Sentinel Site

The Sentinel site is a location found in the Glowing Sea in Fallout 4.

Background
The Sentinel site was a pre-War military instillation that was working to make "Mark 28" air dropped nuclear bombs compatible with newer ICBM delivery systems. Later on, the facility was discovered by the Children of Atom, who were able to activate the structure's launch before being massacred by the feral ghoul inhabitants. While no missile was present to be launch, the facility still locked down all internal blast doors, requiring the player character to shutdown the sequence to open access to full structure.

Captain Dunleavy's holotape reveals that a lot of the military personnel stationed at the site on the day the Great War occurred were nervous because communications were down and multiple launches were being detected but because of the communications being down, no one knew if it was a drill or the real thing. Sadly it was the latter.

Layout
The exterior of the Structure is a concrete pyramid, with a large blast door entrance on the North side.

As the Sole Survivor enters the facility you find yourself in a rather tall room that looks somewhat like a missile silo with some catwalks going through it. In the room down the stairs to the left you will find the Sentinel site blast door override holotape that will open the blast doors in the facility. Here you will also find a copy of Astoundingly Awesome Tales on a control panel. At the bottom of the facility you will find three unused nuclear warheads in metal crates and a fourth on a forklift. They will not detonate from gunfire or explosions but nearby there will be a horde of feral ghouls hiding in a rather long tunnel. At the end of the tunnel there is a lift that will take you to a second exit; not marked on your map. When the lift is called a feral ghoul will appear guarding crate with minor loot. (edit:)whomever keeps editing these layouts needs to provide more info, or none at all. this is about the 5th or 6th location description in this wiki that is either wholly inaccurate or very non-descriptive. thanks.
