Fallout 3 The Pitt DLC Interview

The latest issue of Game Informer contains a special on Fallout 3's second downloadable content, The Pitt. Included is an interview, which contains some new info on the DLC. Two of the questions:
GI: What's the narrative setup for The Pitt?

Gardiner: Pittsburgh was once the industrial center of the pre-war world. The city was spared the horrors of nuclear fire, only to have its people infected by a nightmare plague of disease, infection, and mutation. The Pitt opens with the player encountering an escaped slave from Pittsburgh, Pennsylvania. The slave, Werhner, claims that the leader of (the Pitt) has created a cure for mutations. Once inside the Pitt, the player will have to figure out how to gain audience with the raider boss. What they'll discover could send shockwaves through the Wasteland. The Pitt is very morally ambiguous there's no real right or wrong, just choices to be made, sides to be chosen.

GI: What new features/creatures/weapons/locations can players expect to encounter in The Pitt?

Gardiner: Without spoiling everything, The Pitt contains all of the above! There's an (AutoAxe,) a melee weapon comparable to the ripper but with a huge, serrated rotary blade. There are three new perks including (Auto Axpert,) which will give the player a boost in damage when they're using the new AutoAxe. Pittsburgh itself is infected with (Trogs,) creatures that were once human but slowly devolved into scampering mutants who fear the light and fight in packs. Many iconic locations in Pittsburgh are modeled in the game; several of our developers are from the city and their first hand knowledge is on full display!
Thanks, Ausir.
