A basement smog in all its funky glory.

Some basements in Neckbeards: Basement Arena are covered in a thick smog consisting of mold spores, gas expulsions, and other types of toxic fumes. This is known as the Basement Smog. While not directly harmful to any denizens of the underworld, the smog does disguise mines laid by Minelayer Cucks. Therefore caution is needed if the smog is present in combination with said cucks.
