"FILE - In this Dec. 7, 2012 file photo, Ken Levine, creative director and co-founder of Irrational Games, presents the world premiere of ""BioShock Infinite"" on stage at Spike's 10th Annual Video Game Awards at Sony Studios, in Culver City, Calif. Levine is hoping the companion character, Elizabeth, provides a new depth to ""Infinite,"" one that wasn't reached in the original ""BioShock,"" whose voiceless protagonist didn't have a sidekick. It's been a daring and daunting endeavor for the game's makers, especially considering Elizabeth was originally envisioned as a completely mute and scripted character.
