Following a year of patchy DLC releases, Civilization VI is preparing to deliver its first full expansion, entitled Rise and Fall. The hefty add-on will introduce a wide variety of new features and content, including nine new leaders representing eight civilizations.

Previously, Civilization VI developer Firaxis revealed Korea under Queen Seondeok, and the Netherlands under Queen Wilhelmina will be part of the Rise and Fall expansion, and now they’ve unveiled a classic – Mongolia as led by the infamous Genghis Khan. The Mongols under Genghis Khan have been part of every Civilization game to date, because of course they have.
