Ghost hunter

The Ghosthunter career appeared in the expansion pack for The Sims 3, Ambitions.

Sims use various machines to trap or ward off ghosts, similar to the Ghostbusters film franchise.

Ghosts and lesser spirits will randomly appear in occupied houses around neighbourhoods such as Twinbrook. It is possible that these ghosts will constitute a new category of NPC or Townie.  Ghosthunters must deal with several different types of investigations and paranormal activity in order to advance.

Lesser Spirits
Lesser spirits are the least powerful of all paranormal activity. Lesser spirits resemble wispy Halloween ghosts. They come in many colors, which represent their personality. Certain personalities are more valuable then others. For example, green spirits (who have a kind personality) aren't worth much to researchers while yellow spirits (who are frightened) are worth more.

Poltergeists
Poltergeists possess random objects, causing them to move and fly around. Poltergeists are not very powerful, but they are stronger than lesser spirits.

Ghosts
Ghosts are the most powerful of all paranormal activity. They are very hard to capture, but ghosthunters may alternatively attempt to befriend a ghost and convince them to move on.

Occasionally, ghosthunters may encounter ghosts from past civilizations. These ghosts are worth more money when sold to the science lab.

Spirit Invasions
Spirit Invasions are the most basic of hauntings. Lesser spirits are much less powerful than full bodied ghosts, and are visible at all times. Ghosthunters need only use the ghost vacuum to remove the lesser spirits. If the spirit manages to escape the ghost vacuum, they will scare any non-brave sim.

Paranormal Investigation
Occasionally, a ghosthunter will be asked to investigate a random rabbit hole. The ghosthunter need only enter the venue and stay for a few hours to complete this investigation.

Poltergeist Haunting
During a poltergeist haunting, the ghosthunter must exorcise furniture that is being possessed by poltergeists.

Ghostly Presence
During this investigation, ghosthunters must find and remove a full bodied ghost. To find the ghost, the ghosthunter must scan rooms of the house with the Spook-O-Meter (similar to the Ghostbuster's PKE Meter). After the ghost has been located, the ghosthunter can attempt to capture it. Alternatively, the ghosthunter may befriend the ghost and convince them to pass on.

Angry Ghost Invasion
The most dangerous of all Investigations. The haunted area is infested with several angry ghosts who cannot be reasoned with. The ghosthunter must capture all the ghosts.
