Bizarrely the official EA Star Wars twitter account has said that Xbox One and PS4 versions of Battlefront will use the systems built-in party system for "in-game chat"
rather than an integrated game communication system.
Meanwhile word has also been sent out by DICE for PC users to "choose your favorite third-party software to communicate with friends on PC."
It’s a strange choice not to include in game software for this, but I guess the framework is already there and massively underused so it should work fine.
The only thing it will lack is talking to the randoms that are not in your party. It takes some of the "social" away.
