Terraforming Mars - Ares-expedition: Krisen

Ares-Expedition: Krisen is a completely new way to play that utilizes the mechanics from Terraforming Mars: Ares-Expedition for a new challenge. It can be played solo or with up to 3 friends to save the Martian community after a catastrophic asteroid impact that has nearly destroyed the entire infrastructure. In the Krisen mode, players start on a planet already terraformed, but the ongoing effects of the impact cause temperatures and oxygen levels to drop and the oceans to freeze. There is no time to evacuate the entire population. You must act quickly and complete projects to counter the ongoing crises and terraform the planet again before it becomes uninhabitable... with still billions of people on it.
