It's no secret that Battlefield 6 will be getting a battle royale mode: Of course it will, obviously, but also EA has already explicitly said it will. What it hasn't said is when that mode will go live, but now it has--and it's coming tomorrow, October 28, the same day as the launch of Battlefield 6 season 1.
Specifically, according to today's surprise post on X, Redsec will arrive at 8 am PT/11 am ET/4 pm UK.
