Microsoft has added a couple more games to Xbox One's backwards compatibility library. Two more Xbox 360 titles are now playable on the current-generation console. Microsoft's Major Nelson revealed the new additions via Twitter.

The two new backwards compatibility games are Earth Defense Force 2017 and the Dreamcast classic Sonic Adventure 2. The former title was a physical release, while the latter was only available on Xbox 360 digitally as an Xbox Live Arcade title.
