About this game

Step into a controlled chain of influence and calculated pressure in The Cardfall: Ruin Protocol. You operate behind the surface, shaping public opinion across four distinct sectors over a fixed span of ten years. Every decision matters, as each year grants only two actions to shift the balance and move closer to total destabilization.

Actions are drawn and directed towards a chosen sector, altering its current state of public perception. Yet no change remains unchallenged. At the end of every year, each sector restores part of its own rating, resisting your efforts and forcing you to plan beyond immediate impact. Progress depends on understanding when to act and when to wait.

In The Cardfall: Ruin Protocol, collapse begins when a sector is driven into negative opinion. At that point, it enters ruin and stops recovering. However, destruction is not automatic. A precise follow-up action without modifiers must be applied while the rating remains below zero. If prepared correctly with a prior matching action, the final move delivers an additional drop, pushing even a neutral state into collapse.

Limitations define your strategy. Once a sector is ruined, it becomes untouchable, and no further actions can be applied. Only visible changes persist—replacing an action removes the previous effect entirely, requiring constant recalibration.

Victory in The Cardfall: Ruin Protocol demands the complete destruction of all four sectors before the ten-year cycle ends.
