Throughout the components of the MIND MGMT game, there are 9 hidden codes. When you enter these codes into the website FluxSafeHouse.com, they give you a brand new card that you can print out and add to your game. This Secret Mission expansion provides all 9 of the hidden cards, professionally printed.

Each card will come sealed in an envelope so you can choose to either open them all up, or search for the hidden codes yourself. When you find a code and enter it into the website, you will be instructed to open a specific envelope.
