http://www.gametrailers.com/video/batman-arkham-home/55021 Here's a video showing the PlayStation Home Batcave, a place where you really shouldn't host impromptu dance parties.
The Batcave is a special treat for PlayStation 3 owners who pick up Batman: Arkham Asylum, first announced and shown off earlier this month. It looks lovely, but once again I must stress how much Bruce Wayne would frown on using his secret headquarters to impress ladies who might be men.
