Terraforming Mars: Turmoil is the 5th expansion to the smash hit game. In this new expansion, players are taken back to Mars and struggle for control of the Terraforming Council, the governing body on Mars. By having majorities in political parties on Mars, they can sway the progress of human society on the red planet. Controlling parties or being the head of the Terraforming Council itself will give you greater benefits (or less disadvantages) when Global Events occur on Mars. Terraforming Mars: Turmoil includes new corporations, new projects, and a new type of car.
