In little more than a month you'll finally ascend to the floating city of Columbia to wipe a debt and rescue a girl. Well, not just any girl, this is "The Lamb", but you'll come to know her by the name of Elizabeth.

Irrational's latest trailer focuses on your Infinite companion and what she means to Father Comstock and the denizens of Columbia, but more importantly, what she'll come to mean to you: fear. We know that Elizabeth is powerful, and we know that her being locked away in a tower in Columbia has a more nefarious purpose than anyone might have realised, but beyond that, we don't know much else, which makes this latest video all the more tantalising.
