Halo: Spartan Assault and Max: The Curse of Brotherhood are now available to download for free on Xbox One for Xbox Live Gold subscribers.
Xbox One’s Games with Gold promotion went live on the console alongside the June system update—that is slowly rolling out to all users—earlier today. On Xbox 360 a new free Games with Gold title is unlocked on the 1st and 16th of each month, but on Xbox One it appears that both titles will be free to download for the entire month.
Once downloaded you can play both of these titles for free, even after the promotion ends, as long as you keep your Xbox Live Gold subscription active.
Currently on Xbox 360 Dark Souls is available to download for free as part of Games with Gold until June 15.
