core each and every time we hear him. And this latest trailer for Batman: Arkham Asylum starts off with a great Joker narration, but it doesn't stop there. Adding to Joker's dialogue is plenty of Batman-kicking-ass action. Watch the world's greatest detective employ his powers of stealth, as well as his powers of wealth through the use of his high-tech gadgetry. This trailer is set to air tonight on MTV, but thankfully Totilo posted it early for everyone to drool over, so check it out after the break while we run out to the store for a new keyboard.
