With Chrononauts: Missing Artifacts, you can add six new mission cards to either Chrononauts or Early American Chrononauts — or both! These new missions will send you through time in search of missing treasures like one of the lost Fabergé Eggs, D.B. Cooper's suitcase full of money, a gemstone from Mars, and even the Holy Grail itself. (But make sure you choose the right one!) Or you might need to find a fully functional Antikythera Mechanism, a papyrus containing the secret to how the Great Pyramid was built, or a golden statue of Throk-Trak (hero of the cockroach revolution which happens 83 million years after WW3). The 18-card Chrononauts: Missing Artifacts expansion also includes a couple of powerful new gadgets: the Reality Shifter and the Temporal Stabilizer.
