Machinegun turret

Machinegun turrets are a automated defense found in the The Commonwealth in 2287.

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. Over the years they have been further utilized by various factions to secure territories held by said factions. The Sole Survivor may also build these turrets to fortify settlements against attackers.

Specifications
A turret is made of of a body, motors, barrel, combat inhibitor, and either tripod or column legs. Turrets under raider control may also be held in old shopping carts. They have varying types of ammunition based on the Mk version of turret, some using 5.56mm rounds or incendiary 5.56mm rounds.

Gameplay attributes
Turrets will actively track targets and may become aware of an enemy from a few rooms away. The barrel of the turrets are more likely to be hit with the Killshot perk. Some turrets are linked to terminals and may be shut down or even made to serve the Sole Survivor if they have found the Total Hack issue with the Turret override program. Not all turrets connected to terminals will be able to be affected by this program however.

Settlement creation
The variants may be randomly created in settlements using 8 Steel, 1 Circuitry, 2 Gears and 2 Oil. The standard Mk I, Mk III, Mk V and Mk VII turrets do not require power from a generator to function. If destroyed in an attack, materials used to build the turrets must be expended to repair them.

Machinegun turret Mk I
Machinegun turret Mk I's are the most common, and also weakest turret type available. They have decent amounts of health, and use a basic machine gun which deals reasonable amounts of damage in short periods of time.

Machinegun turret Mk III
Hardier than the normal Mk I's, Machinegun turret mk III's use explosive 10mm rounds.

Machinegun turret Mk V
Mk V Machinegun turrets are tougher than existing versions and use incendiary rounds. However, they fire at a slower rate.

Machinegun turret Mk VII
These turrets use explosive 5.56mm rounds, and are only found in certain locations.

Bugs

 * The invisible "root" of the Machinegun turret is separate from the visible base of the turret, and can be thrown a considerable distance away from its original location if the turret is destroyed. If this happens to a hostile turret which respawns, the respawned turret will be placed wherever the root object landed, not where the turret was originally placed.  This can cause turret placement to seem to be randomized during repeated visits to a location.

Appearances
Machinegun turrets appear in Fallout 4.
