Battlefield 1 is a game that has been released for both PlayStation 4 and Xbox One. However, it is not clear if the game is cross-platform. This question was asked by a user on the Battlefield 1 subreddit, and the answer given was that it is not currently possible to play the game on both platforms. This could be because of some unspecified technical issues, or because of how Battlefield 1 works with other games. It is also possible that this decision was made in order to keep things as close to vanilla Battlefield as possible.
