The Subterfuge expansion for Fantastic Factories brings exciting new elements. It adds fresh blueprints and offers direct player interaction. You can hire contractors to steal resources, cards, or dice from your opponents. Also, it introduces a sabotage mechanic to disable your rivals' factories, making the game more thrilling and strategic.

To use this expansion, simply add the new blueprints to your existing Fantastic Factories game. When it's your turn, you can choose to hire contractors. Just decide which resources, cards, or dice you want them to steal from your opponents. For the sabotage mechanic, when the right moment comes, use it to stop your opponent's factories from working. When storing the game, keep it in a dry place to prevent damage to the cards and components. Avoid bending the cards and make sure to put all the pieces back in the box after each play to keep everything organized.
