I noticed a large 3.3 gig download for it come to find out its a free dlc    (Now Microsoft has shut down Games for Windows Live, what happens to the one use anyone had for it--buying the Minerva's Den DLC for BioShock 2? Thankfully 2K has switched over to Steamworks, updating the game and very nicely giving the add-on free to everyone who already owned the base game. For goodness' sake, play it if you haven't already)
