As anticipation for the upcoming BioShock Infinite hits fever pitch, Irrational Games has released a couple of new videos related to the game. One is a US TV Commercial for the game (a 30 second spot with an extended version promised to follow later), and the other is a recording of Creative Director Ken Levine's recent appearance at BAFTA.

Titled "From Shodan, to Big Daddy, to Elizabeth: The Evolution of AI Companions", Levine's BAFTA presentation and Q&A is quite lengthy, at over an hour and 44 minutes, but its recommended viewing for anyone interested in the work and philosophies of one of the most respected and celebrated creative minds in the games industry. Catch both videos below.

BioShock Infinite launches on March 26th for PC, Xbox 360 and PlayStation 3.
