Last month at E3, Bethesda unveiled a new Fallout game: Fallout 76, an online, multiplayer survival game. The game will be available on the Xbox One, Playstation 4, and PCs when it’s launched this November, but according to the game’s director, it won’t allow for cross-play, because of Sony.

Todd Howard told GameStar.de (via CNet) that “we would love to do [cross-play]” in Fallout 76, “but right now that’s not possible.” The reason, he says, is Sony, which is “not as helpful as everyone would like.”

Sony has already irritated fans by blocking cross-play on Fortnite between Playstation 4 and Nintendo Switch players, and during E3, issued a statement saying that “we’re always open to hearing what the PlayStation community is interested in to enhance their gaming experience,” and noted that it already allows cross-play between PC, Mac, iOS, and Android devices. After facing backlash from fans, Sony seemed to listen to the feedback it got, saying that it was “looking at a lot of the possibilities,” and that it was “confident we’ll get to a solution which will be understood and accepted by our gaming community.”
