## Description
Terraforming Mars: Big Box Promo Pack is a bundle of 21 project cards and two corporations that you can add to your base game to supercharge the experience. The idea is simple: each new card brings fresh strategies, from cutting‑edge tech like the "Asteroid Deflection System" to social concepts like "Diversity Support." The corporations, Pharmacy Union and AstroDrill, give players distinct starting advantages, reinforcing the Variable Player Powers mechanic—each player has a unique playstyle that shines. If you like careful hand management, Open Drafting and Hand Management come into play, letting you choose project cards strategically. It also includes replacement cards that add new terrain tiles to the board—like the "Great Dam"—but remember: they only work if you already have the corresponding tiles in your Big Box. The pack doesn’t include those tiles, so don’t swap them out for existing cards without first ensuring your board is complete. In terms of time and complexity, the expansion keeps the base game’s standard: 120 minutes, 1‑5 players, and a strategy level from medium to advanced. If you already own Terraforming Mars and want something that boosts replayability without changing the core, this promo is what you need. The visual design stays true to the original, with futuristic Mars illustrations and colorful cards that make reading during the planning phase easy. In short, it’s a valuable bonus for anyone who loves building planetary empires and wants more card and corporation combinations.
