Activision sold more than $1 billion of Call of Duty: Ghosts into retail stores worldwide as of day one, the publisher has announced.

Call of Duty: Ghosts launched worldwide on November 5.

"Call of Duty is by far the largest console franchise of this generation," said Bobby Kotick, CEO of Activision Blizzard. "More people have played Call of Duty this year than ever before, logging four billion hours of gameplay. And in the last 12 months, Call of Duty: Black Ops II, including its digital content, generated more revenues than any other console game ever has in a single year. Although it is too early to assess sell-through for Call of Duty: Ghosts, it's launching at a time when the franchise has never been more popular."

Activision says that millions of people are already playing Ghosts online, with the game already moving to the No.1 spot in the Xbox Live chart.

Furthermore, Activision confirmed that on the Xbox 360 average player sessions for Ghosts have been longer than either Black Ops II or Call of Duty: Modern Warfare 3, during the same time period.

"Ghosts is an amazing game which ushers in the next generation of Call of Duty. The team at Infinity Ward has delivered yet another epic thrill ride in the campaign, and what I think is our best multiplayer game yet," said Eric Hirshberg, CEO of Activision Publishing.

He added: "This is the must have launch title for the next generation of consoles, and we expect Call of Duty: Ghosts to be the most successful launch title for the Xbox One and PS4 by a wide margin. In fact, according to GameStop, Call of Duty: Ghosts is their most pre-reserved next gen title."
