Microsoft wants a 'Halo' for Xbox One

Microsoft's $100M Halo 'critical' for XBox

The latest version of Microsoft's $4.6 billion video game franchise — "Halo 5: Guardians" — launches around the world Tuesday. And this game is particularly important, and not only because it's part of Microsoft's most valuable game franchise — and cost a reported $100 million to produce.

"Halo 5" is exclusive to Microsoft's Xbox console platform, making it a key weapon in Xbox's battle with Sony's PlayStation. In fact, with the Xbox One lagging rival PlayStation 4, the appeal of "Halo" is considered a key way to help Microsoft recoup its investment in the gaming platform.
