Publishing giant Activision Blizzard has reported a slight decline in its monthly active user (MAU) figures for the three months ending June 30th, 2019.

For the last financial quarter, the company says it had 327m MAUs, a decline of five per cent on the 345m it reported for the three months ending March 31st, 2019. It's also a decline of seven per cent year-on-year compared to the 352m figure it revealed for the same quarter 12 months ago.

That's not exactly a like-for-like comparison, however, given that Activision Blizzard could still count users from Destiny 2 during the three months ending June 30th, 2018. Developer Bungie has since acquired the publishing rights from Activision Blizzard, though prior to this the game boasted around six million monthly active users.

Of the 327m figure, Activision boasts 37m - a decline of four million since March due to a dip in Call of Duty users - while Blizzard's MAU figures stayed steady quarter-for-quarter at 32m. Unsurprisingly, mobile firm King was behind the majority of Activision Blizzard's monthly active users with a whopping 258m, itself a four per cent decline year-on-year. 

The publishing giant also claimed that both engagement and MAU metrics grew for Call of Duty grew year-on-year, with users playing 2018's Black Ops 4 for 50 per cent more hours than the previous year's WWII. Furthermore, Activision Blizzard boasts that net bookings - spending on in-game items and so on - for Black Ops 4 are ahead of WWII at the same life-to-date.
