future? Only time will tell…

The city of Arkham is caught in a dark plot that spans across decades! From the quiet days of Arkham’s past to the bustling days of its future, you and your fellow investigators will chase the culprits of this chronological caper before they undo sixty years of important scientific discoveries. Will you find and rescue the missing scientists from their captivity in the twisted realm of Tindalos? Or will your travels through time cause unintended consequences for the past, present, and future?
