npc_hover_turret is a point entity available in 
Portal 2. It is a turret variant cut from Portal 2 which would have hung from the ceiling and fired a laser at the player. It remains in the final game, but is somewhat buggy.
It is hardcoded to use the model models/npcs/hover_turret.mdl, which is missing in the final game. According to early screenshots, it originally used a model based on prop_glados_core from the first game. Attempts have been made to restore this model, but currently have issues, such as the turret not being able to aim vertically.

Workaround:Increasing the cvar hover_turret_break_distmakes this less likely to happen, but also makes it harder for the player to deliberately pull the turret off the tether.
