It was already announced. They are generally told in advanceHow do you know what games are going to be free next?
I'm actually looking forward to this one. Possibly the first XBO game with gold I felt really looked interestingIn January D4 (dark dreams dont die) will be free.
Its really good and weird.
This x100They have yet to release a free game I am even slightly interested in. The Games for gold on the X1 is pretty sad to me, considering how much the system costs it would be a nice promotion to give away a real game. And its been out for over a year and there quite a few release titles they could give away without hurting themselves.
