The trailer release frequency for BioShock Infinite is speeding up, and we're not complaining.  Irrational Games has let loose another video for the hotly anticipated first person action title, centred around the game's setting --the gorgeous floating city of Columbia-- and teasing an assortment of scenes across the airborne environment. 

The year is 1912 and Booker DeWitt is headed to the city of Columbia.  A technological marvel amongst the clouds, Columbia holds a dark secret, and with it, a mysterious girl.  Upon arrival, Booker discovers that rescuing the imprisoned girl will be more difficult than he could have imagined. 

Watch the clip below, and count down the days until March 26th 2013, for PC, Xbox 360 and PlayStation 3.
