Quoted from LesManley:
When it starts you hit any shot to light that shot for 1x for the mode. If you hit the Gozer target first before locking in a shot, it will up a shot to 2x. Try locking in the left ramp as it is the easiest and most repeatable shot. Key here is to bring in multipliers since 50 million x2 or x3 then x6 can make your score go through the roof. Hit lit shots and he steps on cars as you progress. You can milk the left ramp for a long time, but not entirely through the mode. Last 3 shots I believe start him on fire and then the final shot to destroy him.
Thanks for your feedback, highly appreciated. I am not sure that I understand that correctly. Does it mean that the first shot locks this shot and thus repeating this shot will not progress the mode, but increase the score only? After this shot I simply shoot at the other lit targets until stay puft is destroyed. Is that correct?
Why do you choose the left ramp as first shot and not the right orbit, which I think is easier to hit?
