God of War has won critical acclaim from pretty much everyone, and now it is a massive commercial success as well. Publisher Sony Interactive Entertainment sold more than 3.1 million units of the franchise revival worldwide within its first three days of release, making it the fastest-selling PlayStation 4 exclusive yet, the company announced today.

Sony launched God of War on Friday, April 20, and the sales figures the company gave today are for the game’s opening weekend, April 20-22.

“I would like to personally thank the millions of fans around the world who decided to embark on Kratos’ latest adventure with us,” said Shannon Studstill, studio head at God of War developer Sony Santa Monica, in a statement on the PlayStation Blog. “Your support is truly inspiring, and it’s a reason why we push ourselves every day to go beyond the boundaries of play.”

God of War’s initial sales numbers are impressive on their own, but even more so in the context of Sony’s other high-profile PS4 exclusives.

Naughty Dog’s Uncharted 4: A Thief’s End, which was released in May 2016, was the previous record-holder for fastest-selling first-party exclusive (in North America, that is). Nathan Drake’s last excursion racked up sales of 2.7 million units worldwide, but in its first seven days of release. Last year’s Horizon Zero Dawn was the biggest debut in the history of Guerrilla Games, with more than 2.6 million copies sold during its first two weeks in stores.

This year’s God of War game is the first new entry in the long-running franchise since 2013’s God of War: Ascension. It brings Kratos out of ancient Greece to a new setting with its own mythology — Scandinavia and the Norse gods — and introduces his young son, Atreus, who accompanies him on an emotional journey.
