Two more backwards compatible Xbox 360 games have been added to the Xbox One. These games are Syberia and Boom Rocket. You can download either game from the Xbox One Store for 10 dollars, or if you have bought either game on the 360 Marketplace, they will be available to download on the Xbox One. If you have a physical copy of Syberia, just putting the disc in will let you download it. Sadly, there never was a physical release of Boom Rocket, so you would had to have owned digitally on same account you are signed into on your Xbox One.
