Poltergeist

The Poltergeist (Typhon dysmorpha) is a hostile Typhon encountered on Talos I in Prey and on Pytheas moon base in Prey: Mooncrash.

Overview
Occasionally, Weavers aren't successful in their attempts to reanimate husks. In these cases, rather than creating a Phantom, the result is a Poltergeist. They lurk out of sight, waiting for the right moment to hurl objects or throw their victims into the air.

The Poltergeist is the only known Typhon with the ability to render itself invisible. With this ability, they're masters of ambush. Poltergeists are lurkers; they find a place within their environment and haunt it. Sometimes a Poltergeist won’t even be hostile, and you might only notice it when it starts to play with objects in the environment or when throws something across the room. At other times, a Poltergeist might inexplicably choose to attack you with a lift field, which sends you floating a few feet off the ground, making you easy prey for other aliens. The Poltergeists slip in and out of the visible spectrum, which makes them a difficult enemy to get a bead on. The Lift Field power is unlocked by scanning this enemy. Alternatively the Lift Field power and the Poltergeist research data can be acquired via transferring a file from Sylvain Bellamy's workstation.

On Pytheas, not only are the Poltergeist able to generate lift fields and to throw objects at their target, but they are also able to try and grab any object held in hands by their target, being sometimes able to disarm them.

Design
They look like a deformed version of the Phantom with thin springy arms that it uses to move, and seemingly unusable legs and two eyes instead of four.

Strategy
Ways to counter attack it include firing the GLOO Cannon until it is caught, or at least fire a few shots before it blips out of vision so you can track it. It is extremely weak against the shotgun, and unlike its less annoying counterpart, the Phantom, it lacks a melee attack, meaning that if you can get close, a few shotgun blasts should be able to take it out.

You can also use Psychoscope vision to track it, however it does not always show up. 1v1 is really easy even with wrench alone. Be careful to look at the floor, so you can see the lift field coming. if you get trapped in the lift field, use the Artax Propulsion System (found in the Hardware Labs) to escape.
