Smash Up: Cease and Desist can be played on its own as a two-player game or combined with other Smash Up titles to allow for up to four players to compete for control of bases at the same time. Cease and Desist includes four factions — Astroknights, Changerbots, Star Roamers, and Ignobles — with 22 cards for each faction. To play, you shuffle together any two factions, whether from this set or any other Smash Up title, then start playing. Smash Up: What Were We Thinking? returns to the wild randomness of the early days of Smash Up. By combining this expansion with your Smash Up sets, will you take Zombie Rock Stars against Explorer Dinosaurs? What about Time Travelling Grannies versus Teddy Bear Vampires? It’s all possible now! All your dreams can finally come true!
