Is Dying Light 2 Cross-Platform/Crossplay?

No, Dying Light 2 does not support full crossplay between PC, PlayStation, and Xbox. 

The 2022 game unfortunately doesn’t support crossplay between platforms, but does allow cross-generation play. That means that Dying Light 2 players on PS5 can play with friends on PS4, Xbox One with Xbox Series X/S, and Steam with Epic Games Store players.
