Yesterday, Sony surprised players all over the world by finally opening up to cross-platform play with other consoles. The first game supporting it will be Fortnite, but it’s already been confirmed that other third-party titles will be able to do the same in the future. Sadly, it seems like Fallout 76 won’t be among them.

Following yesterday’s Sony announcement, Bethesda’s Pete Hines commented on Twitter about the possible cross-platform play support for Fallout 76. Unfortunately, it’s not on Bethesda’s radar at the moment, as the team is focused on the game’s soon to begin beta and launch. He also added that he has no idea if cross-platform play is ever going to be supported.
