Meet the makerThe mission: Your story in Pasadena
A large red button sits on a desk. Always curious, you press it. You look at the desk and see a note.
“Tolman, this isn’t something I’m proud of but it’s the only way to defeat the Germans at their own game. This button releases a nuclear bomb. I’ve hidden eight devices around town to disarm it.”
With the note still in your hand, you race out of the room. You must find clues to stop this before it’s too late.
