The Asteroid Rights promo card arrived as a bonus in Spielbox 01/21 and offers a fresh way to handle asteroids in Terraforming Mars. At the start of the game you receive two asteroids directly on the card, giving you a small ready‑made stash. The card’s action gives you two choices: spend 1 M€ to add an asteroid to any other card in the game, or spend one of the asteroids on this card to raise your M€ production by one step or gain 2 titanium. This flexibility lets you tweak your economic or mining strategy on the fly. Need more money? Turn asteroids into M€ production; already have enough production? The titanium boost can speed up building projects. The card acts like a tiny resource bank you can manipulate anytime, fitting nicely with hand management, set collection, and variable player powers. Because it’s a promo, it’s limited (x34) and can be a collector’s item for fans of the series. While it doesn’t overhaul the core game, it adds an extra decision layer that can be decisive in tight matches, especially in solo play where every resource matters. In short, Asteroid Rights is a short, thematic add‑on that will please anyone already loving Terraforming Mars and looking for more resource‑management options.
