As we reported a few days ago, Xbox One's Games with Gold are changing.
We will now be getting two games instead of one a month and it starts next month with Assassin's Creed IV and So Many Me.
Now the dates of the availability have been shown, Assassin's Creed will be available through the entire month of July and So Many Me will be around from July 16th to August 16th.
If you haven't played Assassin's Creed yet, you should consider giving the true open world Assassin's game a shot. You cab't go wrong for free.
