The Real Ghostbusters
Meikyuu Hunter G - Japanese title
This is done by first shooting the ghosts using a gun, and then by using a photon beam (by holding down the fire button) to suck them in for storage in the backpack. Photon recharges can be collected, as can the potential for an improved shot, as well as a shield. The Ghostbusters mascot Slimer also appears as a power-up, which hovers around your character killing ghosts on contact.
