"Driving the Ecto-1 is an exclusive feature for the Nintendo DS version of the game," Red Fly's Dustin Dobson said, "although it will certainly play a big part in all of the games." Sadly for the Wii version, there are no plans as yet for a proton pack attachment, as far as Dobson knows. "But whether or not an official pack accessory is made, I am sure custom ones built by fans of the movies and games are going to pop up! I am excited to see what people come up with." Somebody buy one of the movie props and mod it. You guys have money. You can do this.
