Xbox One grabs 360 games 'Halo Wars' and 'Soul Calibur 2 HD'

All hail backwards compatibility.

The Xbox One is beefing up its library via backwards compatibility, allowing players to boot up some of their favorite games from the Xbox 360. This week, Xbox One users get Halo Wars, Soul Calibur 2 HD Online and The King of Fighters '98: Ultimate Match. It's a fighting game fiasco with a side of real-time alien-shooting strategy.

Halo Wars is a real-time strategy game from Microsoft and Ensemble Studios, and it first hit the Xbox 360 in 2009. The game was largely well-received, though development was rocky and it ended up being Ensemble Studios' final title. Ensemble founder Tony Goodman said in 2012 that the game wasn't originally Halo-themed, but Microsoft thought it would perform better if it carried a recognizable name. Plus, Bungie, the studio that created Halo, was never into the idea of Halo Wars, Goodman said.

Current Halo developer 343 Industries and Alien: Isolation studio Creative Assembly are working on Halo Wars 2 for Xbox One and Windows 10. Last we heard, that one was due in fall 2016.

That's enough about Halo.

Soul Calibur 2 is an immensely popular fighting game that debuted on consoles in 2003, and an HD version landed on PlayStation 3 and Xbox 360 in 2013. That's the version hitting Xbox One's backwards compatibility lineup today: Soul Calibur 2 HD Online. The King of Fighters '98: Ultimate Match is a remake of the original 1998 KOF '98 game; it came out in North America in 2009.
