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.

In Turmoil, players can try to force their own agenda, or push it in a more moderate, economic way. They can play to mitigate the global events with influence, or adjust their play to better take advantage of them. And they can anticipate the competing players' agendas and try to benefit from them, or counteract them.

Turmoil is an expert expansion - be prepared to meet the full spectrum of human civilization in the era of terraforming Mars!
