In Harry Potter and the Half-Blood Prince, Voldemort is tightening his grip on both the Muggle and wizarding worlds and Hogwarts is no longer the safe haven it once was. Harry suspects that dangers may even lie within the castle, but Dumbledore is more intent upon preparing him for the final battle that he knows is fast approaching. Together they work to find the key to unlock Voldemortís defenses and, to this end, Dumbledore recruits his old friend and colleague, the well-connected and unsuspecting bon vivant Professor Horace Slughorn, whom he believes holds crucial information.
In the game of Harry Potter and the Half-Blood Prince, players will return to Hogwarts to help Harry survive a fraught sixth year. They will also have a chance to engage in exciting wizard duels, mix and brew magical ingredients in Potions class and take to the air to lead the Gryffindor Quidditch team to victory. Players may even get sidetracked by Ronís romantic entanglements as they journey towards a dramatic climax and discover the identity of the Half-Blood Prince.
