Call of Duty: Black Ops Cold War will begin integrating with Warzone in December, Activision has said.
Speaking during an investor call last night, Activision's chief operating officer Daniel Alegre said this integration kicks off with Black Ops Cold War's first season. Black Ops Cold War comes out on 13th November.
It is unclear exactly how Black Ops Cold War will work within Warzone, but we do know all new Black Ops Cold War weapons and operators you unlock will be usable in both Black Ops (as you'd expect) and Warzone. Content within the Black Ops battle pass, as well as new Black Ops store content, will also work across Black Ops and Warzone.
