Machine gun turret

Machine gun turrets are a type of turret encountered in The Commonwealth in Fallout 4.

Background
They are employed by pre-War coporation or military installations to serve as supplemental, unmanned security units, capable of selecting trespassing targets and engaging them.

Specifications
Machine gun turrets can be mounted on the walls or ceiling and are fitted with a dome to contain the parts and seal them when the turrets is not actively tracking targets. Some turrets may even be waterproofed, forcing them to shut and become inactive when submerged in water.

Gameplay attributes
These turrets have a body, barrel, and combat inhibitor selectable as targets. The combat inhibitor is on the opposite side of the barrel, making targeting it harder in combat. With the Killshot perk, the barrel will be significantly easier to target in VATS.

While closed and submerged in water, these turrets will not take damage from explosives or gunfire.
