Yeah, I was trying to work out from the videos if this is a clear trapdoor with lights underneath, like an insert?One annoying thing with the pro....unless I've got this wrong....it doesn't have the pop up trap door mech to the dungeon, however as stern only make one playfield these days it just has a blank in it's place,. right in the middle of the playfield.
Does look like an interesting machine, I'm looking forward to playing one.
