*This is actually the same Addon but in this case, Duke Nukem Mania is actually an expanded version of Duke 3D Mania, Duke 3d Mania was released in 1998 and has 700 levels plus tools and utilities, Duke Nukem Mania has an additional 1000 levels and language translations for the English, Portugese, and Spanish DOS Menus. This file is not by me and I do not take credit for it either, This file was originally on Archive.org and I decided to archive it here.
