Linedef type 909, Fog Wall, is a type of linedef special in SRB2. It designates the linedef's middle texture as a fog mask when it is in front of a fog block. Opaque parts of the middle texture will act as fog, while transparent parts will not be rendered. The fog wall can only be seen when looked at from the inside of a fog block.
