The first session of the private multiplayer beta for Call of Duty: Black Ops 4 takes place this weekend for some players. Ahead of the test, Activision and developer Treyarch have shared an intense new trailer showcasing the various Specialists, maps, weapons, and other content that will be available to try out during the beta.

The private multiplayer beta is only available to those who pre-order Call of Duty: Black Ops 4--although Xfinity customers will also be able to participate, even without reserving the title. The first session kicks off exclusively on PlayStation 4 at 10 AM PT / 1 PM ET on Friday, August 3, and runs until the same times on Monday, August 6. A second session will be held for all platforms--PS4, Xbox One, and PC--the following weekend from August 10-13. You can see the full schedule below.
