Corvega Assembly Plant

The Corvega Assembly Plant is a location in the city of Lexington in the Commonwealth in Fallout 4.

Background
In June 2077, Lake Quannapowitt reported that illegal dumping from the plant caused water contaminant levels to triple since the previous reading, resulting in a formal inquiry into the company's waste management practices. The pre-War Corvega facility is now home to a group of raiders.

Layout
Nearly twenty raiders patrol the outside of the factory, along with a single turret at the main entrance. The gangways to the east side also provide access to numerous side entrances.

There is a hidden entrance access by way of pipes that are located in Lexington between the main and eastern entrances to the factory. Inside, there's only one turret guarding the pipe (mostly against ghouls) and some noise alarms.

Jared, the raider leader, is in a small, well-guarded area near the top of the factory. He has two machine gun turrets near him along with spotlights that will alert him to nearby intruders. Once all enemies in the immediate area are killed, two additional raiders will spawn. Inside the factory, the Sole Survivor will encounter another twenty or so raiders, as well as five turrets (including the turret near the hidden pipe entrance).

Bugs

 * Sometimes when reaching the final room where Jared is, the player character's health will inexplicably and constantly drain after being hit once by the turrets. Exiting and re-entering the building should solve this problem.
 * In one of the first stairways, there is a cigarette machine that, if one backs up onto it (possibly forward too), the player character will be stuck on it, unable to move anywhere else.
 * To fix this, reload a previous save prior to entering the Plant.
