Ghostbusting

"There are ghosts, and not all of them are benign. When a living person steps into the world of ghosts, someone has to be on hand to help him out. Ghost hunters look for ghosts. Mediums talk to ghosts. Occultists study ghosts. Ghostbusters make sure the ghosts don’t bite — and bite back if they do." - Ken Hite

What if ghosts aren’t really supernatural concepts, but creatures with their own biology? And if ghosts have their own biology, by using scientific principals, they could be thwarted – if not destroyed, at least captured. And if ghosts can be captured... well, then somebody might get rich doing it.

Enter the Ghostbusters. Cobbled together by a group of misfit scientists, they attempted to use parapsychology for profit and, at least some of the time, succeeded. In the 1980s, ghostbusting rode high on a wave of increased supernatural activity and, thanks to a lot of strange science the Ghostbusters averted many paranormal disasters.

By the end of the 1980s, Ghostbusters were dealing with the supernatural, the unexplained and the just plain weird. Life as a Ghostbuster is never predictable. The wax and wane of supernatural activity seems to vary without rhyme or reason – with supernatural phenomena spiking wildly in far-flung regions across the country.

As the world changed, so too did the nature of ghostbusting. With a heightened awareness for global terrorism, the psychic energy matrix of the Earth was boiling with anger, fear, and hate – ghosts became more common than ever before.

And what do you need when the world is gripped in fear and suspicious of everything that moves? You need more Ghostbusters: men and women who, backed by bizarre technology, blast streams of barely harnessed energy at whatever you’re afraid of, and doing it with a smile and a small service fee. Thus Ghostbusters International was born.

Despite the fact that ghostbusting involves a bunch of people playing with proton beams, ghostbusting isn’t only about blowing stuff up. In fact, most ghosts have a history that needs solving. In this respect, Ghostbusters is a lot like a Scooby Doo mystery, only the bad guy never pulls his mask off at the end because it’s his real face.
