The Xbox One has added three more Xbox 360 titles to its backwards compatibility lineup. Halo Wars, Soul Calibur II and King of Fighters '98 are now available to play on Microsoft's newer console. If you already own the digital copies of these games, they'll show up under Ready to Install in your Xbox One's Games & Apps section.
The new additions were revealed on the Major Nelson Twitter page. Halo Wars is the real-time strategy game set in Microsoft's Halo first-person shooter series that was originally developed by the now-defunct Ensemble Studios in 2009. Microsoft has announced plans for a sequel, Halo Wars 2, for the Xbox One and Windows 10 that is being developed by Total War's The Creative Assembly. It is currently scheduled for launch in late 2016.
Soul Calibur II is the fighting game from Namco Bandai that was first released in 2003 for the original Xbox and other platforms. The version of the game made for the Xbox 360 that can also be played on the Xbox One is Soul Calibur II HD Online, which offers higher definition graphics. Finally, King of Fighters '98, a 2D fighting game port from SNK, was released for the Xbox 360's Xbox Live Arcade back in 2009.
