I kinda wish they had waited on this for Bioshock3 as a tribute to System Shock, but if its awesome, well then....your off the hook 2k.
@fusco1980 If you'll notice before it replays a movie there's a small cancel on the video screen as it's counting down, you click that as I just did and there's no annoying auto playing of movies. More on topic, I agree, it's good finally having some single player dlc, especially in a game like Bioshock, which is just best that way.
You know, I never thought the concept and premise behind BioShock was ever being milked until now. I'll have to wait and see, this "Thinker" looks to be like a crazy AI which could be interesting. Hopefully more interesting than Sophia Lamb, Andrew Ryan was tough villain to live up to but Sophia Lamb just seemed like the polar opposite for the sake of having a polar opposite. I will keep my eye on this DLC though.
