In only one short month, players spent over 500 million hours in Overwatch.

The period tracked starts with Overwatch‘s release date on May 24th, and goes until the end of Activision Blizzard’s second financial quarter on June 30th. In that amount of time, over 15 million players joined the game, making Overwatch the fastest-selling PC game in both China and beating out League of Legends‘ popularity in Korean gaming cafes.

“With Overwatch‘s incredibly successful launch, Call of Duty‘s record first half performance, and Candy Crush‘s continued growth as key drivers of our overall performance, we delivered a record Q2,” announced Activision Blizzard’s CEO Bobby Kotick. “The lynchpin of our current success and our future growth is our talent. Our teams have the unique combination of passion, entrepreneurial spirit and inspired creativity. The success of Overwatch, our newest franchise, is a testament to this talent.”

The combined profits from Overwatch, the Whispers of the Old Gods expansion in Hearthstone, and pre-purchases of the next World of Warcraft expansion, Legion, combined to make Q2 2016 Blizzard’s largest revenue quarter ever. Overall, Blizzard is up 29 percent quarter-over-quarter and 13 percent year-over-year.

Current profits from Overwatch‘s Summer Games event will count towards the next quarter, Q3.
