Treyarch have just announced on Twitter that the Black Ops 3 multiplayer beta will officially start on Wednesday, August 19th! That’s in just 6 weeks time and is an ideal time for the devs to listen to the community’s feedback.
As per the new exclusivity agreement, the beta will start on PlayStation 4 before it arrives on Xbox One and PC and those who pre-order the game will be guaranteed access. There are no plans for it to come to last-gen platforms.
We're excited to announce that the #BlackOps3 Multiplayer Beta will begin on 8/19 starting on PS4. More information coming soon!
