Quoted from Sinistarrett:It looks like this game has some sort of working simulated smokestack?
From the website:
As an industry first, we implemented an Interactive Smokestack system that simulates factory smoke. The Interactive Smokestack system can be triggered during gameplay by catching puns, during ball launch, and while the machine is in pinball attract mode.
How do you suppose this works?
Might be the little oil based systems some model trains use. Or the ultrasonic water based versions, both cheap ways of creating fog. But one leaves water vapour every where and the other oil lol
