Xenobiology Map Overhaul

The point of the cyan pipes is to flood the cells with a specific gas / remove the gas from the cells if the scientist wants to do so.

-> That is why everyone of them leads to their own connector port for a gas canister.

I see, but there isn't any pump going back to the canisters, so one gas is put into a line, that's it, there's no way to get it back out of that specific line and back into the canister is desired. However I can see that's probably not necessary given the size of the laboratory and number of cells.
