Blackout’s beta kicked off a bit earlier on PS4, but that does mean there are plenty of videos and streams that you can plug into until it appears on PC. Since it’s a battle royale game and Call of Duty, there are quite a few of them

The PC beta starts on the 14th for pre-orders and the next day for everyone else.
