Turmoil, the fifth expansion to Terraforming Mars, takes players back to Mars, and the struggle for control and progress of human society on a big and dangerous planet.
The expansion includes new corporations, new projects, and a new type of cards ? Global Events, from dust storms to riots to rising alloy demand ? that give you something to plan for 3 generations in advance.
At the heart of this is the political arena of the Terraforming Committee. A new action allows players to add delegates to different parties, the first delegate each generation being free, and additional ones costing 5 MC. Neutral delegates are added by the global events, representing the wishes and trends of society.
