The second part of the developer's diary featuring creative director Ken Levine and voice actors Troy Baker (Booker) and Courtnee Draper (Elizabeth) has been released as we're given additional insight into how they work with the script and how the world of Bioshock Infinite comes to life with the aid of actors and voice. It's really interesting to see the emotional investment that goes into the game, hopefully it will translate into something even more memorable than the first Bioshock.
