Ghostbusters the video game has its faults, its short, a bit clunky in some places with slow down and lip-synch errors, but all this can be ignored because on the plus side, your getting an excellent, enjoyable, brilliant game.
set a few years after the second film you take the role of a new recruit, who is basically a guinea pig for the ghostbusters new equipment, and after a quick tutorial, your thrown into an excellent story, written by the ghostbusters cast! focusing around the occultist Ivo Shandor and his gozer cult (from the first film) the ghostbusters find themselves caught up in a new 'the world is going to end' adventure.
playing with the various proton pack goodies is the core of the game, as you start of with basic proton streams, up to bosun darts and good slime launchers, all of which handle well and destroy tha environment spectacularly! my personal favourite tho is using your PK meter (which puts you in first person) to find hidden cursed artifacts, or to scan ghosts to add to your Tobins spirit guide (another mainstay of the franchise.) which adds to the replay value significantly.
the game also contains many throwbacks and nods to the first two films, aswell as tying everything up, the story itself is really funny and plays out just like a film. the fact that the original cast return to voice the characters really takes it up a notch.
overall, one of my favourite games of 2009, and one that should belong on any gamers shelf, ghostbusters fan or not!
