For all you "Halo" fans out there, Microsoft's got something cooking. Exactly what, we're not quite sure, but a recent job listing drops hints at "large-scale testing of the out of game Live experience by gamers across the world."

From the Careerbuilder job listing:

We're looking to blend console, web, and mobile to create an immersive Halo world that follows the dedicated Halo fan wherever they go. We need engineers that can build connected technology while working in a startup environment.

Does that mean Master Chief will be coming to a Windows phone (or, gasp, some other platform) near you? That's not yet clear. But it has been tried in the past, and we know Microsoft's putting more emphasis on gaming with the upcoming Marketplace. We'll keep our heads on a swivel.
