The On Mars Upgrade Pack delivers a bundle of extras that lands straight onto your table, like a video‑game DLC. Born from a Kickstarter crowdfunding campaign, it lets you add more contract cards, private goals, and even an extra blueprint board. Instead of sticking with the basic set, the pack offers 12 new contract cards that broaden alliance and negotiation options, plus 6 private goal cards that add a strategic layer of “what I want and what others don’t know.” The extra blueprint board helps keep your building pieces organized, making it easier to see where each module will go. For players familiar with the base game, the pack works as a supplement that keeps the hand‑management and point‑to‑point movement mechanics intact while adding more contract and goal variety. If you enjoy exploring new scenarios and want to boost replayability, this upgrade is a great way to deepen the Mars universe. On the flip side, newcomers may find the extra components raise the complexity and learning curve. In short, the On Mars Upgrade Pack is a lightweight expansion that offers more options without radically changing the original experience, ideal for those who already own the game and seek more challenges.
