## Description
The Carbon Nanosystems promo card is a small but powerful addition to Terraforming Mars, especially for fans of science and building strategies. Originally released in the Prelude 2 Kickstarter, this card is also available in limited quantities at conventions or directly from FryxGames. It features two neat abilities: whenever you play a science tag (including itself), you add a graphene resource here. Plus, when playing space or city tags, you can spend these graphenes as 4 M€ each. A perfect little boost for the base game without any fuss!
