Hover Turret



The Hover Turret (also referred to as the Lazer Turret) is an unused turret from Portal 2. While the turret's programming is still in place within the game's files, it lacks a model; spawning it with a code or placing it with a level editor will result in a blue "ERROR" placeholder model appearing instead. In a prerelease screenshot, was shown to share the Curiosity Core's model; instead of hovering, it was suspended by a cable from the ceiling.

It can be spawned in-game using the cheat command.

Functionality
Like the standard Sentry Turret, the Hover Turret is initially inactive until a player enters its range of sight. The turret fires a blue-colored laser that hurts (and eventually kills) any player that it touches in a manner similar to a Thermal Discouragement Beam. Unlike a Thermal Discouragement Beam however, the Hover Turret's laser does not limit movement and cannot be used to activate Thermal Discouragement Beam receptacles.

The Hover Turret itself is not stationary, and will rotate to follow the player.

If the player makes contact with the turret, the cable supporting it breaks, and it will drop to the floor. If caught before making contact with the floor, it can be carried and will not fire its laser until placed gently on the floor, when it will then resume firing upon the player. If not caught, it will explode after a brief countdown.

Trivia

 * Like other npcs, the Hover Turret has a script file in the  folder; however, none of the corresponding audio files were shipped with the retail game.
 * While the original model is missing from the files, a fan-made patch can be downloaded that restores most of this npc's functionality.
