Video: the sounds of Batman: Arkham City

Warner Bros Interactive have released two videos showcasing the voice actors and audio artists behind the sounds of Batman: Arkham City, in a bid to build up expectation ahead of the game's special Game of the Year edition, due out in August.

The voice acting video in particular is really impressive, as it shows master voice actor and Star Wars star Mark Hamill performing his interpretation of The Joker, a character he has played since the cartoon series in the early 90s.
