Microsoft continues to add new titles to Xbox One's backwards compatible library. Major Nelson has announced that two more Xbox 360 games are now playable on the current-gen console, following the lone title that was added last week.

Headlining the newest batch of backwards compatible games is Assassin's Creed IV: Black Flag, the 2013 installment in Ubisoft's stealth-action series. While the game was also released on Xbox One, players now have the option to play the 360 version on the console. Joining it is Divinity II: The Dragon Knight Saga, the 2011 action RPG by developer Larian Studios.
