"But the coolest thing the LE and Premium versions have is something you won’t see in the images or teaser: An interactive holographic projection of famous ghosts to battle. Dankberg describes this feature saying, “We call them the Ecto Goggles, and when peering through the Ecto goggles, you'll be able to shoot various ghosts who are not really there.” Using a reflection trick and an LCD screen, The Librarian, Slimer, and the Scoleri Brothers appear hovering on the playfield. Dankberg continues, “There [is] a sensor switch there that will note you went to it, and it'll change where you hit it and explore or splat or whatever it might be. So, we've put a ghost into a Ghostbusters machine.”
