Looking for more background on the tears I mentioned in our first look at BioShock Infinite?  Perhaps a bit of a explanation as to how they got into Columbia in the first place?  Luckily Irrational Games creative director Ken Levine heard you, since he's talking about the Tears -- these windows into other worlds -- in a new video released today.  The tears that Elizabeth can manipulate allow for a unique gameplay experience based on the choices you make.  Super exciting, yes?  I thought so.
