Duke Nukem 3D beta (Lame Duke) L9.MAP (with corrected textures)
This video shows L9.MAP from LameDuke with added textures, which were taken from the April 1994 Build Engine. This map, in original had strange textures that probably explained by having the original builddemo tiles replaced with others without checking on this map.
