Turrets can be free-standing, wall-mounted, or ceiling-mounted. Each turret has three different modes that can be indicated by the color of its light. When a turret is passive its light will be green. If a turret is on alert, searching for a potential target, its light will turn yellow. When a turret finds a target, its light turns red and it becomes hostile.
These turrets have a body, barrel, and motors. Turrets will actively track targets and may become aware of an enemy from a few rooms away. Some turrets are linked to terminals and may be shut down. Not all turrets connected to terminals will be affected, however.
There are three main types of turrets in Appalachia. There are the ceiling and wall-mounted bubble turrets that can be found in pre-War locations around the wasteland. The second type is the turrets that are floor mounted and were/are used by different hostile groups such as raiders and super mutants. The third type is settlement turrets that the player character can build to defend their C.A.M.P.
These turrets can be mounted on walls and ceilings. While inactive they are immune to all forms of damage. A hatch on the dome will open and expose the barrel and combat inhibitor when tracking a target.
Pre-War Laser turret
These robot emplacements were used in many security systems in places such as vaults, corporate buildings and military installations. When hostile they will attack targets with a single laser repetitively, much like a laser rifle.
These turrets can be built by the player character to defend the C.A.M.P. Each one provides a defense to a C.A.M.P. and will assist when attacked. Machinegun and heavy machinegun turrets are self-powered. Laser, heavy laser, shotgun, and missile turrets must be powered by a generator and stop working if the generator is knocked out. Enemies will target generators when attacking. Prior to patch 22.214.171.124, turrets used much more of the camp budget than were used by other items. That patch greatly reduces the budget cost for turrets and limits total turrets in a C.A.M.P. to 10.
Semi-automatic laser gun on a tripod. It requires power to function and has a lower rate of fire than the machinegun turrets, but makes up for it in accuracy and range which allows it to be placed in very high places effectively.
