So here's the deal, I am not so skilled at making much in this game (compared to others). But I have great ideas which need to be made at some point.
This is one of them.
The idea is you have a normal set-up for a freely moving ICE (Internal Combustion Engine), but have jet engines on the top side of the pistons that Activate when the piston reaches a certain point in the space it inhabits. That forces the piston the down, like in a normal ICE.
Please someone make this dream come true, I would love to see it happen.
