Todd Howard, the Bethesda Game Studios director and creative leader behind the forthcoming Fallout 76, bluntly called out Sony when a German publication asked why that game wouldn’t support cross platform play.

“You cannot do cross-play in 76,” Howard said, according to GameStar.de (via CNET). “We’d really love that but right now we can’t. Sony is not as helpful as everyone would like.”
