Activision announced today that the second Call of Duty: Black Ops 4 public beta test will begin on September 10. On the PlayStation 4, that is—the rest of us will have to wait a little longer.

Assuming the schedule follows the same pattern as the first public beta, which debuted on August 3 for PS4 and August 10 for PC and Xbox One, we can expect it to come to PC the following weekend—so, September 17. An Activision rep said that date hasn't been confirmed yet, but I'll update if and when it is.
