Quoted from Eskaybee:

I'd like to add a wishlist item:
- After beating/playing Showdown. The game should end - and you should get this end of game victory celebration of some sort plus a final end of game ball bonus; like 1 mil points for every extra ball you did not use, plus some other end of game bonuses like how you did overall or such. I know this sounds unorthodox-ed compared to what we're used to in pinball. But think about it, you beat the game....and now you start over with disasters again?

Quoted from Eskaybee:

I thought about this too, and when I beat showdown I did notice that kickback wasn't relighting even though it would say kick back is now lit. I also thought, oh they should use the magnets and attacks, almost forcing the players game to end. And while that would be fun, it doesn't make sense in a story lore format. You just beat the corporation yet now they're fighting you even harder and more abrupt? Not sure if that fits the story line.
An end with credits and way to go music has never been done in pinball. Fits the story line on this pin to do it IMO.
