But that's only a fraction of what you'll find in this expansion! Adding even more flavor to your chosen species, a wealth of unique leader cards arrive to support every faction in the game, giving you powers to unlock during the game. Lumbering mechs stomp onto the battlefield as powerful new ground forces with unique special abilities for every faction. As you venture into the unknown regions of space, brand-new exploration decks seed new planets and the void of space with new discoveries, including fragments you can combine to create awe-inspiring relics. On top of this, Prophecy of Kings includes new action cards, agenda cards, objectives, technologies, promissory notes, legendary planets, and more.
