Electronic Arts' chart-topping Harry Potter and the Order of the Phoenix videogame is now up on Xbox Live in downloadable demo form, so if you're into that, accio like a mother-f-.
At 510MB it'll eat approximately 2.55 percent of a 20GB hard disk, which is the sort of useless fact we like to offer you here at Eurogamer, and you can read much more about it in our Harry Potter and the Order of the Phoenix Xbox 360 review.
Don't expect it to go anywhere in the charts soon, either - with the game having achieved its back to back success in the UK Charts before the film it's based on had even gone on general release. Magic!
