How to enable Apex Legends crossplay
Crossplay is enabled by default in Apex Legends, so you won’t need to worry about fiddling with settings to play with friends online. However, Apex Legends crossplay will only kick in when you’re playing with a friend on a different platform. In other words, if you’re flying solo and you’re on PC, you’ll only be matched with players on PC to keep things fair.
I have played with friends all three of us PC players and we do play vs console players when you see the champ sqd listed you can see PC tower, PS/Xbox controller and then the PC tower again . From what I can tell that's two PC players and a console player. Same happens when I am Flying solo.
