Complete B-L-A-C-K and H-O-L-E drop targets in order for "G-Force Accelerator" lower PF multipliers. 2x for first bank, 3x for both banks.
Complete either drop-bank on lower playfield to open reentry gate
go for the ball lock on lower playfield at first. If your ball drains, the locked ball is not lost (instead of the lock on upper PF)
When re-entry from lower level achieved, send ball ball back downstairs on first shot to keep re-entry gate open.
Multiball can be brutal and short. There are good points in getting the Accelerator to 3X and focusing on the lower playfield.
4 yellow standups to light upper saucer. Lock a ball in both captive holes. Gravity Tunnel starts 2-Ball. 3-Ball MB starts after re-entry.
Upper capture ejects after each ball, lower capture doesn't, but can be stolen by other players
2x lower playfield will carry over from ball to ball. If you get 3x, then drain, the multiplier will be reset to 1x.
4 yellow standups light the right return lane. Ball through lane opens re-entry gate, then shoot spinner to play lower level with re-entry.
