First things first... go to play, select table, go all the way to the right for the “Special” table as it is unlocked from the start. Load the table and plunge your ball with “A”. A timer starts counting down from 30sec.make some shots, trying to wipe out the first wave of baddies and you’ll hear “Locks Lit”. I think it has to do with time as there isn’t much to hit on the table. Now, those three saucers near the top right of the table are open to lock one ball in each. Again, try to wipe out the first wave to restart your timer and lock two more balls as quick as you can. As soon as three balls are in the saucers, multiball starts and achievement unlocked. See my guide under the achievement for playing til wave 30 for some tips on how to play the multiball. Happy hunting!!
