Like its predecessor, BioShock Infinite aims to generate a complex emotional response in the player. To that end, series creator Ken Levine has been working closely with the game's voice actors to get the right performances. A new video shows off some of this (sometimes arduous) process.

Entitled "The People Behind Booker and Elizabeth Pt. 2," the video features Levine and actors Courtnee Draper (who plays Elizabeth) and Troy Baker (who plays Booker). It's a very enlightening look at the process, notable for an almost uncomfortable sequence where Baker verbally berates Draper to help her get in character for a particularly fraught scene. The footage of the actors delivering lines is juxtaposed alongside the same dialogue in the game.
