The Silo The Silo is a in the " " " Lonesome Road " . Detailed walkthrough . Approach the bunker from the Pass to Canyon Wreckage . At about the halfway point , a large pipe will allow one to climb a hill to the southwest . Northwest from the pipe is the Hopeville silo bunker entrance . Entering the bunker takes the Courier to a sewer access tunnel that leads straight into a wrecked room . Halfway down the tunnel is the graffiti " " You can go home Courier " " and near the door to the next room the graffiti " Lonesome Road " is painted . In the first room of Hopeville missile silo bunker , there are locked doors to the north and south . In the middle of the room is a control panel that needs to be activated , in order to proceed north into the silo , but it is " " encrypted beyond your ability to hack . " " The south door has an unlocked terminal next to it that unlocks it . Walk through the south door and follow the path around and to the left . The path leads to a maintenance area . As the Courier enters , they will pass a commissary terminal on the wall . The room is decorated with empty robot pods , and inside the robot pod on the south platform is ED - E . Release ED - E by interacting with the maintenance computer next to its robot pod . After talking to ED - E and recruiting him as a companion , ED - E then proceeds to tell the Courier that he can disrupt terminals with small satellite like dishes on them . Bring ED - E back to the console in the main room and he will proceed to return power to the silo door control terminal . Throw the switch on the console and watch the doors open as the silo powers up . The newly - accessible hallway has a door to hydraulics access level three that can only be unlocked by accessing the locked terminal ( easy ) next to it and an unlocked door at the end of the hallway which leads to the missile silo proper . In one of the hallways , one will find an Eyebot upgrade circuit board for the ED - Ecated challenge quest and corresponding Camarader - E perk . It can be found lying in the middle of the hallway behind the door to the left of the entrance , looted from a destroyed eyebot . Inside the silo , on level three , there is an overturned desk next to the stairs leading up . Climb up to the second level ; ED - E plays another log on the way up . At the top of the stairs is a room defended by several turrets and a , which can be disabled by interacting with the terminal outside the room . A locked ( Hard ) desk has Hopeville silo - 1st level security code . Up the stairs is a storage room with a couple of dead marked men . Leave the storage room to see the irradiated top floor of the silo chamber . To player ' s immediate left is a damaged security terminal , a turret , and a door , in that order . A roams this floor . If one repairs the damaged terminal ( requires Repair 50 ) , they can compromise the security , causing the turret to attack the sentry bot ( or vice versa ) . The sentry bot frequently attacks the turret with missiles and even if the player is sneaking , they can be caught in an explosion if they are not fast enough . Across the way , to the west , enter the large doors . Reminiscent of the Vault Overseers ' offices , this chamber has a circular Base Commander desk with some codes needed for the mainframe . A science skill of 75 is required to access this terminal . The ghoul corpse of the base commander himself , General Martin Retslaf , lies in his chair next to an empty bottle of and a . A terminal allows one to deactivate Retslaf ' s sentry bot security and open the doors to the sentry bots . Return to the silo chamber and this time go south , into the main entrance area . There ' s a destroyed sentry bot and two dead marked men with arc welders in the main room , and a door that cannot be opened ; to the right ( west ) is a mainframe . Using the codes obtained from the base commander ' s desk , have ED - E unlock the mainframe and open the silo ' s doors . Upon opening them , several turrets and will attack . Compromising the security makes the turrets friendly , thus making this battle much easier . When finished , follow the quest marker up to a door that leads to Hopeville and finish the quest .
