"The low hum of filtration pumps echoes through the dimly lit corridors of the Night City South Sector Wastewater Reclamation Facility. Sirens flash crimson against metal catwalks as a red-tinted stream snakes its way through the sediment channels—an unauthorized chemical barrel has ruptured upstream, bleeding a synthetic compound into the water. The fluid pulses faintly, bioluminescent and wrong, tripping sensors and scrambling the automated scrubbers.
A NCPD drone hovers near the spill zone, scanning for contamination patterns, while a pair of biohazard-suited technicians rush in, shouting over the comms: "This isn’t industrial waste—it’s military-grade nanofluid!" The plant's AI hesitates, then flickers offline. Something is changing in the water."
Hi guys,
Here is the final map of the month and I had literally just finished painting the whole thing. It is a rather massive map. I've been meaning to draw this for quite a while as I view this location as a continuation to several of my previous maps.
Here are the maps that connect to this one:
I'm sure you'll find creative ways to chain these maps together in your TTRPG campaigns!




Dead Body
John Doe's dead body is found floating in the waste water with most of his face unrecognizable. How did it end up here? Did it flow through the city's sewerage system or did he get taken out here at the plant? If so, why? Set your players up with a murder mystery hook right here.
Chemical Spill
Chemical barrels used to treat the waste water are knocked over. Some kind of red substance comes pouring out of the barrels, leaking into the waste water system. But this substance doesn't look like standard waste water treatment. It is clearly something else.
Contamination
There are 2 map variants here showing two different stages of water contamination. This contamination starts spreading downstream towards another section of the facility where waste water turns into clean drinkable water.
