The ongoing saga between Sony and Microsoft’s cross-play battles has taken another twist today. Epic Games originally announced cross-play and cross-progression earlier this week between the PlayStation 4, PC, Mac, iOS, and eventually the Android versions of the game. While Microsoft’s Xbox One was missing from the list, the company revealed last night that it will support cross-play on Fortnite for Xbox and that it will be available in the future.

Unfortunately, that cross-play won’t happen between PlayStation 4 and Xbox One players. Epic Games’ Nick Chester revealed on Twitter today that Xbox One players will only be able to play Fortnite with PC, Mac, and mobile players, and PS4 players will also be limited to play against PC, Mac, and mobile. It’s now clear that PS4 vs. Xbox One Fortnite cross-play will not be supported, despite there being no technical reason it can’t work. Epic Games briefly enabled the cross-play last year, and PS4 and Xbox One gamers were able to play against each other due to a “configuration issue.”
