Dark Souls and Tekken Tag Tournament 2 are the latest Xbox 360 games to become backward compatible on Xbox One. Microsoft confirmed on the Major Nelson blog today that these games are now playable on Xbox One.
The announcement coincides with Microsoft rolling out an update to Xbox One owners that allows them to purchase Xbox 360 games directly from the Xbox One's Marketplace. This is a feature that Preview Program members have had access to since earlier this month.
Microsoft announced that Dark Souls would be joining the list of backward compatible 360 titles last month when it offered the game as a pre-order bonus for Dark Souls 3. Those who purchased the upcoming game in From Software's hardcore action series on Xbox One received a download code for the earlier 360 title, which launched in 2011.
Earlier this week, Xbox 360 games like Assassin's Creed also became available to play on Xbox One.
