for: map -> greyfold -> bomb pit -> bunker, the code is 810674. for: map -> N-085 bunker -> enter -> left door -> A3, the code is Andrew. u can buy a gasmask at the ruins fashion, in east greyfold. and lastly, u can buy a black rollie at the tribal village storehouse, which once you consume it at the bunker, will give u the 1 more intelligence u need 4 the missiles. Hope this helps.
