The Nintendo DS version of Ghostbusters: The Video Game is radically different from other versions. It is more of a squad-based tactics game, where you control one Ghostbuster and the others follow your character (or not, depending on orders). Touchscreen controls are used for shooting and interacting. Although it follows the same plot as other versions, there are also random missions for earning money and collecting slime (both of which are required for researching new tech). The random missions have randomly-generated maps, much like the Diablo games, with new location types unlocking as you play the story mission associated with that type.
