We really like this walk through because we are sick of video game walk through narrators who try to act funny every freaking 5 minutes. It is getting ridiculous.
In case you are in need of a Bioshock Infinite guide, this can really help you out. This walk through is really more of a guide, and will help you through the game if you are not familiar with it. It will most certainitly not unlock all of the secrets, but it does do a pretty good job of getting you through the game.
