HBO's epic fantasy series Game of Thrones returns this Sunday and if you a) have an Xbox b) are an HBO subscriber and c) own an iOS device or Windows 8 tablet, you're going to want to download the SmartGlass app ahead of the premiere.

If you're the type that multi-tasks when watching TV, then you're going to dig all the "exclusive" content you'll have access to while watching the show. The app will include the following: "interactive maps, detailed character guides, cast and crew commentaries, behind-the-scenes extras and more."


Winter is coming. Or ending depending on where you live in the world.
