While doing prep for an upcoming radio segment; I contacted our rep at Activision and had confirmed that the upcoming Multiplayer Betas for Call of Duty: Black Ops Cold War will have Cross Play Enabled.
This is great news for gamers as since it was introduced in Call of Duty: Modern Warfare has jump started the online community for the game as players are no longer limited to playing only with those on a similar platform.
While the dates of the Beta are varied by platform; there will be opportunities for all formats to play with one another.
Starting on October 8th for PS4 players and October 15th for Xbox and PC players.
