Yes, I am the one whom you should be seeking for PS4 unlocks.
Both parties need 2 PS4 controllers each, a registered account times two and a PSN subscription to enable multiplayer if attempting a two player unlock. Guest accounts disable online play, so they can't be used to acquire the unlock.
My PSN ID is Tilarta.
I have the PSN chat software installed on my iPad and if I am shown as online, this means it is turned on and I am available for multiplayer gaming/chatting.
finished TWILIGHT OF THE REPUBLIC playset, after a six hour plus play today ..... so it was a short one for me then and just the 2nd and 3rd jedi training arena missions to do, not the races and collectathons though
