It should have been simple -you were hired to steal six priceless exhibits from the museum then get out and get paid. But someone in your crew is a traitor! One of you has already stolen a target exhibit and replaced it with a fake- and they triggered security to boot. You need to get out before the guards find you and work out who betrayed you, what they stole and where they hid it. Cooperative gameplay. Dynamic Gameboard- Solve the Mystery.
