As teased yesterday a new BioShock Infinite trailer called Lamb of Columbia was released today. The two minute game play trailer reveals a number of scenes involving Elizabeth, the woman DeWitt is sent to Columbia to "wipe away his debt", although in the trailer DeWitt can be heard saying "the deal is off...". The full story behind Elizabeth will obviously not be known until the game is released, but scenes and a few lines of dialog seem to hint at Elizabeth being the daughter of the Zachery Comstock, the leader of the Founders faction on the floating city of Columbia.
As with previous BioShock Infinite trailers that have been released, the game looks fantastic. Development has to be in the final stretch as there's just one month left until the release on March 26th, 2013.
