Down on the Wii version of Ghostbusters, are you? Think it's too casual, too cartoony for your tastes? That's because you're not in possession of all the facts. Red Fly - the dev team behind the Wii/PS2 version of the game - have said that in the Wii version, you'll be able to wirelessly connect your DS to the Wii and...use it as a PKE Meter. For real! As real as a full-torso apparition! And just as amazing.
