EA and Warner Bros. Interactive Entertainment Announce that the Harry Potter and the Half-Blood Prince game is hitting stores this week for most platforms, from Windows through mobile. The game should be on shelves in North America today, and in Europe by the end of this week. Word is: "In the game of Harry Potter and the Half-Blood Prince, players return to Hogwarts™ – reproduced from movie blueprints in exacting detail - to help Harry survive a fraught sixth year. Players will be able to master gesture-based spell-casting as they explore the Hogwarts school grounds, from the heights of the Astronomy Tower to Professor Slughorn’s Potions classroom in the depths of the dungeons and iconic locations in between such as the Gryffindor™ common room and the Great Hall."
