Chat for the game is supported through the PDM party system. So right now you can only talk to people who are in that party. You cannot talk to anyone in the game that is not in your party.
I haven't played around with it enough but there are 2 settings when setting up a party chat;Friends of Friends:
Friends of friends of the owner can join the party freely.Invited Players Only:
Only players that the owner invites can join the party.
I think you can invite people you see in-game to your party chat. The party is limited to 8 people though. So I wouldn't say it wasn't supported at all, but it was very limited.https://support.us.playstation.com/app/answers/detail/a_id/5117Edited by eclipz - 12/5/13 at 8:12am
