PlayDevil has posted a review of the second DLC for Fallout 3, "The Pitt".
Here's a snip:
""Firstly, you need to enter the complex as a slave, which forces you to rely on your wits far more. Additionally, nearer the end of the expansion, you get to make some pretty cool, and also very tough moral choices. You really have to think about them, because whichever way you go, it blurs the lines between what is really good and what is really bad."
