Publishing giant Blizzard has claimed that its recently-released World of Warcraft expansion Shadowlands had the biggest Day One sales of any PC game ever.

In a release, the firm said that the title shifted more than 3.7m units globally on its first day in the wild. The previous record-holder was Blizzard's own Diablo III – which launched back in 2012 – and sold 3.5m copies in its first 24 hours.

Furthermore, the company has claimed that in the build-up to launch, more people were playing its game than ahead of any other expansion in the last ten years.

“It’s been a huge thrill to enter this whole-new dimension of the Warcraft universe together with millions of players around the world,” Blizzard president J. Allen Brack (pictured) said.

“It’s been equally rewarding to see players enjoying all of the new features and content in Shadowlands—whether they’re exploring new aspects of their characters with the Covenants or setting foot in WoW for the first time with the new-player experience in Exile’s Reach—and there’s much more to come.”

Shadowlands was released on November 23rd following a delay from its original release date in October.
