The seventh World of Warcraft expansion, Battle for Azeroth, has become the fastest selling expansion in the franchises history, Activision Blizzard has announced.

　　More than 3.4 million copies were sold on its launch day earlier this month, thereby beating the sales records set by the previous World of Warcraft expansions, including the Legion expansion from 2016.

　　Battle for Azeroth is a definitive chapter in the Horde and Alliance conflict at the heart of Warcraft, and it’s been thrilling to see players representing their factions in record numbers and embarking on their war campaigns—not to mention joining in ourselves,” said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. “But the launch is just the beginning of this conflict. More epic content is coming to World of Warcraft in the weeks ahead, and we can’t wait for players to experience the full story as it unfolds over the course of the expansion.”

　　Battle for Azeroth was released earlier this month on August 14.

　　Today’s launch signals the start of a new era of all-out warfare between the Alliance and the Horde, as players around the globe set out on a vital mission to ensure that Azeroth’s future belongs to their faction. Defenders of the Alliance are called to the kingdom of Kul Tiras, ancestral home of Jaina Proudmoore, to enlist the aid of their legendary navy, while champions of the Horde must seek allies in the distant empire of Zandalar, home of the ancient Zandalari trolls.

　　As part of the campaign ahead, heroes will clash for critical resources in myriad Island Expeditions; draw upon the strength of Azerite, lifeblood of the planet, to unlock new powers using the Heart of Azeroth artifact; prepare for a massive confrontation on the Warfront of Stromgarde; recruit new Allied Races to bolster their faction’s cause; and much more.

　　“Battle for Azeroth builds upon nearly 25 years of faction rivalry, history, and pride to challenge World of Warcraft players with the question of what it truly means to be a member of the Alliance or the Horde,” Morhaime said. “This expansion is loaded with new content and features that draw upon that core conflict, but today’s launch is just the beginning—we’re excited for players to experience everything we have planned as the Battle for Azeroth unfolds.”
