This is a list of locations that can be found in Fallout: Post Nuclear Warfare.
Built by the inhabitants of Vault 8, the sprawling Vault City is one of the smallest, safest, and most isolationist settlements in all the Wasteland. Heavily protected and surrounded by large walls, Vault City is one of the cleanest and medically advanced places around. Too bad they don't let anyone inside the city except its current inhabitants.
Though New Vegas may be bigger and more intact than New Reno, the biggest little city in the world still has two successful casinos, a booming drug trade, and is run by mafia families that, though they keep the city safe, are quick to 'whack' anyone who tries to disrupt the flow of business.
Inside of a dark, radscorpion-ridden cavern lies a broken door leading to the insides of Vault 13. Within, intelligent Deathclaws and humans live side by side, surviving off the vault's tech but having no idea why the vault was abandoned when they entered it long ago...
A massive, wide open desert and all that remains of the West Coast after the Great War. It's filled with various mutated creatures and vile roaming bandits, so have a gun ready and some stimpacks close if you want to make it out here.
