BioShock: Infinite will see the return of series creator Ken Levine, the masterbrain behind the genius first game and takes the action out of the waters of Rapture and into the cloudy skies.
It looks as though you'll play as former Pinkerton agent, Booker DeWitt who is sent to the airborne city of Columbia to rescue a young woman named Elizabeth, who has been imprisoned since childhood. Forming a close relationship with Elizabeth, you'll augment your powers with hers and attempt to make good your escape from Columbia before it falls out of the sky.
Apparently, you'll have numerous powers and weapons at your disposal to fight battles both indoors and outside amongst the clouds. It sounds to us like you'll be soaring on high and engaging in some form of intense aerial combat.
