A Barrel is the placeholder name given to an item seen in the E3 trailer. Barrels can be f filled with oil via the currently nameless Oil Structure. Barrels are seen moving between Storage Tanks and Oil Plants (both of these are guesses as to the function of the structures).
Speculation[edit | edit source]
So far, as we have not seen any pipes, the assumption is that all liquids exist only as barrels which can be sent between machines on belts. The only liquid that is currently known is [oil]. [features] []
