Please explain to me what built in VoIP Ps3 users have? The only one I have ever found requires you to be in a friend chat, which can not be active while your in a game or anything. Also skype does not work on ps3 either. The problem is dungeon running. On ps3 its hard to effectively communicate with your team. Honestly, I don't think it can be that hard... Borderlands 2 had amazingly easy co-op connection and VoIP.
