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 pre-release screenshot, it was shown to use the model of the cores from the first game, switching between them depending on its state: it used the Curiosity Core's model when firing at the player, the Anger Core's model when on the ground, and the Morality Core's model when facing away from the player. Despite its name, the turret does not actually hover, but is suspended by a cable from the ceiling. The eyes of the turrets firing at the player were a slightly different shade and glowed more than the Curiosity Core's. It can be spawned in-game using the cheat command ent_create npc_hover_turret, and can also be placed through Hammer. Special thanks to the Portal unofficial wiki!
