Multiple Profiles?

Just acquired the Xbox One with H5. Set my grandson up to play with my account creds and he is already 3/4 of the way through the game. I would like to setup another profile (or whatever it is called), so that I can play separately from my grandson, in my own game. That way I do not pick up where he left off, I just want to start a new game. Is there a way to do this?

Mmm he is playing with you account and it is link to your email. The only way I know is creating a new profile with a new email.

There are three save slots so you can run separate campaigns.

Online MP is a different story
