In an effort to give players the chance to play old games on current hardware, Microsoft have added six new games to the Xbox One's backwards compatibility library, this week.
Assassin's Creed: Brotherhood and Call of Duty: Ghosts are the two marquee Xbox 360 titles that are now available to you at no additional cost if you already own them. Alternatively, they can be bought via the Xbox Store.
Radiant Silvergun, Blazing Angels: Squadrons of WWII, Cyber Troopers Virtual-On OT, and Wolf of the Battlefield: Commando 3 round out this lot of back compat games.
Head here for a full list of every backwards compatibility game on Xbox One.
