Harsh Winter Survival is meant to be a harder world to survive in thanks to the two mods I based this around. Primal Winter, its a mod that turns any world into a wintery wasteland. Visibility is low and mobs spawn constantly because the snow basically blocks out the sun. The description the creator of primal winter decided to say its a world where "A horrible accident has left the world - the entire world - a frozen wasteland. Unending snowstorms rage across the land, from forests, to plains, to jungles, to deserts. The air is thick with fog and wind howls across the landscape". The next mod, which pairs very nicely is Frostiful. Frostiful makes it so that any snowy biome gives you the freezing effect, as if you are in powdered snow. It adds armor to combat the harsh cold, and new mobs/bosses. The combo of these two alone creates a very difficult world to survive and thrive.
