Terraforming Mars: Turmoil – Politics Comes to Mars

Global events, political factions, and a Terraforming Committee that can help or destroy your strategy — the most divisive Terraforming Mars expansion.

Terraforming Mars: Turmoil is the fifth and most controversial expansion in the Terraforming Mars library. It introduces a Terraforming Committee — a political body representing five ideological factions vying for control of the Martian terraforming agenda. Every generation, the ruling party imposes policies that affect all players, and global events add unpredictable challenges that nobody can fully plan for.

The result is an expansion that the Terraforming Mars community is deeply divided on. Players who love political games and narrative chaos adore it. Players who prefer pure strategic control often find it frustrating. Understanding which type of player you are is the key to deciding whether Turmoil belongs in your collection.

Players who embrace Turmoil consistently describe sessions as the most dramatic and memorable Terraforming Mars experiences they've had — the political swings and global events create stories that pure engine-building never generates.

What Does Turmoil Add?

How Does It Change the Game?

Each generation ends with a political resolution phase. Delegates are counted, the leading party takes power, and their policy activates — providing benefits to players who supported them and potentially penalizing those who didn't. Then a global event card reveals a random challenge that all players must navigate.

This creates a second strategic layer on top of the existing engine-building. You're no longer just optimizing your corporation — you're also managing political influence, reading which factions your opponents are supporting, and deciding when the ruling party's policy is worth fighting for.

The global events are the most divisive element. They introduce genuine randomness that can swing the game significantly. Some players love the drama. Others find it undermines the careful planning that makes Terraforming Mars satisfying.
