The Silo

The Silo is a quest in the Fallout: New Vegas add-on Lonesome Road.

Detailed walkthrough
Walking into the bunker, there is a console need to interact with, but you can't with your current knowledge, so head to your right and operate the terminal to gain access to the maintenance area. Inside you will find several robot pods and another terminal. Upon operation, you can release a robot, this is where you meet the ED-E (Copy). After talking to ED-E and recruting him as a companion, ED-E then proceeds to tell you 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 you power up the silo, revealing 2 ED-E copies reparing what looks like a missile.
