As the mega corporations are getting ready to start the terraforming process, you now have the chance to make those early choices that will come to define your corporation and set the course for the future history of Mars – this is the prelude to your greatest endeavors!

Terraforming Mars: Prelude introduces the new Prelude cards. At the start of the game, each player chooses from Prelude cards that jumpstart the terraforming process or boost their corporation’s engine. This expansion also includes 5 new corporations and 7 new project cards that thematically fit the early stages of terraforming a new planet and can be added to the game even if you’re not using the Prelude cards; and a new solo mode where your goal is to get to 63 TR before time runs out instead of completing the global parameters.

Prelude is an expansion to Terraforming Mars, and can be combined with any other Terraforming Mars expansions or variants.
