Two more Xbox 360 games are now playable on Xbox One. Microsoft's Major Nelson has announced that Injustice: Gods Among Us (as well as its disc-only Ultimate Edition) and Haunted House have been added to the backwards compatibility program.
If you already own Injustice or Haunted House games, they should show up automatically in your Xbox One game library. If not, you can pick them up on your Xbox One or through these links: Injustice ($20; 7.8 GB), Haunted House ($5; 282.5 MB). As mentioned, Injustice's Ultimate Edition requires the game disc.
These are just the latest additions to the Xbox One's backwards compatibility catalog. Earlier this week, Microsoft added The Elder Scrolls IV: Oblvion, AstroPop, Medal of Honor: Airborne, and Trine 2 to the catalog. There are more than 280 games in the backwards compatibility library; you can see the complete list of supported games here.
