We are once again joined by Alistar Bloom, as a second part to the educational-style video for BioShock Infinite‘s Columbia has been released.

While the previous part went into detail about the history of Columbia and Zachary Comstock, part 2 delves into the mystery that is the Songbird, as well as its connection to the ‘Lamb of Columbia;’ who is, presumably, Elizabeth.

Man, I really want an hour long cut of this.

BioShock Infinite releases on March 26th.
