toxic reigon: filled with acid and radioactivity/toxicity and you cannot enter without an adaptation (like the hot areas in the 1st region but isntead of a single biome or 2 in a region, it’s one whole reigion entirly) i think this is cool though to expand the world more, i mean i’m also making my own game and thinking of there being a volcanic and toxic reigion in it, and i think it would fit perfectly for subnautica 2 due to DNA adaptations being in ur game :3
