Quoted from StevenP:
Vengeance interacts? Ah, no. Never comes near the ball. Just a plastic toy connected to a solenoid that bounces occasionally. Nothing else there. A spinner and a 3rd flipper. Tron is pretty basic but it has the arcade scoop by the right inlanes, and the spinning disc with lowering standups. That one little device is more than you see in the whole ST pf, sadly. I would hypothesize that Stern is cutting the BOM of every new game by an additional 10%, except MET actually has interactive stuff on the pf. Not a ton, but some.
Wrong. Acts as virtual lock, and shoots the ball back during Vengeance Multi-Ball. Also, the player and the Vengeance engage in shooting each other virtually with the vertical strip of lights and the Punch It button.
Premium/LE version also crashes into the play field, and there may be more interaction in that mode.
