We've already known that this year's new Call of Duty game will indeed be Call of Duty: Black Ops 4, as many had speculated, but up until now, Activision has only shared brief tidbits about the anticipated shooter. The publisher will formally pull back the curtain on Black Ops 4 during a special event later this month, and now we have more details on when that will occur.

Activision has begun sending out invitations to its Call of Duty: Black Ops 4 Community Reveal Event, which takes place on May 17. The invites don't divulge any information on exactly what the publisher will talk about during the event, but it does reveal that the keynote conference begins at 10 AM PT / 1 PM ET.
