After hearing about the expansion update way too late btw, I have thought about maybe when they do the update for them to add moderately sized tanks on the outside of the facility that stores all of the liquids used in the crushers. And make them destructible allowing them to break or explode and spill out the contents (depending on the contents within of course).
I just would think that it would be cool show us where the gas for the flamethrower is coming from, the liquid nitrogen from the freezer, the acid, etc.
Pictures of what the tanks could look like:
For the gas supply for the flamethrower
For the liquid Nitro for the freezer
For the acid
I know it might look ugly on the map, but I think it is a good concept.
