Hello All!
This new update introduces the crossplay feature between Steam and the Epic Games Store. If you’re playing on Steam and want to play or connect with players/friends on the Epic Games Store (EGS) to match your global achievements, you'll need to have an EGS account. If you don’t accept, you can only play on Steam and the crossplay will not be enabled. Simply press the "x" in the upper right-hand corner to opt-out and continue playing on Steam. If you accept, a web page will open in your browser asking you to log in to (or create) an EGS account.
