Duck, you fools! That incoming chopper isn't a friendly. It's an Xbox Live service alert, bristling with notifications as to hang-ups with Call of Duty: Black Ops 2 and Battlefield 4 multiplayer on Xbox 360.
If you're playing either, you may have trouble "accessing all game features" or "joining other Xbox Live members in online games". Apparently all this is due to scheduled maintenance on the part of EA and Activision. "We'll provide an update when more information is available."
While you wait, consider reading about why Frostbite became EA's definitive "next gen" game engine, or how Activision reckons this year's Call of Duty will benefit for spending three years in development.
