If enabled, hold the buy-in button when starting Air Challenge. Keep holding and hit Skydive @ 25M. You'll be awarded 50M and a MK3 code.
"No Limits" mini-wizard mode, all shots lit. Every shot collects and builds value by 1 mil. Caps out at 70 million a shot. Very lucrative.
"Meet Your Maker" wizard mode is the most lucrative mode in the game. Time out modes to get to it. Jump ramp worth 200 mil a shot.
Every jump ramp adds 5 million to bonus, which becomes huge. Successive combo jump ramps gives big points too (up to 25 mil a shot).
In MB if you shoot the left saucer, it will hold the ball for about 10 seconds.
In normal multiball, jump ramp is worth a flat 20 (?) mil a shot. If shot is repeatable, this is more lucrative/safe than the jackpots.
Passing through an inlane briefly lights the opposite orbit to score a Raceway award. These score 5M, 10M, 15M, 20M and Extra Ball.
Hit the ramps to start Payback Time (like T2), making all shots worth 25m
