NEWWMAP is a very early "mapset" for the 1.0 shareware version of Wolfenstein 3D. Technically sporting 10 levels, most of these are actually original levels, with only the first three slightly modified. The modifications include replacing certain actors with SS or Hans Grosse, as well as replacing all floor codes with 8C. The author of this article speculates that said changes were done via hex editing, as no known map editor was available at the time. The maphead file is not included in the archive and needs to be recreated in order to render the set playable.
