People like zombie video games? Go figure. State of Decay has sold more than 500,000 copies since its June 5 release on Xbox Live, making it the service's fastest-selling original game of all time. A Steam version is still in the works, says Undead Labs.

Xbox Live is doing away with Microsoft Points when the Xbox One launches, Microsoft's Marc Whitten just said at E3.

If you'd rather watch video games than play them on your console, Twitch.tv has the app for you, available for Xbox Live gold subscribers today. The app makes the top 300 live channels available for spectating. No streaming from the 360, only viewing. There'll be more at the next Xbox reveal in a week.
