Notes

Black Slime is not a ghost in the usual sense. It is a recurring hazard, contamination sign, and power source all at once. The guide treats it like the foul connective tissue running through the campaign's worst locations, which makes it useful to track on its own page.

Contact Protocol

There is no clever trick here. Avoid contact, clear it with positively charged slime whenever you can, and do not treat it like harmless background mess on the floor or walls.
