The game offers an original and engaging storyline, which links to events, characters and gizmos from the two films. The story as well as appearances of classic phantoms and locales from the series are among the saving graces of the game.
Gameplay itself is not the strongest component of the game, while there is more than just simply blasting ghosts and the proton packs are periodically equipped with upgrades, the gameplay is a bit simple and becomes quite repetitive. Though proton packs can be used to move objects, nullify the effects of negative slime and open doors, the means of capturing ghosts is effectively the same and becomes old very quickly. Basically, you blast away at a ghost until its energy is depleted, then slam it by swinging the Wii remote in various directions when prompted by the game. Now the ghost is finally ready, you are able to deploy the trap to permanently snare the ghost.
That said, most of the environment can be destroyed, but don't worry about incurring penalties for the damage you caused. In the storyline, the city of New York agrees to pay all damages inflicted by the Ghosbusters. The amount of damage you cause impacts the rating you receive at the end of each chapter. The use of the P.K.E. Meeter creates some strategy as ghosts will often hide in inanimate objects. The device is also useful for seeing traps and following the tracks of a fleeing phantasm. The meter is also used to scan ghosts. Throughout the game you collect pages from Tobin's Spirit Guide. The pages contain images of certain ghosts as you try to match up scans with pages. It appears to be a means to induce replay value.
Also, be prepared to do most of the work yourself. Though you are often accompanied by at least one other Ghosbuster, they don't contribute much and frequently become incapacitated, relying on you to revive them.
