Quoted from shacklersrevenge:
I'm trying to figure out what builds your bonus. I got the 8x max at the top lanes, the next completion of the rollovers lit extra ball at the right ramp. When I drained my ball I only had 400,000 with 8x bonus!? I know an earlier game I had maybe a 2x bonus and a million or so, so I'm curious to know what builds it.
pretty damn sure each hit to "Scully" and "Mulder" targets add 10,000 to the bonus.
Nothing unbalanced in the scoring at all, no double your score or 100,000,000 point shot. even the super jackpots aren't that many points and take about 10 timed shots to get...nothing easy about it.
I love the game, glad haters kept the price cheap so I could land one!
