After reaching the end of the pass to Canyon Wreckage, there is the Hopeville silo bunker entrance which leads to the Hopeville missile silo. The Hopeville missile silo is a large facility, extending all the way on the other side of the map. The entrance is a standard bunker door leading onto a hallway that leads into the main room. On the right is a door that leads to a bot pod, unlocking the ED-E copy. A RALPHIE poster for the Feel Like A Kid Again challenge is found next to the computer used to activate ED-E. On the left is an L shaped hallway with a maintenance closet. Leading onto the silo door is a broken duraframe eyebot. In the center of both rooms is large computer like system to restore electricity to the building and giving access to the latter of the two rooms. Beyond the door is the missile. There is a terminal on the far right that can deactivate a sentry bot in the next room.
Inside the silo (holding the rocket), to the left in the corner, is an overturned desk next to the stairs leading up. The desk is locked (easy) and contains the Hopeville Silo - 2nd level security code. It removes the lock on the turret control terminal one level up.
Two Nuka-Cola Quartzes, one is next to the maintenance bot control terminal (south side), and the other is inside the room with the sentry bot, under a desk in a box with two regular Nuka-Colas.
Given the solid construction of an ICBM bunker, coupled with its construction inside of a mountain, the entire facility has an alarming tilt, likely caused by the massive upheaval of the Divide's formation.
