Automated turret (Fallout: New Vegas)

Automated turrets are automated, stationary laser and machine gun systems which appear in the Mojave Wasteland

Specifications
Automated turrets can be mounted on the floor or the ceiling. The ceiling turrets use 5.56mm machine guns whereas the ground turrets are equipped with lasers, although some ground mounted 5.56mm machine gun turrets were built. Both variants have unlimited ammunition.

Gameplay attributes
Automated turrets are often found in military installations or areas of historical value. Although not too damaging at lower levels, they can be quite deadly if they surprise you. Both types of turrets can be frenzied by shooting either the targeting chip (on ground units) or the lens (on ceiling units). Then, similar to frenzied insects or robots, the turrets will fire on everything they see.
