The Official Fallout webite over at Bethesda has been updated with a developer diary from Lead Designer Emil Pagliarulo. There's a lot of interesting information and concept art about the new Brotherhood of Steel. Highlights:
...So it really didn’t come as a surprise to anyone within the
Brotherhood of Steel when the order’s ruling council, based in Southern
California, decided to send a contingent of soldiers all the way to the
East Coast, with two important objectives:
scour the ruins of Washington D.C., once the nation’s capital, and
recover any and all advanced technology. After all, D.C. was the home
of the Pentagon, the very headquarters of the United States Department
of Defense. Who knows what secrets – or equipment – they left behind?
investigate the reports of Super Mutant activity in the area. Could
these creatures be somehow related to those that fled eastward after
the Master’s destruction (as depicted at the end of Fallout 1). Or were
these Super Mutants something else entirely?
Check out the whole thing here. Definitely worth a read.
