Indie Game Studios’ Stronghold Games previewed the next expansion for its popular territory building series Terraforming Mars at the GAMA Trade Show. Terraforming Mars: Turmoil will release later this year. As the Twitter photo shows, the expansion will be on Kickstarter this spring.

Though not many details were available, the fifth expansion to Terraforming Mars takes players back to the red planet, to enter the struggle for control of human society on the dangerous world. New corporations will enter the playing field, as well as new projects, and a new card type – Global Events.

The last expansion, Colonies, sent players deeper into the solar system to gather resources and income (see “'Terraforming Mars: Colonies'”).

Stronghold Games merged with Indie Boards & Cards to form Indie Game Studios last year (see “Stronghold Games and Indie Boards & Cards Merge”).
