One of the features of the 3.0 software update was that people could make third party accesories to play the games with. This IPad keyboard dock would probably help me/you play fps on the ipad... you use the W A S D keys to move and the space bar to shoot, to aim you swipe your finger on the screen! The only problem is that you would have to play it in portrait mode... This will be a turn on/off option incase you dont own this accessori.
Funny coincidence But i do think this will work perfektly! And it seems like alot of people have ordered the keyboard dock too! And playing a fps game in portrait mode will work...i mean it worked for Left for dead!
