Honestly I read about it on another forum, perhaps that's what they were doing and I misunderstood? It seemed popular, I think they called it the 'Rat Trap.' I'm still quite new and haven't been able to play any games due to the current crisis, entirely possible I misread it all.
::Edit:: Looking at it again I think that's what they meant. Stick Khemist in Gunhauler with compartments, use 'Always a Breeze' combined with auto 6 run, use the bottle. Sorry, still learning all the rules.
