Terraforming Mars: Ares Expedition – Crisis^*

Players take on the role of companies, similar to the original Ares Expedition. They choose phases and play project cards as usual but must cooperate to keep Mars habitable after a natural disaster has plunged the planet into crisis. Each round introduces a new crisis card, requiring players to reach specific goals; failure to address a crisis lowers the Terraforming metrics crucial for Mars' habitability.
