BioShock Infinite's Elizabeth promises to be one of the most advanced companion AIs ever to grace a video game. A new video shows us the women behind Liz's magic and gives us a peek at some of what we'll see when we play the game.

Ken Levine and the crew from Irrational Games repeatedly extol her virtues every chance they get and it serves to make us more excited about running around Columbia with Liz. The video introduces us to some faces that might be familiar to anyone who has been following Infinite's development. We spend some time with Courtnee Draper, Heather Gordon, Amanda Jeffrey, and Anna Moleva. Respectively, they provide Liz's voice, motion capture footage, design, and face.

A lot of the video discusses how these four women were integral in making Liz feel like a real person, rather than just some video game character that was scripted to say something or act a certain way. For example, instead of just standing there and waiting for Booker to go somewhere, Liz will lean up against the wall and cross her arms, letting Booker know that he's cheesing her off.

Watch the video below and let us know whether or not you're more excited to go on adventures with Liz when BioShock Infinite comes out next week on March 26th, 2013 for Xbox 360, PC, and PlayStation 3.
