The hat is the key. You know it.

The demo of Warner. Bros new Hogwarts-'em-up Harry Potter for Kinect is now available for download from Xbox Live.

The game, which is based on all eight of the Harry Potter movies, allows players to scan their face into the game so that they can create a unique witch or wizard to study at Hogwarts School of Witchcraft and Wizardy. A Kinect-exclusive, Harry Potter for Kinect promises to provide Quidditch matches, Death Eater battles, and of course, a smattering of mini-games. Co-op play is also on the table.

Strangely, the demo doesn't provide any snippets of the main story, instead focusing on three mini-game examples. You'll be able to play as the Seeker in a Quidditch Match, go all Indiana Jones as you steer a cart through the underground caverns of Gringott's Bank, and battle Death Eaters across the Hogwarts bridge, attempting to defeat them as it collapses.

Harry Potter for Kinect will launch on October 12th in the UK and Europe, and we'll get our wizard hats on and bring you a full review as soon as we can.
