- "Inanimate objects should not move of their own accord. Put a stop to this affront, oh, say, 20 times".
- "You have destroyed 20 poltergeist objects".
In order to get this achievement, you will need to destroy 20 poltergeist objects. One playthrough of the main game or several playthroughs of the final boss fight in the DLC pack The Writer" is a good way to do this. It is also a good idea to have the strongest flashlight for this as the darkness will burn away from the objects much faster.
- This achievement is a reference to the movie "Poltergeist", which the little girl exclaims when the poltergeists arrive through a television.
