Batman: Arkham Asylum game director Sefton Hill walks us through one of the game's challenge rooms, demonstrating exactly what they mean by "invisible predator" gameplay.

This is one of the games that really makes me regret not making it to the Game Developers Conference this year. I'm a relatively large fan of Batman, but I've been burned by bad game after bad game. To see Crecente speak about the game in glowing terms actually has me hopeful.

At the the very least, if it ends up disappointing me I now have someone to blame.
