Combine Ground Turret

"Uh-oh! Turrets! H-hey, you've got the HEV Suit, you deal with them! Then I'll work the security console."

- Barney Calhoun

The Combine Ground Turret is a sentry weapon used by the Combine.

Overview
Ground Turrets are only encountered in the Overwatch Nexus. They are built into the floor, and have scanners which are used to detect intruders. When a Ground Turret detects an intruder, the Floor Turret comes out of the floor and starts firing on the intruder(s). To destroy a Ground Turret, one must throw or roll a grenade into the turret's hole in the floor, which makes the turret withdraw back into the floor.

Trivia

 * The Combine Ground Turret has no animations.
 * The Combine Ground Turret have close to exactly the same behavior and firing radius as the turrets in Portal, excluding vocals. However, the turrets in Portal can sense when a person picks them up and will stop firing.
