Alien turret

s (simply called Turret ingame) are the alien equivalent of Automated Turrets, encountered on board Mothership Zeta.

About
In contrast to Automated Turrets, only ceiling-mounted versions of this turret exist. While they cannot be shut down or frenzied via a terminal it is possible to remotely detonate them using nearby switches aboard the mothership.

Appearances
s appear in the Mothership Zeta Fallout 3 add-on.
