Irrational Games has released the second part to their retro-themed documentary trailer series "Columbia: A Modern Day Icarus", continuing the 1980s style expose on the mysterious floating city with a look at the game's most iconic monster character, Songbird.

While Irrational hasn't elaborated on the meaning of these videos, it is presumed that they tie into the game's narrative with some manner of time-bending, and that the mysterious cabin chronicled in the documentary is a result of the player's exploits in BioShock Infinite.

Check out the new part 2 trailer below, and be sure to check out part one if you missed it.

BioShock Infinite is due on PC, Xbox 360 and PlayStation 3 on march 26th 2013.
