i'm not actually too sure if this game has crossplay or not. i heard that only some platforms work with others. but if there isnt crossplay, then it should be added. i tried joining my friend who plays on playstation using my xbox via the lobby code feature but it just kept saying "game not found", so im assuming xbox and playstation aren't one of the compatible pairs. a game-built friend system would go great with this feature, as you wouldnt have to use lobby codes every time you want to play with someone else, but rather just invite or join them with a friend system.

Crossplay between platforms will come somewhere around autumn and winter (hopefully)
