In the latest developer diary for Bioshock Infinite, Ken Levine explains how Elizabeth interacts with tears in the world of Columbia. The tears are objects which exist on a different plane, that only Elizabeth can interact with and bring into the world. As you can see from the video below, exactly how you’ll be interacting with the objects is going to be dependent on the choices you make.
These tears will be scattered throughout the world of Columbia and depending on how you choose to play, you can request that Elizabeth bring them into the world for you to utilize. Bioshock Infinite is coming off of a huge E3 2011, where many publications voted it as the best game of the show. Have a look at the video below as well as the latest screenshots from the upcoming shooter.
