Question 3.
The shift keys do something different on each table. For example, on "Ace of Space" one of them switches the lane changer. Before you shoot the ball off, see the lights at the bottom of the table (Little LEDs on the left & right of the flippers) Press one of the Shift keys & you'll see the two lights switch from one to the other, then, when the ball goes round that Hyper ramp thing (Straight up the middle, it'll come out in a different place depending on which light is on.
Phew! Mess about, that's the best bet. Look for changes etc...
FuZion.
PS. Great game! One of my faves.
