Halo: Spartan Assault is coming to both Windows Phone 8 and Windows 8. It marks the first time in the franchise’s history that it won’t be on console or PC. It’s also the second time there will be a departure in gameplay from the series trademark first-person shooter experience. This past week at //BUILD/ we learned a bit more about the upcoming game. We also have a better picture of when it should be on your Windows Phone 8 device – the middle of July.
