Poltergeist

"'Ghostly denizen of a world unlike our own.' - Unit Description"Poltergeists, introduced in the level Haunting of Nevada House, are support-like enemies that attack from far distances. Very few Poltergeists appear in the level, and gradually spawn the higher the wave you are in.

They do not seem to be carrying any weapon. They usually avoid fighting with their fists, and mainly use their projectiles to attack.

Appearance
Unlike the rest of the ghosts, Poltergeists have their entire skeleton showing, from the skull to the pelvis. Their head is a skull, and their rib cage, spine, and pelvis bone is exposed. Their hands and feet are completely normal. Their outline is also green.

Personality
Poltergeists do not have any personality. No text chatter, no dialogue, nothing. It isn't even clear if they are able to talk or not.

Abilities
Poltergeists can shoot green, skull-like projectiles (similar to Phobos') that can home in on you. They do not do much damage. Like the other ghosts, Poltergeists can phase through walls and objects.

Trivia

 * In the files, Poltergeists are not named after their name, but named "Spectre3".
