Real? Totally unreal if you ask me. Take on the underworld on your own, or with a friend, and tackle the spirits over ten gruelling levels, with just a hand gun and your proton beam between yourselves and the next dimension.
Utilising some phenomenal graphics, your task is to go out creature hunting. Using either of your weapons you can kill off the nasties and transform them into ghosts. Once you've done that, use your proton beam to zap them and store them in your backpack.
At the end of each level, you'll come up against a particularly nasty ghoul, who needs to be defeated before you can progress.
With friendly Slimer around to give some added protection, keep your eyes open for power-ups, and don't let your proton beam get too low, or the show could be over.
For some excellent action and well thought out gameplay, Ghostbusters has got to be worth looking at.
