The Xbox One has added two more Xbox 360 titles to its backwards compatibility lineup, with the Tekken Tag Tournament 2 and the original Dark Souls now available to play on Microsoft's newer console. If you own the digital copies of these games, they'll show up under Ready to Install in your Xbox One's Games & Apps section.
AR12 Gaming also notes that there's a little treat for Dark Souls fans with the original game's arrival. As previously reported, those who pre-order Dark Souls 3 digitally through the Xbox Store will receive the backwards-compatible original game for free.
These are just the latest additions to the Xbox One's list of backwards compatible 360 games. Earlier this week, Microsoft added Assassin's Creed, Grid 2, and Dark Void.
