For a brief moment, cross-play between PS4 and Xbox One was enabled in Fortnite over the weekend. Developer Epic claims this was an error.
A Reddit user noticed during their PS4 session that they were playing with someone that had a space in their name – something PSN usernames don’t allow. At first, they thought this could have been a PC user (as cross-play between PS4 and PC is supported). Further investigation from NeoGAF found that they were in fact an Xbox One user.
Similar events were reported, including one who claimed to be playing with their child across both consoles.
The feature has since been removed. "We had a configuration issue and it has now been corrected,” Epic shared in a brief statement to GameSpot.
Sony has seemed reluctant to allow cross-play between the PS4 and Xbox One; something which Microsoft is pushing for with Minecraft. Rocket League will allow cross-play between Xbox One, Switch, and PC versions.
