Poltergeist

The Poltergeist is a hostile Typhon encountered on Talos I during Prey (2017).

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.

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

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.

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.

The lift field can be used as an advantage if you encounter a Nightmare and Poltergeist at the same time. Its lift field allows you to go upwards, which increases the chance of survival by going to where the Nightmare can only resort to ranged attacks to get you.
