Project: Eisenritter is the second mod released by Wolf Skevos-Jones (WSJ). It was released on December 3, 2002 to much acclaim.
It features 20 levels played in a heavily coded EXE that was based on registered Wolfenstein. Numerous new features include new enemies, new weapons, animated objects, new doors and a selection of music that drew from mods outside Wolfenstein 3D, including Corridor 7.
The gameplay is slotted into different parts, initially starting in an arctic climate before moving through castles and laboratories and finally battling the final boss in a vicious, extensive level.
