If you're the type who is never satisfied with the number of cards in your hand and always wants another option to boost your strategy on Mars, get your rocket ready! We are talking about the X24 promo card, a relic from the WSBG 2024 that is now part of the massive FryxGames 2025 Season Promo Pack. But watch out for the clock: until March 2026, you can still hunt for this card separately, but after that, it will only be available as part of the official season pack. It's the kind of item any Terraforming Mars collector will want on their shelf to complete their arsenal.

But what does this card actually do in practice? It is a Building tag card that requires an initial investment of 5 M€ and, of course, you must have at least one city already established on the planet to activate it. The effect is a classic resource trade-off that can shift the course of your economy: you sacrifice one level of your energy production to gain a massive 4-level jump in your M€ production. It's the kind of card that turns a heavy infrastructure project into a powerful financial engine, ideal for those who already have excess energy production and need cash to fund their next mega-constructions.

Keep in mind that, like any expansion or promo card, it adds an extra layer of possibilities to your board. It doesn't change the fundamental rules of the game, but it offers an alternative route for those looking to focus on aggressive economic growth. If you've already mastered the base game and feel like your matches need an extra kick of spice, this card is the ingredient missing to make your resource management even more dynamic and strategic.
