Carbon Nanosystems (Promo Card X52) is a specialized active card in Terraforming Mars, featuring Science and Building tags. Its primary effect triggers on playing any science tag—including itself—adding a graphene resource directly to the card. Secondarily, these graphenes serve as a valuable currency equivalent, worth 4 M€ apiece specifically when playing space or city tags. This promo was bundled with the Prelude 2 Kickstarter but remains accessible in limited quantities through select board game conventions or directly from FryxGames, enabling players to integrate graphene production into science-heavy strategies while providing economic flexibility for space and city developments.
