Pardon our dust! We are pushing a patch live today. 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.
Moving this over to #Destiny. Bungie posted an Achievement/Trophies list [url=http://www.ign.com/wikis/destiny/Achievements_and_Trophies]a while back[/url]. We don't know if this is the full list or not. Check them out for yourself!
