A few news items I wanted to call to your attention:
Treyarch is bringing back community-favorite maps from Black Ops Multiplayer: Jungle, Slums, Summit, and Firing Range. All four maps will be playable for all Black Ops 4 fans on all platforms on October 12
The iconic and fan-favorite map Nuketown will also be available for free to all Black Ops 4 players in November
Also, please note that fans will also be able to play Call of Duty: Black Ops 4 multiplayer at the Call of Duty World League event in Anaheim, CA the weekend after E3 – http://www.majorleaguegaming.com/cwlanaheim2018.
