Can play with a friend on the same console.
EA has revealed that Harry Potter and the Deathly Hallows will support Kinect on Xbox 360 on its release this November. At the publisher's gamescom conference the game was demoed live on stage by James and Oliver Phelps from the movies - aka Fred and George Weasley.
The two played as Harry and Ron and moved through the level in an on-rails fashion. There appeared to be some lag as the pair cast spells and targeted enemies.
In addition to versions for Xbox 360 and PS3, Deathly Hallows - Part 1 and 2 are also in development for Wii, Nintendo DS and PC.
