Now Toxic Fog will contaminate the air inside rooms that have openings such as open or smashed doors or windows, or smashed walls, to the outside toxic atmosphere. You will need to find a full enclosed room to proect yourself.

Unfortunately this improvement does come with a performance hit in larger, complex buildings when it is foggy.

Compatible with all the gas masks from other mods that I am aware of.

Finally! A reason to use the gasmasks in Project Zomboid!

Sometimes clouds of toxic, bilious vapour rise out of the cursed soil.

You can protect yourself from it's effects with protective breathing gear, which can be found in the expected locations.

Maybe there is some way you can fashion a rudimentary respirator? And maybe there is some way to treat yourself when sickened by this pestilent miasma?

Also, this mod comes with an alternative, even more hardcore version, in which both the fog and rain are toxic, necessitating full-body protection to fully avoid the effects of toxic rain.

Special thanks to aSFIRE [RU] for their excellent Toxic Rain mod that both inspired, and served as a template for this mod.
