Terraforming Mars: Ares Expedition - Crisis

Play it solo, or band together with up to three friends to work together to save Martian society after a catastrophic asteroid collision has taken out nearly all of your infrastructure.

In Crisis Mode, the planet is already terraformed, but ongoing fallout from the impact is dropping temperatures, de-oxygenating the planet, and freezing over oceans,and there’s no time to evacuate the entire global population.

You must work fast, completing projects to counteract the ongoing crises and re-terraforming the planet before it becomes unihabitable… with billions of people still on it.
