BioShock Infinite from Irrational Games was hailed as one of the best showings at E3 Expo 2011. We got a chance to check out the game first-hand and really thought it looked like a unique and polished experience. Irrational Games is releasing the second in a series of videos from BioShock Infinite by Ken Levine. This week’s video focuses on the factions in Columbia and the conflict that’s tearing the floating city apart.
