Help with your villain modes - try and start one just before the multiball.
During multiball (right when it starts is best), hold the lockbar button down for 2-3 seconds to switch the "channel" back to the villain mode.
Theres no need to have the multiball "channel" running ... you know every shot is points.
When you change channels, the inserts will be showing you where to aim to complete the villain mode. Try and hit them!
Don't forget to light the inlanes for MYSTERY and spank the left orbit to get your add-a-ball for the MB.
I could be wrong - but I don't think you can ADD TIME to the villain mode from MYSTERY when the MB is running. If you can, it would be after ADD A BALL as that is always first.
If you are running the Villain mode in single ball play, ADD TIME is invaluable. It will always be the first MYSTERY award during a villain mode.
Running 2x or 3x playfield multipliers during the Villain modes can be very lucrative. ADD TIME will also add time to this, as well as the Villain mode.
