One of the best new additions phased in with the New Xbox Experience UI is the Guide. Think of it as a highly evolved form of the Xbox Guide menu that used to pop-up in-game while using the Xbox 360, only minus the clunky controls and slow response times.
The Guide gives you a live update on what your friends are playing, messages in your Inbox, notifications from your console and Party options and settings. All you need to do is press the Xbox button twice in-game or flick the left analog stick to the left while on the Home screen.
