These shiny white oblong pods have a red seek light and are normally found in a dormant state. When intruders are detected, they activate and actively seek for targets. They fire a machine gun like projectile at high speed.
 In Portal
In Portal the turrets are very fragile and have a very upbeat, friendly personality. They often quip different humourous statements such as:
"I don't hate you" (when you defeat them) and "Time to sleep" (when they go from active state to a dormant state).
Defeating the turrets is very easy. If they are pushed over they fire wildly for a moment before shutting down. A turrent will only detect you from its front. There are 3 simple strategies for overcoming turrets:
- Portal behind them and tip them over
- Open a portal above them and drop something (such as a Companion Cube) on them.
- Open a portal beneath them in order to drop them somewhere else.
