50 Clues: No Sign of Life

From BoardGameGeek:

No Sign of Life is the first episode of the story-driven escape game trilogy, Sunshine Island. With trembling hands and tears in your eyes, you open the sealed cardboard box. ”Day 8,” as your sister called it. ”If you don't hear from me every week, then I'm in trouble.” She never revealed what her mission was, but she's a researcher specializing in biological warfare agents for the Armed Forces and the fear in her eyes was unmistakable. This time there was something out of the ordinary. What has happened and how can you help her? Go on a rescue mission in the role of Sigrid. 50 Clues is an award-winning immersive puzzle game that offers the experience of an escape room, but in a format that can be played at home. You combine objects, solve puzzles and decipher codes to complete the story. A smartphone or tablet keeps track of the solutions and provides multistep hints if the need arises. -description from the publisher
