If you thought Terraforming Mars had already said it all, get ready, because the sixth expansion, Prelude 2, has arrived to shake things up even more! This gem focuses on adding that extra spice with effects that interact with other expansions, bringing Prelude cards that offer ongoing abilities and special actions right from the start. And it doesn't stop there: more project cards to boost your tableau and five new corporations that promise to change how you play. Fans of the Venus, Colonies, and Turmoil expansions will be thrilled, as many cards were designed with them in mind. But relax, if you don't have those additions yet, the five corporations and fifteen Prelude cards work perfectly with the base game. Oh, and if you snagged the Kickstarter edition, there's an extra promo pack with more cards to make everything even more packed. Prelude 2 is for those who want more depth and new strategies on their journey to make Mars a habitable place. It's more Terraforming Mars, with more options and more fun!
