I have a friend who has Destiny for his 360, and I was wondering - if I was at his house and logged into the game as me - if my characters/progress/inventory would be downloaded to that console without nuking my saves at home? I know people can transfer UP to the Xbox One when they upgrade from 360, but can I transfer DOWN when visiting? I'd like to show off my Level 30 Warlock so he can tremble before my awesomeness :)
