THE SHORT ANSWER

Cross-platform multiplayer is advertised on Steam and Xbox, and a FunPlus interview describes play across PC, consoles and mobile. Before choosing a platform or server, check whether you can join your friends and carry over an existing character.

Crossplay means playing together

Crossplay allows players on different kinds of devices to play together. Check the supported platforms, account requirements and server restrictions before arranging a session.

Mobile launches later than PC and consoles. Friends on mobile will need to wait for the mobile release to join.

Cross-save is a different feature

Cross-save or cross-progression means continuing your own progress on another platform. Check save-transfer support separately from crossplay before switching devices.

Xbox Play Anywhere covers the Xbox ecosystem. If you want to move a character between Steam and PlayStation, check the current account-linking and save-transfer instructions first.
