Ghostbusters II is the title of a video game released for several home  computer and console systems. The game is loosely based on the film of  the same name.

All home computer editions were published by Activision. Each home  computer game edition of the game is essentially similar, with changes  in the quality of graphics and sound. 

The DOS version is completely different from the other ones, having been  developed by a different company, Dynamix with game design by  Doug Barnett.

Gameplay

Most version of the game feature several arcade sequences based on the  film: Van Horne: the player controls Ray Stantz as he is lowered into  an air shaft of the disused Van Horne subway system to collect a  sample of slime. He is armed with his proton pack and other weaponry  with which to defend himself against the myriad of ghosts that attack:  some will collide or grab him and cause damage, while others will  attempt to cut his rope. The player must collect the three segments  of the slime scoop, as well as ammo and health, during the descent. 

Journey to the Museum: the Statue of Liberty has been brought to life  by "mood slime" and is marching toward the Metropolitan Museum of Art;  the player controls a floating fireball (generated from the Statue's  torch) which fires horizontal shots and must be used to protect the  Statue from swarms of ghosts. Impacts from ghosts (or regeneration  of the fireball) uses up precious slime, though it can be replenished  from destroyed ghosts. 

Showdown in the Museum: the player controls the four Ghostbusters  individually, armed variously with proton packs and slime dispensers,  in an isometric 3D level. The four heroes must rappel into the Museum  and fight Janosz, Vigo the Carpathian, and finally a possessed Ray,  in order to save the world. 

Some versions also feature a sequence based on the courtroom fight  against the ghosts of the Scoleri Brothers.
