Even if you've collected or missed the other skill shots the left crossover shot stays list for a skill shot combo sequence at the beginning of the ball. Shoot it then the upper loop or side ramp, and repeat for up to 6 shots.
Left ramp is very backhandable.
Soft plunge into the drop targets to get one of the van modifications to boost your next mode, or go for bigger points with a plunge directly to the left outlane.
You can start Area 51 multiball while one of the Overlord multiball modes is running, but not the other way around.
To activate 2x Playfield, shoot the Right Orbit into the "Rock-O-Meter" lane 3 times. 40 seconds. Repeat during this timer for 3x Playfield.
Soft plunge to flipper for a free shot
Best mode combos are: LA / Seattle with Area 51, New York with Bot Frenzy, Sonic Radio with New Orleans. Great point scoring / MB building
Hit UFO captive ball a few times to light the action button, then hit the action button to spot a lit shot.
You can hold up to 3 UFO button charges (yellow = 1, green = 2, red = 3) and bring them into a mode or multiball.
Start with New York since you can progress using just the spinner.
