Xbox One owners get Valiant Hearts: The Great War and Telltale's The Walking Dead (complete first season), while Xbox 360 users can pick up Metal Gear Solid V: Ground Zeroes and The Walking Dead (complete first season). See the image below for a rundown of the free games and when they will be available.
Even if you don't have an Xbox 360, it's probably still worth picking up the last-generation games, as they could one day be made playable on Xbox One through backwards compatibility.
