Automatic Turret

"Warning, automated turret guns online!"

- UAC announcer at the Delta Security Checkpoint The Automatic (or Automated) Turret in Doom 3 is a base defense weapon located in the UAC base on Mars. Designed by the Mixom Corporation as a security system, it is a large rotating gatling gun mounted on the ceiling, first seen when entering the Marine HQ. However, the demonic invasion of the facility caused the Identify Friend or Foe (IFF) program in the turrets to malfunction, resulting in the turrets targeting anything that moves.

The first encounter with a live turret is in the Monorail area, just before entering Delta Labs Sector 1. The turrets cannot be destroyed by any means, but if the player obtains Karl Cullen's PDA, which contains fail-safe codes for the turret, it can be deactivated by a nearby control console. However, if it's not deactivated immediately, the turret will conveniently kill several enemies.
