The full Lamb of Columbia trailer for Bioshock Infinite has now hit, and we have to say we're now more excited than ever over the game.

Released on 26 March for Xbox 360, PS3 and PC, the game moves the action from under the ocean to above the clouds, as you have to rescue a mysterious woman from the sky-city of Columbia. But all may not be as straightforward as it initially seems.

The new trailer reveals far more of the plot and feel of the game than we've seen previously. Elizabeth,  whom you need to save, has powers and abilities that are clearly pivotal to the plot. You also get to see the "villain" of the piece, Comstock.

What does come across is how much more variety and light there is in Infinite over the first two games. And that it seems more social and less remote. It's looking like the extra few months of development time - considering the title's delays - may well have paid off.
