Warhammer: Invasion is a Living Card Game (LCG) designed by Eric M. Lang and produced by Fantasy Flight Games in 2009, set in the Warhammer Fantasy universe. Like Fantasy Flight's other LCGs, Invasion is sold as a core set, which can be played on its own, or built upon with expansion packs. Each pack has a fixed set of 3 copies each of 20 cards. There are six factions in Invasion: Dwarves, Empire, Orcs, Chaos, High Elves, and Dark Elves. The first four have decks in the core set, while the elves' decks are available in the Assault on Ulthuan expansion.
