The latest trailer for BioShock Infinite delves deeper into the mysteries surrounding the woman at the heart of Booker's adventure.

From everything we've seen so far about BioShock Infinite, we know Elizabeth is going to be the key to something. We don't quite know what yet, but she's played a central role in almost every bit of promotion to this point.

However, none of the trailers before focused on Elizabeth quite so much as this most recent one. We get to see a great deal more of just what she's capable of, and we see more of the darker side of Columbia.

There's still a month to go until BioShock Infinite arrives, but Irrational has us chomping at the bit to get our hands on this sequel. Check out the trailer below, and let us know if you think it's possible BioShock Infinite is going to live up to the hype.
