Heil Hitler!!! is a mod for registered Wolfenstein, made by Sam Feichter. It was released on November 14, 2001.
Initially announced on August 16, 2001, with updates appearing time and again on the Wolfenstein 3D Dome News, what eventually got released featured only 4 levels, with the project being abandoned shortly thereafter. Feichter would gradually leave the scene through 2001 and early 2002, and would not return until SamWolf in 2006.
