Warhammer 40,000: Conquest was a Living Card Game (LCG) produced by Fantasy Flight Games, set in Games Workshop's Warhammer 40,000 universe. It was announced in March 2014 and was released October 3, 2014. The game featured two players competing to win a series of battles on a different planets while simultaneously securing the resources of other planets that will have battles on subsequent turns. Fans of the game praised the strategic element of having multiple distinct battle fields as a feature that distinguished it from other card games. On September 9, 2016, Games Workshop announced that Conquest would be discontinued in February 2017, as a result of Games Workshop's failure to renew Fantasy Flight Games' contract because of a conflict between Games Workshop and Fantasy Flight Games' parent company, Asmodee. The game still has a small community of players who play with the cards that were printed before the game's discontinuation in 2017, and some fans have made unofficial expansions to expand the small card pool.

Fantasy Flight Games (FFG) is a game developer based in Roseville, Minnesota, United States, that creates and publishes role-playing, board, card, and dice games. As of 2014, it is a division of Asmodee North America.
