The Wolfenstein 3D Shareware:SE was a mod for shareware Wolfenstein, made by Jean Morel.
News of the project made its way to the Wolfenstein 3D Dome on January 28, 2001 and numerous screenshots were posted over time. These included new wall textures and the guard sporting a green uniform.
The project may have been available on either Morel's own site or a different site, as a beta. It is nevertheless still quite an obscure project, and it got canceled in May 2001 together with another Morel project, Project: Nein. Morel did not contribute to the modding scene hereafter as such, but sent a handful of MIDI files to Brian Lowe time and again.
