The dark'n'mysterious picture of what manner of beast Batman: Arkham Asylum may be is becoming clear. Beneath the cut, footage straight outta GDC of the Splinter Cell/Metal Geary Invisible Predator mode.
You can also find my initial thoughts on that and another of AA's modes (a high score attack one, very much in the the vein of The Club) in a big ol' preview piece over here, based on a few hours of hands-on perp-thumping earlier this week. While I've yet to try the PC build, so far it's looking like a pretty slick superhero game as they go.
Invisible Predator is a fun time of stalking, waiting, face-kicking and wall-exploding, but one thing bothers me - why are there so many gargoyles inside a hospital like that? I'm guessing it's so the game has a consistent, recognisable, grapple-to-this object, but it does look a little silly.
