Publishing giant Activision Blizzard has reported that the recently-launched Call of Duty Modern Warfare is the biggest release on PC for the franchise to date.

The firm says overall the game brought in over $600m in shipments in its first three days, more than double the opening of recent cinematic release Joker and that Modern Warfare is the biggest premium game of the year so far.

“Call of Duty is once again the top selling new premium game of the year, proving the enduring nature of the franchise across console, PC, mobile, and esports,” the company's beloved CEO Robert Kotick said.

“In its first three days of release, Call of Duty: Modern Warfare more than doubled the box office opening of Joker.”

Activision president Rob Kostich added: “Through the first three days, Modern Warfare has more total players and total hours played than any Call of Duty opening release in the last six years. More importantly, our players are having a great time playing. Congratulations to Infinity Ward and all our teams involved on an incredible game and its spectacular launch. We also want to thank the community for your incredible support. The launch of Modern Warfare is only the start. There’s much more to come.”
