On the official site for Harry Potter and the Deathly Hallows Part 2, fans receive a tutorial about how to launch an exclusive augmented reality experience using copies of Part 1 and 2 of both games based on the films. After downloading a program to their desktop, fans can reveal a hidden Lord Voldemort by holding up the front cover of the Part 2 game to their webcam to unleash the Dark Lord in our interactive Augmented Reality experience. If you have Part 1 of the game, you can hold that up at the same time for an extra magical surprise.
