In a series of missions, players terraform new planets and discover new cards and mechanics. Winning a mission makes you governor of that planet and earns you extra points for the final mission where the overall winner will be decided.

Based on the familiar mechanics of Terraforming Mars, Legacy of Mars adds mechanics such as melting glaciers, worker resources, population, unlocking powerful innovation cards, and developing your corporation over time with more and more (prelude-like) development cards.

Each mission is set on a new planet, starting with a new side of Mars (needing 15 ocean tiles). New parameters, new mechanics, and new card pools mean that this is essentially several games in one box.

This campaign is fully replayable and it is about what we take with us from having terraformed Mars - the Legacy of Mars.
