Have been searching around for this game for my son and the cheapest we have found on DS.
"Altogether now... "I ain't 'fraid of no ghosts!" After a couple of decades of absence, the Ghostbusters franchise is back. Egon, Peter, Ray and Winston are back in town and ready to clean up New York City once again from the threat of paranormal activity. Take a trip as one of the original Ghostbusters and revisit some classic locations from the films as you learn more about the history of Gozer, the silent librarian and why the Stay Puft Marshmallow Man is still kicking around. The Nintendo DS version of the game assumes a more cartoony look for the Ghostbusters universe, creating a comical adventure that can be enjoyed by gamers of all ages. Use the bottom screen to direct the action and catch ghosts in your protonic stream, while the top screen displays important information on your chosen character and inventory. As a team based game, the four Ghostbusters need to work together if they have any hope of beating the ghoulish threats ahead. Members of your team can fall behind and get injured, and it's up to you to make sure you all stick together as a unit. The more you progress, the more cool weapons you can add to your proton pack, including a Slime Blower that throws goo all over enemies and reveals hidden pathways. Drive around town in the Ecto-1 to reach your next destination. Once more, with feeling; "Bustin' Makes Me Feel Good!"
