These promos are the digital version of the promos we sent to our Kickstarter backers during the Frontiers Kickstarter campaign. There are 17 new cards in Frontiers Promos.  Each faction gets a base with a double-ally ability, a powerful ship with an ally scrap-from-play ability, and a new ship type that introduces the “Docking” mechanic. It also includes the first 9-cost ship, “The Colossus”.
