Diablo 3 publisher Activision Blizzard has sold more than 30 million copies of the action role-playing game, the company announced today.

The figure represents worldwide sales to customers of Diablo 3 since the game's debut in May 2012, said Activision in the earnings report for the second quarter of its 2015 fiscal year. Activision's second quarter ended June 30, meaning Diablo 3 reached the 30 million sales mark in just over three years.

It's unclear if the sales numbers apply just for the stand-alone game, or if they also include copies of the expansion Diablo 3: Reaper of Souls, which launched in March 2014. We've reached out to Blizzard for clarification, and will update this article with any information we receive.

Diablo 3 was already the best-selling PC game of all time, having earned that title a year ago when lifetime sales of the game and Reaper of Souls topped 20 million copies. Blizzard launched Reaper of Souls in China in April. For more on Diablo 3, check out our Overview of the game's Ultimate Evil Edition below.
