Ever felt like oil was a bit ... difficult? Got a nasty case of option paralysis because you've got too much to do and not enough time to do it in? Let all your worries sink away with Deadlock's Very Basic Oil Refinery (Special Edition).
With the new oil schema in Factorio 0.17.60, Basic Oil Processing is a one in, one out recipe. So why not have a nice, simple, easy-to-learn machine to match? Enter the Very Basic Oil Refinery. It has just one input and just one output so none of those confusing blocked pipes that try to mix fluids all of a sudden. It even sets the Basic Oil Processing recipe for you, smoothing out that difficulty curve even further. Just plonk it down, chuck some oil in and out comes the win. Smashing!
The Very Basic Oil Refinery is unlocked by Oil Processing research. The real refinery is now unlocked by Advanced Oil Processing because let's face it, it doesn't have anything else to do until then.
Factorio 0.17.60 is required.
