GamesAreEvil writes, "At heart, much of Fallout 3 boils down to matters of economy. That's what's driving The Pitt, where rulers have resorted to slavery in order to power the city's vital industrial machinery. The big cheeses are unable, and unwilling, to fund the necessary research to determine why Pittsburg's residents are falling victim to a toxic, mutative and rather unpleasant disease. This condition results in transforming citizens into ghastly Trogs.
Which is why, after forking over 800 Microsoft Points, one escaped slave recruits you, the dashing, intrepid adventurer of D.C's Capital Wasteland, to infiltrate The Pitt: so that he and his enslaved brethren can wreck a bit of havoc on Ashur, the despotic warlord running the show. The game justifies it in two ways, first as the chance to do the right thing for good character or just end up with a fat reward and some tasty loot if you're playing someone more morally dubious. But, really, you're just playing it to soak up a bit more Fallout. Which is no bad thing...."
