Irrational Games have released a new behind the scenes Bioshock: Infinite trailer, one that focuses on the voices behind protagonists Booker and Elizabeth, Troy Baker and Courtnee Draper.

We suggest you watch this. Bioshock creator Ken Levine and Booker’s V.A Troy really push Courtnee to the limits, to the point where they force her to tears to deliver a really heartfelt line of dialogue. It’s a really beautiful piece of acting.

Just a heads up, this video contains some very strong language. Check out the TGL interview with Troy Baker right here.

BioShock: Infinite hits PlayStation 3, PC and Xbox 360 in 2012.
