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. When a player(even the neutral player) has more delegates in a party than any other player, that player takes over the party leader seat for that party, and when a party has more delegates than any other party, it becomes dominant. The dominant party will become ruling during the next generation, imposing its one-time bonus, its ongoing policy, and granting chairmanship for its party leader, awarding that player 1 terraform rating.
