Did i just see Batman ?

Enemy saw Batman but did not want to believe it. This is in The batman Arkham Asylum Demo that is out now. Go Download it. Its is really fun. I think what happened there was that The enemy has a animation of him turning but it is not really his field of vision that is moving. His sight is still looking forward. I dont think this is a glitch but it is Funny to look at.. perform silent takedowns on all guards in the last part of demo just before you confront the Joker again. There is a guard at the far middle of the room. He is underneath a gargoyle. Position yourself upsidedown and then drop down. And move the camera so you can have a good view. He wont see you.
