Halo Wars, Soul Calibur 2 HD Online, and The King of Fighters ’98: Ultimate Match are now backwards compatible on the Xbox One.
The King of Fighters ’98 is a fighting game fiasco with a side of real-time alien-shooting strategy, and a remake of the original 1998 KOF ’98 game, which came out in North America in 2009. Halo Wars is a real-time strategy game from Microsoft and Ensemble Studios while Soul Calibur 2 is a fighting game that debuted on consoles in 2003, with an HD version landing on PlayStation 3 and Xbox 360 in 2013. That version’s now available in Xbox One’s backwards compatibility lineup today.
