We will be pushing a patch live tomorrow. Players will be required to log in to Destiny again after returning to the title screen to install the patch. You should not be removed from any activities you are currently in.
Talk about games other than Destiny. We don't mind.
More friends (from what I've read)
Gears of War
Destiny early content
Uncharted/Last of us
So basically just exclusives. Take your pick.
