Is there crossplay in Call of Duty: Warzone?

Yes, Call of Duty: Warzone has crossplay, which allows players from different platforms: PC, Xbox, and PlayStation. Imagine playing on PC, while your friend plays on Xbox and another friend on PS. You can all play Warzone together in the same match. Keep in mind that assembling a team from different platforms may pose challenges, as aiming with a gamepad is harder than with a computer mouse.
