If you thought the challenge of terraforming Mars was just about oxygen and temperature, get ready for some political chaos! Turmoil is the fifth expansion for Terraforming Mars, and it introduces something the base game lacks: the human factor (and all its drama). Now, besides building cities and forests, you'll have to navigate the Terraforming Committee, a political arena where controlling different parties can completely shift your economic trajectory.

The standout feature is the Global Events cards. Forget the usual predictability; now, dust storms, social riots, or sudden spikes in alloy demand can pop up and disrupt your plans for generations to come. To navigate this uncertainty, you'll need delegates. You can invest to gain influence within parties to ensure the dominant policy favors you, or you can use your political influence to mitigate the negative effects of global events.

The expansion introduces an 'area majority' mechanic applied to politics: whoever controls the most dominant party dictates the rules for the next generation, setting bonuses and policies that affect everyone. It's a much more aggressive and reactive layer of strategy. You can play a moderate, economy-focused game, or you can be the agitator using global events to topple the leader. With new corporations and projects, Turmoil turns the game into a true simulator of human society on a hostile planet. It's perfect for players who have mastered the base game and want to feel the weight of social and political decisions in their hands!
