Nick's description and Todd's video explain the game well. From a gameplay perspective, it has a typical GTB SYS 80 ruleset, which is fairly deep and has a difficult multiball.
The game looks simply stunning - artwork is really cool. Spinning disk adds a bit of mystique into the theme. Backglass is incredible. The game was designed by John Trudeau, who created CFTBL.
It is a rare title that I've only seen for sale once in the last 10 years. They never change hands. That's because the game is a keeper.
