This 7 Days to Die mod makes the weather more challenging to deal with. It makes the assumption that the apocalypse recently occurred and the air is very dirty. The winds of nuclear annihilation have not calmed or something like that.
Lots of wind will make you want to want to be inside. A very low chances of having remotely nice weather. High chance of rain. More variations in temperature, so clothing will matter more.
The dense smoke/sand/fog particle effects are in every biome (even underwater) so if its too much (visually or FPS wise) there are 2 override mods to this mod to lessen them. If you choose to use one, load only one:
In addition there is another mod you can add that makes it even more challenging. The name is from the xml file it modifies (weathersurvival.xml): Punishing Weather – Survival
Warning: This mod likely does not play well with other biome weather modifying mods because it deletes the weather node on each biome that has it before adding its own. This was way easier than trying to make the modlet friendlier for other modlets by overriding all the similar/non unique environment nodes in the weather section as sometimes there’s only one, sometimes there more.
The forum topic of the mod is here.
