The Pitt is now available via Games for Windows LIVE as well as Xbox 360 (where problems have been reported). Here is word on this DLC for Fallout 3, Bethesda's RPG sequel: "The latest exclusive Marketplace download allows you to travel to the post-apocalyptic remains of Pittsburgh, Pennsylvania and become embroiled in a conflict between slaves and their Raider masters. Explore a sprawling settlement ravaged by time, neglect, nuclear radiation, and moral degradation. The Pitt is filled with morally grey choices, shady NPCs, new enemies, new weapons, and much more."
