Call of Duty: Black Ops IIII debuts on October 12.

Call of Duty: Black Ops 4 on PC will use Blizzard’s Battle.net

Call of Duty: Black Ops 4 will use Blizzard Entertainment’s Battle.net online gaming service. The switch from Activision’s own service to Blizzard shows increasing cooperation between the Activision and Blizzard sister companies, which the parent Activision Blizzard owns.

The move by Treyarch, the Activision-owned studio developing this year’s Call of Duty game, reflects the growing importance of the PC as a gaming platform, said studio head Mark Lamia in a press briefing. Lamia said that development studio Beenox has a dedicated team “working to build the most robust and customizable PC experience that you have ever seen.”
