Those of you who have read the Harry Potter books will know that the franchise takes a turn for the dark-side in the penultimate novel, Harry Potter & The Half-Blood Prince, as Master Potter and Dumbledore make preparations to thwart the fast approaching threat of Voldemort.

It's a trait which has clearly been taken seriously by EA's video game adaptation of the movie as the trailer looks notably moody.

The Harry Potter games have actually been really good in the past, so there's quite a bit of excitement on our part for this one. The game is due out at the end of this week.
