Fallout: New Vegas

Follow the Main Storyline for this Achievement

As a Point of Reference, you will complete these items below before the Achievement unlocks:

1) You receive prompt after installing Lonesome Road DLC that is a message from Ulysses.
(This begins quest "The Reunion")
2) Go to "Canyon Wreckage" (Map Location) and Enter
3) Follow your Map Markers and Finish the Quest "The Silo"
4) Follow your Map Markers and Finish the Quest "The Job"
5) Follow your Map Markers and Finish the Quest "The Launch"
6) The Final Objective in "The Launch" will gain you this achievement - It is activating the console right outside of the Ashton Silo

Note: Remember to use your laser detonator to clear areas to get to your map marker

Simple. It's part of the main story line. You have to launch the nuclear missle that is in an underground silo. Once you get through "The High Road" area make a left to the construction site. Once you enter the construction site make a left and have ED-E override the control switch as he has done throughout the DLC and then hit the "A" button to engage the nuclear missle then boom...Achievement Unlocked.

*Safety Spoilers*



When you reach the Ashton Silo Control Station there will be a station outside the entrance that ED-E can access and a switch. When you activate the switch a missle will launch and the achievement will unlock. You need to reach this location anyway so I don't believe you can miss this.
