Generous Patrons,
Here's a good-sized chunk of a big refining operation, although I think it's generic enough to pass as some other industrial location you might need.
This time around I included a 'Reference' image that I hope will help you establish the scale and height of the various structures in the scene.
As for the variations, I had fun making the whole place filthy for an abandoned version. Then I took the abandoned version and added trash barricades around a campsite to keep out the zombie hordes (or whatever). I tossed some toxic green smog on that for an even grimmer map. I sent the cops in to cordon off the scene of an accident (or crime). Finally I sent the whole thing into a dark future and/or outer space for a couple more maps.
This map is 2800 × 2800 px with a 70 px (5') grid (40 x 40 squares).
