Hot on the trails of The Elder Scrolls IV: Oblivion and Medal of Honor: Airborne, a couple of new games have found their way over to the Xbox One backwards compatibility program. Available to play on Xbox One right now, Injustice: Gods Among Us (and its disc-only Ultimate Edition) and Atari's Haunted House have been added to the program. Haunted House is the 2010 sequel to the 1982 classic Haunted House, which is one of the earliest examples of a survival horror game. If you don't have either Injustice or Haunted House, you can purchase them through the Xbox store.
