Overwatch has earned Blizzard more than a billion US dollars in less than a year, parent company Activision Blizzard announced in an earnings call today.

That figure includes revenue from sales of the game, as well as cash from microtransactions like loot boxes.

The game has more than 30 million registered players, and it continues to be Blizzard’s fastest growing new franchise, Activision Blizzard said.

Overwatch is the eighth Activision Blizzard game to cross the billion-dollar milestone, putting it in with the likes of Call of Duty, Guitar Hero and World of Warcraft.

Elsewhere in the call, Blizzard studio head studio head Mike Morhaime said the competitive Overwatch League is on track to kick off later this year.

Blizzard has 41 million monthly active users across all games – up 58 percent year-over-year.

CEO Bobby Kotick noted that Activision Blizzard beat its first quarter forecasts, reaching "record revenues, earnings per share and cash flow" in the process.
