Terraforming Mars: Prelude Expansion
In Terraforming Mars: Prelude, you get to choose from Prelude cards that jumpstart the terraforming process, or boost your corporation engine. There are also 5 new corporations, and 7 project cards that thematically fit the early stages of terraforming. This is the third expansion to Terraforming Mars, and can be combined with any other expansion or variant.
This is not a stand-alone game. A copy of Terraforming Mars is required to play.
