GameTrailers has a very interestingBioShock video of going on the prowl for the game's Big Daddies. Melissa Miller, 2K Games' Content Producer brings us the walkthrough and gives us the rundown of what we'll be seeing. It showcases security hacking, and the teleportation, enrage, telekinesis plasmids. While there is a "Work In Progress" watermark at the bottom, it still looks very nice and sets the atmosphere with the ambient music and constant sound of water flow. Rather than spoil it for you, we'll let you see for yourself. So, can you take on a Big Daddy?
