I just was surfing through and found this idea and it dawned on me how epic it would be

London
If you've ever seen Children of Men, then you know that the British government is set to soldier on through the end times of the world. It only feels natural that this should apply to a the post apocalypse as well. There's no reason to leave London out of things, especially when you consider how tightly the United Kingdom always seems to come together during a crisis. Remember all of the actual fallout shelters built during WWII, and how there was the extended Blitz of Britain? Nearly nine continuous months of bombings did nothing more than strengthen the country's resolve.
But deep beneath the London tube system, farther down than the most rat-infested sewer systems lies: the British Vault Project. Originally intended to be part of the larger vault system in the United States, Britain's government quickly took over the control and installation of their own series of vaults, hiding them beneath existing public works excavations and projects so as to hide their construction. But due to tax cuts and setbacks, as the bombs start falling, they aren't complete yet. You have to scramble to find the last partially operational vault, and seal yourself inside while Big Ben collapses and Parliament explodes around you. Hidden beneath Trafalgar Square, you'll find that getting in is just as hard as getting out.
Imaging the tubes and underground would have a proper fallout 3 feel to it
