Secret Operation (2019)

Misión secreta (Secret Mission) is a semi-cooperative card game with one or more hidden traitors.
Players play the role of engineers trying to build a state-of-the-art superrobot which is divided in 4 parts (card boards). Players add the pieces necessary to build each part, adding cards face down to the boards.

Every time the number of added cards equals the number of needed items, the players flip the cards and check if the added items match exactly the ones needed. If so, the task is completed, if not, they must build that part again from zero.

The goal of the game is to build the complete robot before the deck ends. If players fail to do so, the traitors win.

You depend on each other to fulfill the mission, but you’ll need to unmask the traitors that hide among you before it is too late.
