Last night, I finally beat my Twilight Zone, and got into "Lost in the Zone" multiball. I made good progress the first couple of weeks, but recently I'd been hampered by the current location of the machine (due to remodelling), which leaves it slightly off-level and with a light reflection right above the flippers. But, I'm lazy, so I didn't try to fix it.
To get to "Lost in the Zone", you have to collect a whole bunch of door panels. You are rewarded with a 6-ball timed multiball in which all the high-score jackpots are enabled. The hard part is actually making any shots (you really can't aim) without hitting the other balls on the table. So, you get about a minute of this frenzy (which is plenty), then the machine goes dead, all the balls get reset, and you start trying to do it again. My score ended up being about 1.4B points.
Next up are some mods for the machine. There are enough enthusiasts that there are lots of options. Here's what I'm thinking of:
I've considered getting a "topper", which is something that goes on the top of the machine and is hooked into the lights, but that seems hard to justify right now.
