Just bought a HUO Tron and it's sweet! It's super satisfying once you figure out how to hit the gem shot to just nail it from Quorra (hint: you have to hit the ball while it's away from the wall!). I also love how bonus makes such an impact on score, as well as making combos (raising that end of line). The 100 mil shot is probably one of the most satisfying things in pinball, but is also super frustrating because your entire game can be ruined if you screw something up... for example, I had everything completed except clu, but I was screwed because I couldn't start it without starting Sea of Simulation :'(
